[Mk2] [Turbo] !!! REV2 Turbo Mappable ECU !!!

[TUBBY-DEUCE]

good stuff, really glad this hasnt just fizzled out, great work to everyone involved

[Gersen]

Ryan, with this is there anyway of getting a generic map that sorts out the Rev2's habbit of just chucking fuel in after 12psi without a rolling road session, it would be nice to be able to have a safe map like the toyota one that is flexible with mods but not OTT like it is when over 12psi, or is this something to stay away from?

Cheers
Phil

Hi Phil

The short answer is that as soon as you make mods to the car you aren't gonna get safe+generic.

As we have proved on the RR even the Toyota map isn't safe when you mod your car! We got lots of det.

If you change your fueling and ignition advance without monitoring knock, AFR, holding loads( and knowing what you're doing then you risk killing your engine - either through running lean and causing det or burning the top end or causing det through ignition timing.

Bottom line is that, yes you could have a generic map for modded cars but it would be Russian roulette (probably with a semi automatic!)

excellent news shame I have a rev3

23rd run????? Man that car got a pounding lol

23rd run????? Man that car got a pounding lol

Like I said...a thorough test of the hardware and software!

[AdDaMan]

impressive stuff this... any news on an eta for the general market or a rough price? is there much more testing to be done?
unbeliveably impressive though...A* all round!

worth a try

IF YOU HAVE A REV 1 or 2 AND ARE RUNNING ANY MODS OR INCREASED BOOST THEN YOU HAVE A MASSIVELY INCREASED CHANCE OF DETONATION OCCURING AT LOW RPM AND HIGHER LOADS WHEN NOT AT FULL OPERATING (MEASURED) COOLANT TEMPERATURE – IE 3RD GEAR ROLL ONS FROM 2000 RPM!

Sounds pretty much useless then , as many people are running atleast 1bar

Well, firstly thanks for both of your gauche, nescient and above all insulting comments. You have managed on two occasions (your first and second posts in this thread) to incite me to a level of honest fury by suggesting that Jeremys ECU is worthless and that Ryan mapped it poorly.

The car came in on the standard Toyota map knocking all over the place and left with no knock and vastly improved fueling.

A bloody fantastic job (IMO) by both Jeremy and Ryan

You're clearly a genius. Why don't you read what you have surprisingly (difficult, I would imagine, with your head located where it is) managed to quote accurately?

OMFG he's right! I said....well it's right there – at the top in quote marks. Again for those at the back? Okay then.

Did anyone think I was talking about Ferrari owners? No…okay then…clearly I was talking about cheese graters? No I’m fairly sure I wasn’t. Was it the moon landings? Damn – how will I figure it out? Hang on….was it Rev1 or 2 owners (warmer) running mods (warmer still) and increased boost (getting toasty) with a standard ECU (red hot baby)

And to refer to the first post you made (which incidentally I refrained from replying to despite the fact that I would of happily thrown a piano at you as I read it and refrained from on the grounds that I bothered to read all of your posts to determine that you were presumably a Rev2 owner rather than a cheap skate ( I have now reassessed this btw) or troll’er)…..

By your comments you have defined £400+ as a specific figure that is "too much" – clearly you can tell me of a plug and play mappable ECU for the Rev2 with datalogging that also removes the need for other aftermarket parts to control the speed limiter and changes to speed sensitive power steering, AC idle up and fuel cut defencer?

Quickly now so we can nip out and buy one? Holy crap you are right! All the people making ECU’s for more than £400 have just gone out of business because it’s too much.

I’ll call Link and Motec now.

Thanks again for the comments and I’m soooooo glad that this is all “pretty much useless”.

I leave now to grind my teeth and kick puppies while the anger subsides and I plot how to get scorpions to lay eggs in your ears.

[Note - I have no involvement in Jeremy pricing his ECUs and this isn't to suggest any pricing but I recognise quality and how it relates to price - hence I have a Berk Intercooler in my car not an XS power one which would of cost me considerably less - in the not too distant future Jeremy will be pricing his ECUs and I'm damn sure than demand will outstrip supply]

Pirates comment looks like he thought you were talking about the plug and play ecu not the std maps on the modded cars.but even so he should actually read whats been written then he wouldn't look like a muppet for saying what he did.

I must say i cannot believe how good this product is and if or when i have the funds i would be at the front of the que.

Top work to all involved

I wonder how much the detonation being seen is down to using using lower octane fuel than the cars were intended to? i.e if we ran higher octane fuel would the detonation disappear or would it just be reduced?

Some reduction is the answer I'd guess. I'm not really prepared to put race fuel in a standard car to test this however!

Jeremy brought up an interesting point last night which was wondering if my cam gears had shifted at all (timing is driven off a cam). I'll be investigating this shortly.

The car was running 99 octane from Tesco on the RR - plan is to have another map for standard 95 octane fuel so I can switch for trips on the continent etc.

I have also calmed down now

I've removed my Unichip so I'm ready for my new ECU now - pretty please

[TUBBY-DEUCE]

I've removed my Unichip so I'm ready for my new ECU now - pretty please

have you noticed any noticeable difference? just curiouse

Well ever since the Unichip was installed the engine would feel very hesitant when it was cold. That's gone now.

Other than that I haven't noticed much because I've got a coolant leak and don't dare drive it very fast until it's fixed! The Unichip did seem to give a bit more power and better power delivery but it was never quite as impressive as I'd hoped for.

[dex]

Well, 99 octane is only one point difference so it is not that much but I don't know how much timing you had to pull. Something you can tell us?

O stop your trolling you I've seen the car (pre-RR though) and I can see how much work / time / skill has gone into this ECU.

Stop muttering about things you don't actually understand.

[Edit] And get an ECU sorted out for a rev1 Jeremy

Hi
Yes we had a busy day at SRR and I learned a lot about what needs to be done to improve the mapping GUI.

At the moment the system only allows access to the main fuel and ignition maps.

There are other maps eg warmup maps and air temp correction maps and an injector scaling factor to allow access to.

There's a 3D ignition table for rpm vs coolant vs ignition correction for lowish engine speeds. It looks like this needs tweaking to prevent some det if the engine isn't fully warm.

Lots of work still required...

But the good news is, the basic tuning GUI ran faultlessly for the whole session with no hangups etc.

I do need to look at ways to make it work better with USB to serial cables as we ended up using it on a laptop with a direct serial connection.

I'm adding datalogging to the tuning GUI to allow data to be stored and played back, eg if a power run is done it should be possible to dump data to a file and read it with a viewer program whilst the tuning GUI is still running. Ryan said this is essential to have as it speeds up the tuning process.

Thanks again to Tom and Ryan and Charlie for their help on the day.

Hi there,

Any progress on this recently? Sounds absolutely brill!

[Gersen]

On the final testing we are waiting for someone (me actually) to get a new turbo fitted so we can back to the RR and test the car without any blow by oil polluting the intake charge.

I now have a turbo and new studs, gaskets and the like but I am currently writing this from a (very boring) conference in France so I haven't had a chance to fit it yet.

Should have it fitted soon and then it's back to the RR!
