Hi all,

Ok looking to get mine remapped to get more BHP and better MPG

question is will it help?

MPG increase yes or no?
BHP increase yes or no?

if yes then what is cheapest and best way to go about it?

Do i get a spare ECU so i have original as backup or put back to normal and spare as remapped one?

cost to remap in staffordshire area?

thanks in advance

you can get kit's to do all that with out having to do a thing to the ECU.

[Shark1e]

any ideas what they are called or where to find them?

[Jimbob]

This Diesel?

If so contact TheBoy or Omegatoy who can put you in touch with a chip supplier.

You need to know your ECU type, and you may need to unsolder the existing chip, and solder in a socket.

The TD's were massively detuned by BMW, this chip puts the performance back where it should be 

Highly recommended by everyone who has done it, I beleive the only downside is the MID is no longer accurate, but you get lots better power AND economy 

[rustym95]

motorfactors have them, there are to meny names to remember but all under £70.

[Shark1e]

yes mate the bmw lump, previous owner my mate said he had it tuned and was too mad for him and smoked when accelerating lot so had it put back, but i think it feels flatter than a witches t*t if you get my drift.

sure he said chip had to come out copied and reprogrammed, so wonder if already has the socket job done?

[Jimbob]

open up the ecu and check, you will need the type (427 or 428 from memory) in order to get the right chip.

[Shark1e]

ok thanks,

what is the procedure for opening the ecu? battery dissconnect? or just unplug ecu?

do i just send off for a new chip or will mine have to be reprogrammed? does mine hold codes for things like remotes keys etc

i have pm'd theboy

[Jimbob]

just unplug it and open it up

(anti static precautions should be used)

you get a whole new chip to plug in.

remotes etc not affected.

all easy (unless your existing chip is soldered in, in which case unsolder, and solder in chip holder...old and new chips can then be swapped at will.  If this is beyond your skills, tv repair shops etc will likely do the soldering work for a small fee  )

[Shark1e]

can solder no probs, just had a call back from a local ecu mapper and he quoted £200 and has to have car to read ecu and order chip from ireland, can have car back and go back in couple of days to have chip put in,

must be cheaper else where than £200 or is that the normal?

TheBoy can source it for a LOT less!

cheers i await his reply lol

Not properly. Plug in resistors, etc. that attempt to fool the ECU are a waste of time. There is a very worthwhile and reasonably priced chip change for the 2.5td that many members have used. Not worth trying anything else.

Just beware that, if it's an auto, you'll need to change the gearbox for the stronger AR25 or it'll fail very quickly.

EDIT: Just noticed it's a manual so go for it.

no not them  it plugs into ecu and the one on car fits into it 2" space needed, seen them on sport shop in motor shop. so have 2 ratings and some go up to 10 ratings.

[Jimbob]

just spotted we have a how2...

Seen those, 'adjustable boost control' don't tell me you belive the bull they say?

All those do is try and fool the ECU into thinking its colder outside and to try and force more fuel in...... but the ECU soon learns and those devices become useless

[Kevin Wood]

Yes, so all it's doing is manipulating the inputs to the ECU to "fool" it into using more boost or injecting more fuel.

Much better to use a proper chip that actually has a map to control the engine outside the "factory" parameters that are present in the original configuration.

hi all ok been to see a remap geezer in cannock staffs today, he reckons he has the correct equipment laptop to plug in via obd socket and modify my tractor and offers such a service that he comes out in the car and customs it for my own needs until i'm happy with changes, i.e more ummph and smoother rev due to turbo timing being modified, also reckons slight gain say 2-3 mpg and no known issues with computer mis reading after remap, normal price £150 but as i work local and paying cash he will do it for £130, he said no need with his tools to open up and pull out chip etc

so over to the experts for your opinions on this geezer, he does own a very to do performance shop and even has a seperate workshop on site for pure tooled up engine builds etc


so questions on a postcard is he for real or is he for a 6ft trench in the woods lol

[goonv6]

If not, I can strongly recommend Motech who do much the same.

MPG increase - possibly a mile or two more per gallon, though certainly no noticeable increased consumption
BHP increase - yes.
The chip that many of us have sends the engine back to BMW spec of 143BHP plus 10%, (so around 150 horses).
Driveability - a very marked improvement.
Much better low-down torque, though a tad of black smoke on initial acceleration. Mine still flew through the MoT emission test though.
Cost of chip - around 70 quid, just 'PM' TheBoy.
Recommended - YES!

He talks out of his @rse. The map on this ECU is stored in a PROM, hence the only way to change it is to open the ECU and physically change the chip.

Kevin

[Marks DTM Calib]

Indeed, there is jack shite he can do by the (non) OBDII socket as the map is stored on a hard programmed EPROM which is soldered the to the ECU PCB!

[Shark1e]

should be interesting when i turn up then, cuz he ain't getting anymore money above the £130 even if he has to pull the chip out, he quoted me and thats that, we paddys aint much for being arsed about. will update later

thanks all

Also, bear in mind that if he doesn't open the ECU he is selling snake oil, so don't pay him at all!

Kevin

[Shark1e]

ok either book me in to the nearest nut house or this guy does what it says on the tin,

right i watched him plug in the lead to the obd11 and it downloaded a hell of a lot of folders and files, like turbo timing, delay etc wastegate timing delay etc, loads took about 90 sec, then off we went to the office where he edited files and after 10 mins said hes ready to upload new files, told me to drive steady for 8-10 miles then should have reset all sensors by then, ok now before i had problems accelerating in 3rd/4th/5th gears, now it pulls in all but more so in 3 and 4, so if snake oil how the hell is it doing that? now when i booted it before it did smoke a bit, now no smoke so where did it go? the turbo does seem to kick in faster now, and less pause between gear changes,
and he never had the bonnet up!!!

still feel it could be better but i honestly do see and feel a difference, so how can this be?

the program he used was something like "engine uitv"
he said if not happy come back and he will alter to suit my needs etc,

so am i mad or is he for real, also he knocked another £10 so now £120 as i kept mentioning the club lol and how everyone would be very interested in the results, and also if it was shite, and shite sticks better than good results lol he agreed.

so over to you all-----

Firstly, let me make this 100% clear.  I don't make anything from the chips supplied by my contact - I simply forward details.  Therefore, I have nothing to gain or lose either way .  Thus my answers are 100% honest


X25DT engine ECU (DDE2.1) is NOT OBDII compliant.

The wastegate on the X25DT engine is NOT ecu controlled, its purely mechanical.

The turbocharger on the X25DT is entirely mechanical, thus not ECU controlled.

The actual ECU software and the engine maps are both stored on (seperate) EPROMS. Note EPROMS. Not EEPROMS. They cannot be reprogrammed without removal, 15mins under a UV tube, and reprogrammed, before refitting.

At best, he has reset some of the learned values in the ECU.  This will soon revert to what it was, as the ECU constantly adjusts its Block Learn.  Actually, disconnecting ECU will do the same as well.



Assuming that he hasn't done one of those resistor 'fool the ecu that engine is cold' bodges, I would say that the (slight (barely noticable), going by your comments) improvements are what you want to believe.  The chips that I have recommended (and had myself when I had a 2.5TD) are immediately, massively noticible - much better power delivery, lots more of it as well.


As I said, I just want to reiterate, I get no backhanders, commision, whatever from these chips

[Shark1e]

i trust what your saying mate but i'm not imagining the difference although i have been back to him after leaving work, and said it could be better, he plugged in a diagnostics handheld to see if there were any underlying errors or faults, result none so all good there,

he then re uploaded the files and it seemed even better than the first time. but i will see tomorrow on the way to work, like you said in the pm even with the chip from terry it won't win any races but you will see the diff etc, but if this guy is wrong then i will having my cash back no problems,

thanks for your info and i will update over the next couple of days, thanks rob

[Shark1e]

just remembered the software he used on his lappy = enginuity v0.4.0 beta along with a obd11 usb lead very similar to the shape and colour blue / purple  of the ones on ebay.

so have i been taken from the rear severly? may well have been.

ok well looks like i will be paying him a visit tomorrow.

[Entwood]

Somewhat worrying ...

a google has found a load of stuff from 2006 on this site ...

http://www.clubwrx.net/forums/tuning-electronic-engine-management/134783-enginuity-tuning-software-released-alpha-version-2.html

all the links to enginuity fail ...... 

but another comment shows it has been renamed to RomRaider

http://www.romraider.com

and is a FREE so-called tuning aid .... 

and it is ALL Subaru orientated !!!!

"touch not with a barge pole" comes to mind !!!

[Shark1e]

urrrmh the software i just dowloaded is the one he used, and is off soundforge free shite i'm not happy now.

can anyone help me with what last 3 digits on my ecu are needed for the new chip jobby, i have loads of numbers and even a mobile number written on it lol

[Dave DND]

Not having an Omega, I can only recall what I have read from here from other Oofers.

You say that this gives a "mild" improvement, but I seem to recall that some of the performance mod chips, (which is certainly the correct way to go), can leave the car so astonishingly quick to a point some members have actually removed them as car keeps spinning the wheels.

 :-?

[Kevin Wood]

At the end of the day:

1) RomRaider / Enginuity is a tool which only supports Subaru ECUs - so whatever he was doing it wasn't ever going to work on an Omega.

2) The map is stored in EPROM on this ECU - so, even given software that's compatible with it, the tuner would have to have opened the ECU to change anything.

I would go back to him saying it's made no difference and ask for a refund. If that's not forthcoming challenge him with the above and threaten to take it further.

I'm sorry to say you have been conned, regardless of what the seat of your pants might be telling you when driving - so don't let him get away with it.

Kevin

[Shark1e]

thanks all just by chance i have to go past his shop today between deliveries so will be parking my artic outside, so keep me covered i'm going in lol

update later

thanks

[Dave DND]

And take it from a Subaru owner, its not worth the constant fiddling about !!

Chip swap made all the difference on mine.

Good luck.

Plenty of space for uncooperative witnesses in the back of an artic.

Kevin

[Shark1e]

lol yes mate plenty of rooooooooooooom lol.

anyway been to see him and he said he will refund the cash, gotta call back in tomorrow and he will have it as he has banked up yesterday, pretty genuine and has offered to solder in new chip when i get it for £45  . we will see once i look at the job.

Get him to put a socket on the board, and not to solder the chip in directly

Can prove a very cheap (pence!) and usefull mod for the future should you ever want to plug the original chip back in, or program new chip with future upgrades

Agreed. No point replacing a soldered-in chip with anything but a socket.

kevin

[Shark1e]

another mapping company called me back to say no probs they can do it but chip has to come out, at a cost of £225 all done, or £185 to custom my chip and i sort soldering or socket myself, say what jesus are you on drugs lol

anyway got 2 diff 28 pin DIL sockets ready (1 x turned edge pins and 1 x what i call fork slots that grab chip leg either side of each pin, new solder sucker, anti-static strap, new solder for chips or circuits boards etc, new roll of desolder braid just in case, gonna even get a rubber car mar to open ecu up on so no chance of any static from table etc, lol still no reply from terry the chip man, hurrry hurry give me a chip. pleeeeeeeease.

[Shark1e]

just pm'd theboy again, anyone know this chip guys telephone number or can get him to ring me please as i want get it so i can fit it a.s.a.p,

thanks rob

pm me if you need my number to pass on, many thanks

p.s anyone know roughly what area he comes from, just wondered if it can be collected faster?

thanks rob

[Dave DND]

Make sure he supplies a new chip, not modifies yours!

That way you have a back up to revert to should something go wrong or the power proves to be problematic

 

[TheBoy]

He's in Oxfordshire.

I have forwarded your details, he's normally pretty quick. Tried to call him to tell him I had mailed details, but got his voicemail.  He lives in the middle of nowhere, so probably a poor signal.

[TheBoy]

He does

[Shark1e]

thanks mate, do you know how everyone pays him? chq? paypal? bank transfer? quickest suits me, mny thanks again.

rob

[Shark1e]

full refund from the laptop cable chipper so good to his word,

now waiting for contact from terry the actual replacement chip guy so i can order a new chip from him.

i hate waiting lol no patience.

[Shark1e]

whooooooo hooooo terry rang and i just paid him for my new chip so hopefully all will be up and running in a few days once it arrives and i fit it.

stay tuned

[mr ICE man]

just checking but the gearbox upgrade is to an ar35b not ar25 isnt it?
was sad above that need to upgrade to ar25 which i think is the weaker of the two?

[Kevin Wood]

A chipped 2.5TD needs an AR35.

Kevin

[mr ICE man]

woo i got something right!!!

[TheBoy]

A chipped 2.5TD needs an AR35.

Kevin

Some might say an unchipped needs a ar35 as well, as if driven hard (is there any other way ), an ar25 will only have 120k in it...

[Shark1e]

Chip arrived from terry yesterday, only just had time to fit it.

so i took my time and managed once i had flipped the ecu board to desolder the wrong chip lol never mind resoldered and set about desoldering the correct one seeing it is upside down lol,

fitted 28 pin socket from maplins £1.24 inc vat, and soldered in, CHECKED all solder joints with light shining from behind circuit board and proceeded to align and gently push in new chip, and all done.

refit all ecu bits back together and nothing left over so thats a good start 

back out to car and refit ecu then both battery connections,

turn key reset clock as i hate the clock being wrong,

start engine and great it sounds all ok.

off the drive and up the road for a quick burst.

OMG whoooooo hoooooo what a bloody difference go on terry my son, and by the way terry can supply 2 types of chip, 1 = mass power difference and fuel economy but not as aggressive and no smoke on booting as chip 2.
chip 2 = manic power and black smoke upon booting the pedal and massive power and fuel improvement. 

basically chip 1 total difference and mind blowing from bog standard vx chip

chip 2 for the nutters out there i guess who like to leave a james bond smoke trail upon running away

so score on impressed well gotta be 11 out of 10 

oh yes if you gonna do this mod, buy a decent solder sucker i would have been stuffed without it.

job well done and lets not forget the big up for you all who gave advice on the chip fitting and where to get it from,

cheers

[TheBoy]

427 on a manual box does appear to be a really good combo.


Now, keep an eye on rear tyre tread - mine managed 4k (New Avon ZV3s) .  It was a fun 4k though

[TheBoy]

oh, and pass you feedback back to the chip guy - it helps him explain the options to other people

[Shark1e]

lol will do mate, this chip version is just right i think, the more agressive one may have been to much, not getting old just need to keep my HGV licence lol

[TheBoy]

lol will do mate, this chip version is just right i think, the more agressive one may have been to much, not getting old just need to keep my HGV licence lol

The smoky one is a bit OTT imho. Fun, but loses drivability imho. 

[Shark1e]

update get the chip like mine the girl goes like a rocket ship now, very very happy, 5th gear at 1900rpm or above puls like its heading for space. i have had to add buzz aldrin now as  named driver lol

well done all in making one very happy omega tuned tractor driver 

[blackviper90210]

Hi all,

just read all the posts on this subject...wow. [smiley=2vrolijk_08.gif]

Now is the same option available on a F/L 2.5 petrol elite or just the 2.5td?

Cheers, Dave

[Jimbob]

2.5TD only sorry, very little gains available through chipping on a petrol one.

[blackviper90210]

Oh well. 

Thanks anyway Jimbob!
