Yo..

My cav turbo has Greddy emanage ultimate controlling a pretty high spec including forged pistons etc, hybrid turbo, Fmic, Greddy boost controller, AEM AIR/fuel wideband, etc.

Currently it's mapped for 250bhp@1bar at hubs. It was only mapped to this spec because a misfire developed- this has since been cured, so am looking at getting it up to the 1.5ish bar it's all geared up for.

What I want to do is get it 'live mapped'. I need someone with experience in doing this, and in particular with the Greddy emanage setup. With me driving and the 'mapper' controlling and watching (and instructing when to boot) I am unaware of any real disadvantage doing this over attending a rolling road. Please correct me where you see fit here!

As I will be attending a rolling road day in October, I'm not bothered about an accurate (ish) power/torque printout, as this will happen then, also I can't see the point in paying for rolling road time if I only need a guy.

I can't find anything that's what I'm after via google, just wondered if anyone on here could advise/point me in the next direction?

Ta..

Not really a lover of rolling roads myself. Brother in law has taken his car three times (different rolling road each time) time and none are anywhere close to each other.
If your having a "live re mapped" done do it on the road where you will use it, not on rollers.....

 Just my opinion 

[aaronjb]

And I'd say differently While I mapped the MR2 entirely on the road I'm well aware there are fairly large 'holes' in the map that are either because:

a) It's an area of the map very hard to visit on the public road (odd cruise loads, high speed cruise)
b) WOT at high load

It's hard to have a sustained period of WOT in 4th gear to generate high load values as you're then doing silly speeds (I know a fella who mapped a race-prepped GTR on the road, the top end speed was three digits beginning with '2'!)

A brake dyno is the best place to map a car, then tweak the map for real world air temperatures on the road, IMHO.

Don't try and use an inertia dyno, though..

That seems to contradict putting it on a rolling road though to me.

But the AIT corrections should be a global thing (well, they are in my standalone) so all you have to do is make sure that the global enrichment is right as the temperatures drop (they'll be somewhat higher on a RR)..

I am not a re mapper, but I sat next to a very good one doing my own car. I asked several questions as you do when interested.
He told me that "on road live mapping" was best, also top speed in top gear was not needed to get peak power for the re map... Or words to that effect.

I know when my car was done top speed was not needed, although granted 60-80 was done alot, then had to go through the gears but top speed was not reached.

I arent arguing by the way here just interested in your view

That's what opinion I have adopted from what I've heard, another reason for wanting it live mapped. Would imagine the local long steep hill in 4th would give a pretty good load if need be 

But where do I look to find someone suitable to take on the job?  :-? Don't want any ol' monkey doing it lol, my mate had his scooby done the other week, (on the same Sunday as someone else on here, ironically) but apparently he was like 'nah mate I only do scoobies'

[Darth Loo-knee]

Andy Forest did mine who also only does Scoobs.

You must be on a Cavalier forum where someone has had it done... Can they not give you any advise? Other than that email Andy Forest and ask him I would imagine he would no someone.

Yes mate I'm on CTOC, tbh I don't think it a norm combination on a cav but anyways, that enquiry got as far as recommending the usual rolling road equipped tuners.. Although I will dig the thread back up and ask again, was a few weeks ago now. I think my best bet might be to sign up on a jap car forum, and ask there.. I mean, surely all the same thoeries would apply with regard to fuel ratios, boost, anything else etc, wouldn't have thought it'd make much difference, other than where the operator would attach headphones. This Greddy unit was 2nd hand off a pulsar if that counts lol so its the same unit, with the same element of control, regardless what car it's in??

Is he easy to find an email address for? I would imagine a quick google search- I'll send him an email see what he can suggest  good shout!

[maracus]

This the one??

I am rather interested in your outcome to be honest, please keep me posted.
If that fails I have a place near me called GT Motorsport I think its called who do all that kind of thing or so I am told. 

[maracus]

Ay I'll let ya know when I get a result lol, I nearly got it done at TDI a while ago, but after they set it all up on the hub dyno, (must have been sat there 45 mins) they then realised they should ask me if I had the software disk!!!! I didn't!!! And they wouldn't download the latest version and try that  so hence I still need it mapping...

Will keep ya posted 

[kingycos2]

Take yourself up to Blackpool for the day, visit Stu at Motorsport Developments (MSD). He is renowned as possibly one of the best, if not the best at live mapping and tunning. I've had 3 Saab aero's and my sierra Cosworth goes there every year to be done, the results are amazing and he is very highly talked about on the RS/passionford sites. I don't trust anyone else with any turbo powered car I've had, my sapphire has done 130,000 and it drives like 40,000, IMO its down to their ability to maintain cars like that, I also took my cavalier turbo there about 6 years ago, which i sold shortly after.

You don't need VMax in top gear no - but you do need to cover all of the peak load cells (at least the ones it's possible to get to) in the map, otherwise it'd be possible (though unlikely) to drive 'off the map' - whether or not you can do that in lower gears depends very much on how tuned the car is..

I can do it in the MR2 in 3rd, but it flies through the map so fast that the software can't log fast enough (12 samples per second, so quite slow - I imagine a Link/MoTeC setup would have better resolution) so I have to use 4th gear.. which means you're going pretty damned fast by the time you've logged 7200rpm

Must admit I was severely disadvantaged doing mind - I was driver and mapper at the same time.. lots of logging, parking, adjusting map, logging, parking, repeat ad infinitum

Better to do it as a team of course - one driving, one listening to a pair of det cans & mapping..

Though I still think a brake dyno is better - if nothing else, you're less likely to lose your license doing it 

(Andy is one of 'the' names in mapping though, so I have no reason to doubt he hit all the required parts of your map & so on.. although whatever ECU it is must log very fast to be doing it in a gear that only hits 80mph!)

[Kevin Wood]

Well, my Westfield has never seen a rolling road. Started off up the road with no map at all and within 30 miles on the road I had it running pretty much perfectly.

Mapping on a rolling road has advantages in that you can hold high speed/load combinations until the engine melts, but mapping on the road gives you the transients that happen in real driving that you can't reproduce easily on the rollers and yes, the engine operating conditions will always be slightly different. That should be compensated by intake air and coolant temperature sensors but, IME, you're often mapping out deficiencies in these too.

IMHO, you can't map a car on the rolling road without at least driving it a few miles to check if it's a dog to drive and iron out the little flat spots and hesitancies. Vice versa, you aren't going to wring every last few horsepower out of it without a rolling road, especially where it comes to tweaking the ignition map where the changes are subtle and difficult to detect with a seat-of-pants dyno.

Having said that, I could have spent a couple of hundred quid getting mine setup and would have been none the wiser as to how it was done. As it is, I spent that money on building a wideband lambda controller and I'm now equipped to tweak it whenever required, and have gained an awful lot of knowledge doing so. Depends whether your desire is for a turn-key working car or to learn and do it yourself.

A wideband lambda sensor is totally essential if you're contemplating this, one you trust to tell you the truth, too, especially with forced induction because it's so easy wreck an engine if it goes lean.

I find you can get the basic map dialled in by watching the lambda sensor and tweaking the map on the fly (helps if someone else is driving, but I didn't have that luxury ). More detailed tuning is best done by processing a data log that includes varied driving. I had a script that processed a datalog into a percentage error for each cell of the map, and then applied it. A couple of iterations of that and you've basically got a car that's indistinguishable from one that's had a half day on the rolling road.

It doesn't really matter if you can't hold it at peak RPM at WOT with this method. As long as you've done it for long enough for the lambda sensor to settle you have the information you need in the log.

I'm not familiar with your engine management. Most of my experience is with the various incarnations of Megasquirt.

Whilst they are all basically the same, one thing you need to be able to do is find your way around the mapping software to make real-time adjustments, so, if you can, find someone who's familiar with your system.

[aaronjb]

(helps if someone else is driving, but I didn't have that luxury ).

That sounds familiar. Don't worry, Kevin, next time you want to tweak the map in the Westfield ... I'll drive!

(Actually the first run out in the MR2 with the turbo fitted saw a friend of mine driving - it's very hard to map when you're pinned against the door flying around a roundabout while he 'keeps up' with an Evo VI  )

Ok thanks for ya comments peeps, I have a few people to be trying now so hopefully should get somewhere with it. Also been given a couple of companies to try, A&M conversions and Rs tuning, so hopefully I'll have an interesting update in the next few days...

[aaronjb]

Lol sounds a laugh and a half

It's the only time I've ever felt car sick in my own car  Still there have been many hilarious episodes with Mark and I in the same car - like the time he was trying to convince me to go round the roundabout faster, and I bottled it & went up the A1 sliproad instead of back to his house.. All I heard was "Why did you do that!?" - because I thought we were going to crash into the bridge, that's why!

Fair point, but if I was going to be chasing horses with such degree of precision, I'd be running standalone management and distributorless ignition

I can say you need a faster cpu

generally speaking for here, initial custom mapping done on dyno, then final  corrections on the road :-/

[aaronjb]

I can say you need a faster cpu

Nah - the processor in the ECU is doing far more than 12 calculations per second, and the laptop is capable of much more - but the interface between the two is RS232 at a relatively low speed.. so you can only read so many data points per second (and the ECU insists on pumping out a full frame of data each time of everything it knows about, there's no selective monitoring to have, say, only RPM/load/knock/lambda at a faster rate)..

To be fair it's a pretty inexpensive standalone (Apexi PFC ~£400) compared to the competition (MoTeC, Link XLEM etc) - I think even the newer Megasquirts have eclipsed it in terms of speed, but it's still a default choice for a lot of Japanese cars here, in the US and Japan simply because it's plug-n-play for a huge number of cars (even comes with a default map, usually ripped straight from the stock ECU by Apexi so you can plug in and drive on a stock engine)

Agreed and hence I would say that an on road setup would be close to a rolling road (and to be honest, the results I have seen from rolling roads vary hugely!)

All the skill is in the guy mapping, after all, not where it happens

Though oddly enough an aquaintance of mine has just had a new engine delivered - 7ltr of Ford V8 built and set up on an engine dyno. Mmmm. Torque.

under normal conditions rs232 can handle more data flow something wrong there..

IIRC each 'frame' is somewhere around 512bytes (4096 bits), and the interface is only 38400bps.. ~12 samples per second

Nothing wrong, just a slow interface.. to be fair I'd much rather the ECU spent it's time calculating fuelling than shepherding an RS232 interface

(Did I also mention that the software used to program the ECU is written in Visual Basic? Well, unless you're an Apexi dealer and can read Japanese, then you can use the 'official' software .. but I'm neither )

1/12 sampling is enough to populate the map with logged A/F ratios and knock levels (and injector times, AITs, MAF reading, etc etc) after a couple of WOT pulls through 3rd or 4th gear, though - and it zips through the map pretty fast in 3rd

rs232 was reaching 115kbps when grandma was virgin

agreed.. ECU is also busy reading from sensors but must admit car manifacturers use the slowest cpu/hardware possible and those ecus cost more than an arm and a leg if you try to buy..

so imo microsoft must start custom ecu programming bussiness , so we can send viruses to others cars

[aaronjb]

I forgot to add as well, the interface on the ECU itself isn't actually RS232, it's some proprietary signalling. You're meant to buy an interface from Apexi, but that's only available to dealers - and AFAIK they only exist in Japan..

So what you have to do is buy a little interface box (a "Datalogit") which does the translation from 'something' into RS232.. That's probably where the bottleneck really lies as it's a very basic circuit inside the box - although it does also give you two analogue-to-digital inputs to hook random things up to.

As I say, it's all built to a price point £400 is pretty cheap for a full P&P standalone, and the Datalogit is ~£50 secondhand..

The next project will (if it doesn't end up running a Holley carb ) probably be run on Megasquirt purely because I like the homebrew 'tinkering' aspect, and it won't be my only car (the MR2 was my only car when I put the turbo etc on!)..

yep.. this explains the reason..

[aaronjb]

I'd love to have tried the official software - though from what I can gather it has far less features than the aftermarket.. there's even a program ('CoPilot') for the MR2 & PFC combination that will auto-tune (to a point!) fuel and ignition tables.. very handy when you're one-man tuning

[maracus]

Well.. Not much joy so far; I just got the car back together last week after a head gasket failure  :-/
Now I gotta order a new o2 sensor for the wideband- she's giving lean readings but the petrol may as well be coming neat out the back- the plugs are black as fook!!

Anyways when I get it done I need it mapped before the 11ish of October, so either need to find someone whos up to the job of a live map, or bite the bullet and take it back to TDI, which wouldn't be a bad thing, just more expensive than need be!

So the next update will probably be 'got it done at TDI and it's rapid' so if anyone knows anyone other than andy Forrest, Rs tuning,  GT motorsport or MSD (who didnt even return my email) please suggest don't really need a rolling road as it's getting rr'd anyway in October with the cav turbo guys, i only want it mapping, I would get Rs to do it but can't do it on the day coz they're rammed, and it's a long way to go twice lol

[Kevin Wood]

The latest Megasquirt logs directly to an SD card, so I'm interested in how quick that will log. I've built the ecu. Coming to a car soon when he gets round to building it.

Out of interest, what wideband? If it's an Innovate LM/C-1, did you know the O2 sensor is the same used on most VWAG late model cars? The current gen Golf, for example - about £50 from VW..

I googled Bosch 4.2 LSU o2 and there coming up about £60/£70.

Just need to pull finger from bumhole and order it!!

This ones from 'Riga' wherever the heck that is, EU lol, and I remembered the price wrong it was £52 free postage, but I feel reluctant as one from a UK based ebayer, £68 so I'm like  :-? hmmm it says it's the genuine new article and 99 available but.. I can't figure out if I'm just being paranoid after my last eBay purchase for some Sealey Allen keys turned out to be a mickey mouse poindshop set (refunded, finally!) or if the price difference is too good to be true..

Think I'll chance the return postage and get the cheaper one, so long as the description fits upon arrival lol

Hey,
Just to summarise for those who are following, I got the car mapped up yesterday...

On a hub dyno courtesy of Torque Developments International in thurruck. I was not having much luck finding someone to do it on the road for me, had a think, and decided it'd best go to tdi, as they know the car from the previous owner. Plus obvious advantages of hub dyno accuracy.

So the outcome was an increase from previous 250bhp / 241 lbft @hubs,(which showed down on the day by 3hp, oooooohhhh!!!!!)...
To a whopping....

255.4 bhp and 263.9 lbft.

Ok so it was only a marginal increase in boost, slight adjustment to the fuelling, hence only a few more ponies, but we maxxed out the range of the airflow meter!!!

I'm chuffed with the torque increase 

It's noticeably quicker which is good enough. I reckon that more can be made further up by messing about with the boost offset on the profec boost controller, so less air gets drawn lower down so the afm can keep up, enabling more boost higher up, but it would be snatchy, violent and horrid to drive I bet. Plus things were on the verge of getting too hot too quickly anyway, due to the restrictive turbo manifold.

But as it is it feels good, must remember it's the best part of 290 at the crank so can't complain!!

The next level now would be standalone, and a different turbo so I could get a tubular on there.
