ECU's...

Had a brief chat with Sam and Ryan about this before i went away, bascially when i fit cams, i dont want to map my ECU, and if i buy a standalone ECU im going to have to take it somewhere to get it wired/modified to fit as mine is a 3 plug ECU. Ballache.

So i was thinking, if i could get another standard vts/gti ecu and get that mapped, then i would still have my standard one incase if i ever needed it.

What do people think about that?

If i was to get a om ECU would i best getting vts over gti? I know they are the same engines but just wondering if there were any slight differences

Has anyone got an ecu for sale?

Also taking it that it would have to be unlocked?

Ryan - Email me you gimp

[leeroybrown]

Would think both ecus are the same, but again it depends on year of the car.

Yours is a 2001 (i think) so obviously need a 2001 plus ECU.(3 plug one)

Sure there is a guide on here or SSC for how to unlock ecu's.....

Can pick them up for a bout £35 for the ones i have seen.

You could also send this ECU of to wayne tell him your mods and he can put in a generic map.

But for best results i'd have it RR properly

[Toad]

Yates, buy a standalone ECU, end of problems forever. :)

My ECU has been mapped by Wayne, and the map was for 708s. THe car made the same BHP as every mk2 set up, which was 153 BHP. You can buy my already mapped ECU off me if you like. When I move to standalone I won't have any need for it. I don't really understand why want another ECU though... ???

[leeroybrown]

Cos he is a tight ass Toad and wont spend his money tbh

If you aint going for bodies there is nowt wrong with a ecu remap

You want to be different... go for standalone

True'sih... The problem with the stock ECU is that it tries to make detromental changes after the map. They're a pain in bum hole... Standalone will reap better results, and less issues.

[leeroybrown]

Depends on the cash though doesn't it


Dont think that will be a problem for our Matt though;)

[Toad]

Haha. ;)

I say if you don't have the money to do it properly, don't do it at all. But I've been through (and still am going thorugh) the joys of having a re-mapped stock 3 plug ECU and it's pony. If only I knew then what I know now, I would have never done it this way.

[Yates]

Im far from a tight arse.

Toad - Its finding somewhere that will wire the ecu to the 3 plug, with a standard ecu it will not be a problem.

Having the 2, one just incase i go back standard i have one mapped to the standard cams

[leeroybrown]

Must be the 3 plugs ones, a few on my mates have had there single plug ecu remapped by Wayne and they have been 100% spot on

[Yates]

Haha. ;)

Ignore leeroy, he knows nothing about my finances.

Im doing things properly dont worry mate, just wondering if it was worth while

[leeroybrown]

Yates GTF

Any good auto electrician should be able to wire it in

No worries mate, I know Leeroy's sense of humour... ;)

Well, no it's not worth it. GMC can do the wiring. For some unknown reason however, John (GMC) said he can't maintain the use of the oil and coolant temperatures with the KMS ECU, but you can wire those temps into the wideband display, which is perfect IMO, as you get a genuine temp readings, not just a level pointing somewhere... :A:

GMC do a thing for the single pluggers which uses the stock ECU in conjunction with the KMS. The stock ECU is kept purely for the display of the temps I mention above. IMO, get the stock ECU out of there!!! :panic:

[leeroybrown]

No worries mate, I know Leeroy's sense of humour...


Ha ha i know what your saying there

A mate of mind had nothing but hassle with his 3 plug ecu and his emerald

Dials always used to freeze and every now and then the old ecu would try and knock the car off, meaning having to reset the ecu evvery single time.

Managed to get around that though, its just choosing the best system

[williamsvts]

just get a standard ecu remap. i still dont know why you wnat another standard 1? if you ever came to sell the car wayen will flasha a standard map on for about £50 iirc. GMC do new standard ecu's for £200ish, unlocked.

both vts and gti ecu's are the same.

[williamsvts]

toad - what problems are you getting with your ecu?

Sounds like good advice to me! :y:

Williams, it's really the amalgamation of various small issues... For example, my engine check light is permanently on, as it's moaning about 1) The air injection system I took out 2) The seconds lambda sensor and 3) The ECU moans about itself, saying there's a malfunction with the ECM / PCM processor...

Then there's the way the car drives. Some days it's putting much more power down than others. The cold start is crap! When you start the car, it splutters quite badly, even worse when it's warm outside... Anyway, about 45 seconds after you start the car, the car idles absolutely perfectly, but this only lasts about 30 seconds, then it settles into its ubber-machinegun idle. I don't mind the bad idle, this isn't Wayne's fault, but the fact that it idles perfectly for a small amount of time certainly makes me wonder...

The other issue is the starting. If the engine is up to temperature, it always starts perfectly, and if it's stone cold it always starts perfectly, but if it's somewhere in between, it often stalls immediately after you start it. The revs kick up as usual, just when you turn the engine over, but instead of the revs staying at around 1000, they just fall as if it's not making any effort to tick over.

[leeroybrown]

Running cat cams!

All the one have i seen do go into machine mood every now and then

Coughing and barking.. get it some rev's and theres disappear

Aint having much luck toad are you

[Toad]

That's just the startup mate, I'm used to it now. But i've altered my cam timing since the map, and to also make better use of the BV head that went in after the map too. Got more power! :y: but the idle is shocking, lol. It's worth it IMO tho! haha ;)

Mate, this car is a burden, and it's also cursed. It's had more money spent on it that I'm ever going to admit!

[leeroybrown]

Next time get a single plugger lol;)

[jpsaxo]

GMC do a thing for the Ghey THREE pluggers which uses the stock ECU in conjunction with the KMS. The stock ECU is kept purely for the display of the temps I mention above. IMO, get the stock ECU out of there!!! :panic:

Get a single plug ecu loom, install that, then you can get a KMS loom adapter, get it mapped

Buy a single plug oe ecu when you come to return to standard

[Toad]

Why on earth would you re-wire your entire loom, just so you can use a stock ECU in conjunction with the KMS, when you can use the KMS on its own with no stock ECU.

Because single plugs rock!! Lol,

Why not?

Nah just seems alot less hassle than 3sum ghey plugs

[Toad]

I was thinnking of a bespoke loom when installing a standalone... Hence my confusion over installing a single (rocking) plug loom. ;)

[Karl]

.......why did I buy a 3 plugger? :(

[Toad]

.......why did I buy a 3 plugger? :(

Tis not then end of the world, don't stress. :A:

[leeroybrown]

I think Wayne would have mapped rather a few 3 plug ECU's by now and some of them must be running spot on...

Maybe you just have a dodgy ecu Toad

[samcook]

3plugs eat penis lol

If mine was dodgy, it wouldn't suprise me in the slightest mate... Everything else to do with the car seems to be that way. :n:

[leeroybrown]

New Year soon

New luck maybe Toad

[Toad]

Hopefully geez. Got a lot of promising things happening soon, so you never know! :y:

[Ryan]

Ryan - Email me you gimp

will do dude when im back from, uni

[williamsvts]

mine hasnt had any of them dodgy strating issues.

jp - you would need the single plug car loom and dials aswell.

Funny you say that, one in my garage Lol, complete interior single plug loom

[Steve]

whats so bad with 3 plugs?

[Dasher_VTR]

just want to know if i get my ecu mapped when i get my cams put in will i have to mapped it again when i get a 4-2-1 manifold on it?

[Yates]

3 plug ecus need to have the loom split as the ecus are one plug. hence why ive thought about getting another standard one and mapping, have to say toad you are the only one ive heard about whose had these problems.

the thing with having my standard one back home is that if i sell car or for some reason need to go back to standard, i can stick standard cams in and ecu, rather than stil run the mapped ecu, plus if it does go tits up ive stil got the original ecu.

i know that gmc can adapt the wiring to fit, just wondering whether i want to spend that much on kms.

It would be ideal if i could buy a stand alone ecu from someone, they fit it and map it, job done, was going to speak to gmc i know they can do this, but see what other ecus they may sell, price doesnt really matter, but if there is a huge difference between the two then i know id probs go with the cheaper one

i started looking into the emerald ecu, but again i would need to find somewhere to wire the ecu to fit my 3 plug then have to get it mapped, i dont know of anywhere local that would wire it in, id rather have someone who has a reputation for doing it or at least has experience, which again points to gmc lol

wait till you have both then get it mapped

If you contact Dave Walker they will give you the local sparkys number who installs all there ecu's, not far from him, then get him to map it

[williamsvts]

just go direct to emerald.

or just get your standard ecu remapeed and be over with it :P

[Ross-1987]

I really have no idea about ECU's but i am still enjoying reading this thread :y:

[leeroybrown]

just go direct to emerald.

or just get your standard ecu remapeed and be over with it

Which is Dave Walker

Emerald dont fit the ecu's neither hence why i said they will give you the number of there local sparky
