Just wanted to say WOW! And thank-you to those who hooked me up with chip guy.
I've had chipped turbo diesel cars before, so I knew.what to expect, but this is beyond that lol. Great fun when needed.
It's a plus 10, so plenty of poke.
:y :y ;D ::)
-
Don't enjoy it too much, I wrecked a brand new set of crappy Avon ZZ3's in 4k when I chipped mine ;D
-
A fitting end :y
-
Whats all this chipping business then guys, I chipped my boys xbox about five years ago or my brother did, but how does it work on an Omega ? can I chip mine ?
-
Afaik, there are petrol chips available bit the power increase is not as large.
Diesel is easy, more fuel, more air. And it doesn't matter if it runs rich. Excess fuel gets sent out the exhaust it the form of black smoke!
You'd have to have a proper remap with some light mods to get power out of a petrol.
As for tyres, its all good, still got to wishbones etc and get WIM'd lol.
Gonna need new tyres any way soon lol.
In the mean time lots of sideways fun at roundabouts and junctions lol

Just be careful buddy - you've now got nearly 160 hoses under your right foot! :D

I understand that you are one of the ones not suffering a 1500rpm stutter?
The chip guy and I are developing a theory about this...

Me neither, 428 ECU, +5 chip. :y
-
Correct, a 427 +10,
No stutter and LOTS of power :D
I'm still getting used to it, but drove one of my favourite roads today and it was just epic.
What's the theory on the stutter then?
Have you asked what spec the models are. Cos mine is a select, pretty much the base model. No electrical toys to speak of really. Thought it might be some hardware or software conflict ecu wise.
I've got no complaints at all with it. Other than the amount of smoke from standing start lol.
I end up leaving the person behind me swimming in diesel lol.
I figured it was between 150 and 160bhp at a guess.
Is that about right yeah? I know sethsmate just said 160bhp.
Just wondering if every one who knows about them agrees.
Thanks
-
Does anyone near brackley have a TD with 427 ECU?
-
GOOD NEWS!!!
yeh some of the later ones suffer a bad stutter around 1500rpm including my new one!!! sob :-/ nothing shows up when doing live data, but we have a few ideas kicking around, will get it sorted!
enjoy the power, when you casn keep off the loud pedal you will find it gives more mpg as well, but that ususally takes around 3 weeks before you get fed up playing with it ;D
-

lol bet i turn out to be the nearest!!!

You don't count - yours suffers the problem. Ideally after one that doesn't ;)
-
yeah it is odd, they might have changed something in the later ones.
as for getting bored of it, not likely lol.
I've used up a tonne of fuel in the last 200miles with it lol.
Tis still good fun.
This i'm going to lower the car in the Apex spring kit i found (only one i can afford), and then do wishbones, and any bushes that need doing, then WIM.
Oh and then 17's.
Should handle nicely rhen, its a bit wavy atm.

Haha, just noticed that. That's a lot of hose pipe.
-
Was out on a run today, Intercooler hose came off my intake manifold at the front.
(as mentioned in other post).
Reason for mentioning here is,
Just after this happened, once replaced and tightened, i felt this vibration you speak of for the first time. was like a loose wheel on the back, like a slight knocking when cruising in 5th at about 40mpg (1600rpm). as soon as i let off, or put my foot down and the turbo kicks in a little more, then it would disappear!?
(and before anyone says anything, ive check everything else too, was definitely engine vibration i felt)
Later on, i didnt notice it at all.......So very strange.
Is this similar to the type of vibration you have happening?
-
yep!! try it on a flat road top gear 15 to 1600 rpm and feather the throttle, if you get it right it will shake the whole car around but as soon as you back it off or push the throttle it goes!! damned annoying!! especially when in a queue of traffic travelling at the wrong speed, have to select asnother gear to get rid of it!!! only happens on certain cars though
-
ok will double check later when im out and report back.
thanks
-
Soft engine mounts affected by the extra torque/power. Had the same problem a long time ago in Fiat 124 sports.

As yours has the '427' ECU, it seems like you've actually got the problem that several members have experienced when chipped.

and yet today, when driving, for the life of me i could not replicate what i felt yesterday lol
So who knows
Doesnt bother me anyway, but i'm interested in the theories

When I had the chip installed on my TD it drove ok but chucked out heavy smoke on hard acceleration. No stuttering around 1500rpm at first, but eventually I guess after around 5,000 miles use. A dose of 'Diesel Magic' in a new filter helped matters with the stuttering but it was still present.
Obviously blocking the injectors more easily, hence more smoke when fitting this type of chip. But yes it was bloody good fun to drive :y

Yes mine is smoky. I do feel sorry for whoever is following me lol.
-
well i have the 007 chip fitted in micks ex car now, pulls just as hard as the full fat version but no smoke or very little anyway!!
still got the stutter though,
as regards the unable to replicate it, you need to be on a dead flat piece of road get to 1600 rpm then back the throttle off till its not accelerating and not decellerating, it will appear!!
but the slightest oincline or down hill bit and it wont and it only happens between 1500 and 1650 rpm
-
What's the difference between the chips then? I think mine is a full fat one. But tbh I'm not sure lol.
Certainly feela good, but essentially the saying is true,
"no smoke, no poke!"
It's how diesels work.

lol the stealth map, called 007 is around 10bhp down on the full fat chip but its enough to stop the smoking, still pulls like billyo though!! :y

And Omegatoy is like Miss Daisy. We went for a drive Sunday, and he never went above 50mph :P ;D

no we didnt cos 50 in top or rather 47/49 is exactly where the stutter occurs, unfortunately the roads round brackley are not very flat!! so we spent ages trying to get it to do it and capture it on tech2 to read the live data!!
but TB was feeling queasy trying to read while travelling so i could,nt go any faster for fear of a pebble dash effect on the interior :o :'( lololol
-
managed to get the vibration again today.
So yes, i do have it...confirmed.
-
hi, saw your post- any help on getting mine chipped would be appreciated.....pls email me on dkbastille on google mail if you cant get hold of me here...thanks Dave

Always suffered that - I was surprised I lasted as long as I did to be honest... ...another 5mins would have seen chunks...

I know a man who can supply chips, a fair few on here have them.
You cannot chip an Omega TD auto without putting in a stronger gearbox.
If you have a manual, or an AR35 auto, then its possible

How bad is it? Omegatoy's is really bad, its the first one I've felt.
We are trying to ascertain if different ages of car make a difference.

Is it only manuals that are seeing the issue?

The RPM is happens at probably masks it from autos - auto would drop a peg, lifting the RPM above the zone this happens.
One theory was the idle switch, and with the power coming on strong at this rev range (about 1450-1550 rpm) when chipped, if no/inadequate hysteresis existed.
Live data shows that it happens right at that point of the Idle Switch activating, but try as I might, I couldn't capture a snapshot right as it happened. And to be honest, by the time we managed to get it to run for long enough to get a snapshot, my dinner was about to reappear :-[

::) ::) ::)
-
Ok, well as far as I can ascertain, its not particularly strong. To the point where i really have to work quite hard to produce it. As such, it does not annoy me yet. Or should I say, in no particular circumstances of my daily drive does it become truly evident.
Mine is a 97 td estate manual, running a 427. It has 112k miles and is a select spec.
Could it be a torque issue related.to engine mounts as suggested in a previous post?
Or is it just something to do with resonant frequencies and vibration created by a longitudinally mounted high torque 6 cylinder engine?

The thing that rules out engine mounts (Offside particularly troublesome on TDs) is this issue only seems to present itself on some 427 ECUs. Doesn't seem to affect other ECUs either.
I think the 427 is unique in that it does seem to be the most responsive to tweaking, not sure if that makes a difference. Certainly my old 428 tractor didn't start to pick up until about 1700 rpm, whereas the chipped 427s all seem to start to come on song around 1500rpm
-
Yeah i can see how that might limit the search.
Glad to hear mine is best one to have lol, but also worst one to have.
Just drove back from work and had it a little, and its noticeable, but honestly feels like a wheel wobble lol.
Its interesting that they were different ECU's available at all on the same engine.
Out of interest, is there any difference in vibration response between different chips?
+5, +10, 007 etc
Also, does anyone find that there's less smoke on hard acceleration with the +5 (i know the 007 is smokeless-er).
thanks

I only ask because I know that on engines with very high torque output even DMF's experience a point of resonance (which the ECU map masks by backing the power slightly at certain revs).
Some engines are worse than others (e.g. Mitsubishi's require that you select different software for the two types of flywheel!).
Not sure on this one but, its possible that the MAP change does not account for this and hence the nasty point.....also hence why it may not occur on Auto's

Could the amount of effect be caused by variations in DMFs? Do DMFs wear (I know they fail sometimes)
-
They do wear which would make things worse.

hMM,
I think Mark could be on to something here!! reason being im fairly suire the dmf on me new motor is fubar!!! its definetly out of balance and a couple of times ive had it chatter on me, obviously i wont know for certain till i strip it and change it ,
but that could explain why mine is so heavyily felt throughout the car!!! shame is got a 1600 mile drive tomorrow just hope i dont get cvaught in to much traffic!!! :'(

Mick
yep all done Mick thanks, wheel bearing was a idiot to do, not so much the job but trying to press the old one out was a bit of a herculean effort! over 3000 psi before it shifted the hub, straange noise at front is definetly not aircon compressor, i have a feeling its realted to the dmf, fully serviced, all the wy through now, all fluids and filters changed including brake fluid, new wipers and a host of other bits and peices ddone!!! will post up how the journey whent when i get there!!
-
Seems i'm switching to the +5 chip ASAP!
Here's a summary why:
Before chip i did a 70mph 300mile run on m4 to london and back, and got 42mpg....AND, no smoke.
WITH chip (+10), i get SMOKE with very little throttle at all and on a 120mile run at GRANNY pace, literally driving as economically as i know how to (i've done well in the past with chipped diesels and MPG) at 55-60mph very smooth little stop start, i only achieved 37mpg....
Literally could not have driven any more economically.
So i figure the overfuelling (black smoke) is excessive, and as such is causing inefficiency in general fueling at normal speeds (but still gives good power up top of course)
Going to see if the +5 will lessen the smoke and hopefully pull the mpg back up.
I was expecting to see an increase in MPG tbh. And i know it is reliant on driving to the new style of the chip and using the extra torque to change earlier etc, but believe me i was trying, HARD! lol
so will keep you informed, if you care at all lol ::)
-
Got here safely!!! 007 chip fitted and it averaged 43.4 to the gallon!! however i only need to take it to 2.5krpm through every gear it pulls beautifully through the gears,
owing to the new speed limits of 110k here, i set the cruise at 113 when i got to a boring motorway, which was 76mph or thereabouts,got here in ther same time as i normally do although i must confess, didnt stop for as long or as often?
perhaps owing to the lower speeds requiring less mental concentration?,
all in all chuffed with it!! :y

Exactly, 43.4mpg at 76mph wth cruise on and your changing gear 2500!!
And. I'm 37mpg at 60mph without cruise, and changing gear at 2000!
Something is not right.
You're not taking that reading from the MID are you? Lol.
I've not been offered 007 chip from chip guy, so will have to make do with the "+5" and hope I see the right results
-
Hmm, possibly but i completed a full service everything i.e oil and filter, air filter, new wheel bearing, topped up the diff and gearbox, full stripdown check free off rebuild brakes, tyre pressures set exactly,tweaked turbo wastegate a little ::)etc etc,so with everything frsh and free it may have made the difference?
and cannot remember but i think 007 chip is actually a plus 5 its around 10 horses down on the full fat chip, thoroughly recommend it, :y
-
Yeah,
Well most of the things on that list have been done on mine recently too..
Tyres are defo set right, had oil and filter change 1000 miles ago.
Not sure bout gearbox oil, will check.
Brakes are free and not sticking at all.
If u don't mind me asking, what adjustment have you made to the wastegate? Did you tighten it to increase boost? This would help burn off extra fuel and hence produce better power.
I think the 007 chip is the +5 too. Spoke to chip guy about it today.
Ideally I'm looking to maintain reasonable mpg. So we'll see how things go with the new chip.
Otherwise it back to no chip and driving everywhere at 56mph in the hope of achieving the 50mpg book figure lol! ::) ::)
-
yeah tweaked it a little in an effort to reduce the 1500rpm shudder helps a little as the boost comes in earlier, going to wrap the boost hoses next to stop them expanding so it comes in even earlier,
however do not just wind it in a few turns!!! max and i mean max half a turn and try it if you dont have a tech1 or tech 2 to see the boost!! all to easy to overboost it and cause BIG problems!! takes time to get it exactly how you want it this way but much safer!! my other one is tweaked the same way and is full fat chip makes no smoke now,
but drove very slowly onto a extremely steep (car grounds out at the start of it so slowly does it onto drive)driveway today left twin black streaks for 7 paces(mate is 6ft 4 so his paces may be a little larger than most,lol :y
p.s dont forget you will get extra boost only until the wastegate catches up!!
-
Hmm, thats interesting about tweaking the wastegate to increase pressure.
Its actually something i am quite familiar with.
I tightened the wastegate on my tuned rover TD, bringing boost from 16psi, up to 19psi. This was the recommended maximum for that car.
Do you know what sort of Mpg you get from your other full fat omega? As i would like to keep the full fat chip if i can, as i like the power, but ideally i would still be able to get the mpg i want under economical driving conditions.
I have a boost gauge and the feed hose from my old car still, could i fit this is an easy way to measure the effect of the wastegate adjustment?
And when you say about the black streaks, are you saying that it was smoking?
and when you say "get the boost exactly how you want it", do you mean a specific level of boost eg. a certain psi, or do you just mean to a level of reduced smoke using a visual measuement....?
thanks

lol yep always has given me 35/36 running about and 42/43 on runs(spain to uk and uk to spain) however its an early one with no maf, and it has been tweaked with turbo pressure etc etc (see post damn good car in general car chat)
boost guage is a good one?wouldnt like to say use it, it could go wrong so easily, i did my old one with tech 1 connected up so i didnt overboost it, like a mate who just screwed the wastegate in TO WHERE HE THOUGHT IT WAS GOOD, then wondered why it blew up!!!
i DID have it boosting at 2.4bar at one time but it was to high,boost pipes were expanding hugely,
ran strong but just spun the wheels up and gave severe axle tramp when it did it,(dry roads) also made the prop shudder on the centre bearing backed it off to around 2.1 i think and it seemed pretty good there smoke wise, just a little at high rpm,
twin black streaks were from the tyres!! oops but it is a concrete drive so pretty easy to spin them up.
each car is different bud, so personally i would do it a little(half a turn max) test it then do it a little more if you thought it needed it? alternatively you can try searching the tinterweb and see if anyone knows an exact figure to boost it to, ? just be careful with it!!
-
hmm,
I'm torn now.
not sure if i should fiddle and keep the +10.....
or swap to the +5....
choices choices :-/
-
Just been having a read over on bimmerforums.co.uk
They have a chip guy too, who deals with m51 chips (the omega 2.5td, which i'm sure you know).
He reckons there are 2 chips that should be done...
i am aware there are two chips in the ECU, and i'm aware that one of them (the one i have replaced), is for the fueling. But he always replaces both, and the 2nd one is changed slightly too.
I'm intrigued for 2 reasons, 1 being, why is it different for the omega
and 2 being, they map to 170bhp ish easily and with little effect on mpg....
why is the chip we have (full fat) only around 155-160bhp at a guess.
ALSO, lol,
they reckon that on some of the later 525tds models, the turbo was controlled by the ecu, and earlier ones manually.
What is it on the omega engine.
I really want to keep the +10 chip if i can....REALLY REALLY lol.
But i just dont get the fuel drop i had.
I'm running it now with the original chip for a while as i removed the +10 to send back, and i'll see how it does on fuel now around town and on some journeys. So far it seems good again...who knows.
Discuss... lol :D
-
there are a couple of differences between bmw installation and vaux installation!! agree with the 2nd chip probably needing doing we changed mine for an earlier one that doesent suffer the dreaded stutter, it made no difference!!!
bnw has a larger intercooler and there isnt room to put the bmw one n the omega especially if you have aircon, the turbo is in a different place, and rumour has it that it is a smaller output on the omega, this i havent confirmed,
however on my old one i wired the intercooler fan to a manual switch, when i wanted extra power i could switch it on and the nlet temps would plummet, and the power or throttle response is much better, havent done it on the later one yet but i do know the fan is seized >:( which is normal, as ecu dont switch it on till 100degrees(stupid) so may play with that later on, :y

Not quite. It turns it on with the cooling fans (genuine cooling, not when they come on for A/C). This is one of the reasons I recommend binning the power sapping viscous turd bolted to the water pump - the electric cooling fans pop on a little more often (ie, whenever you hit traffic after a run), keeping the i/c fan in regular use ;)
If the engine/cooling is well serviced and in good condition, this should cause no trouble for most (towing and hot countries, need to keep an eye on it) - mine was driven very hard everywhere, and I never had any hint of overheating once the car was sorted.

Where does this 2nd chip go in an Omega? and what chip do I need. I'm running a +5 in the 428 ECU at present. Not much more smoke apparent than standard. MPG is rubbish, but then has never been that good since the previous chip was fitted. Best not to drive an auto Omega if you're concerned with MPG. :y

I didn't need to change my other chip when I had a 428 Omega (same colours as yours as well). autos dont suffer the stutter, as the rpm is always above that rpm (and potentially it could be dmf related).
I used to get around 32/33mpg from my chipped 428 (actual, not MID), driven hard

Yes but yours was a manual!

That's about right when running locally - even with Mrs Sethsmate giving ours the beans! :D
Auto-boxed TDs are, well, pretty crap. >:(
Markseth's previous TD auto confirmed this - low 20s mpg :'(

That's about what my TD auto got I think (my old posts will confirm, no doubt) - I just thought mine was a ropey one! ;D

Mine gets that on a run, but about 26/27 locally. :y

'Fraid not, it was most definately an auto... ...unless it could do 125mph is 1st gear ;D

Very interesting, I wonder why mine is still so poor :-/ :-/ :-/

Got here safely!!! 007 chip fitted and it averaged 43.4 to the gallon!! however i only need to take it to 2.5krpm through every gear it pulls beautifully through the gears,
owing to the new speed limits of 110k here, i set the cruise at 113 when i got to a boring motorway, which was 76mph or thereabouts,got here in ther same time as i normally do although i must confess, didnt stop for as long or as often?
perhaps owing to the lower speeds requiring less mental concentration?,
all in all chuffed with it!! :y
Glad about that, she's a good old bus....just needs a little TLC.
Should do you for a few miles.
