just wondering if you can change the ecu in a my99 for a different one outofsay a sti of same age .like you could on the older classics i.e a z4 ecu

bigsinky

No. Putting Japanese ecus in a uk car is a nono. It has to be like for like. You can keep the ecu and add the likes of an ESL daughter board. You can use EcuTek to reprogram or you can change your ecu all together for something like syvecs, simtek, motec, apexi et al

for starters a 99 my has three plugs, pre 96 z4 ecu has four plugs.

why do you want to swop it , my99 is a mapperable ecu

demonsurfer

what sort of price would i be looking at for remapping the original ecu

bigsinky

Depends what you want to. Cheapest option I'd ecutek. 350 plus first licence fee. Simtek is about £1k while solaris/syvec is about £1.5k. Motec m400 will be even dearer. You might be able to get a motec m48 pro cheaper 2nd hand.

What sort of modifications do you have and what do you want to achieve

demonsurfer

as far as im aware there is a full ss scoobiebits decat exhaust on thats it really looking for around the 260/280 bhp mark

bigsinky

Is it a uk turbo 2000 car?

demonsurfer

yes its a my99 uk but feels quicker than my old jap wrx

bigsinky

It's a tired 12 year old engine. It was 215 bhp out of the show room. With a remap you might see 260 at a push. Bigger turbo, injectors, and freer flowing exhaust might see you to 280 - 300? But then other things start to break

demonsurfer

it had a full rebuild about 20.000 miles ago i have a folder full of recipts from the old owner of parts services such like .

bigsinky

Ok even better. New turbo, bigger injectors and a remap then

demonsurfer

yep thats what i was thinking to just need some more info on how much my standard ecu can take me upto

demonsurfer

also tempted to go ether fmic or new larger top mount intercooler need some ideas who does the best remap with out me having to sell a kidney so to speak

injectors should be fine if they are 440
to make 300/320 you will need
vf35/34
3" decat
3 port
a good panel filter or cone
uprated fuel pump
and a good mapper

and then you will need to upgrade brakes and suspension

and probably a better tmic
one of a facelift sti would be ok

demonsurfer

already got the 3" decat on
have 4 pot calipers on
1 kidney up for sale to fund this project

4 pots should be ok but need good disks and pads

you are added 100 bhp ish to the car you need to be able to stop it

demonsurfer

just finding one thats in good condition

demonsurfer

seen some nice black diamond grooved/drill discs for sale on this forum as well

demonsurfer

need to find a decent tmic from a facelift sti if anyone knows of 1 going
