ive got a 98 uk 2000 turbo i have got everything i need for a remap but was told i could use a wrx or sti import ecu and it would up the bhp and then get a remap to get more out of it also look at the turbo to see what was on her td04L what dose the L stand for ?

well a 98 ecu (uk or import) can't be remapped so you will need a complete replacement ecu.
Not sure of what the L means sorry.

could i use a sti or wrx 98 ecu import to take it from 215 bhp to 260 or 280? was told that the import ecu dont have the imbo on it would it work for a cheep up grade for now and then get it chipped if it cant be remap?

Think the L indicates its front entry, as there are TD04's with the side entry.

I may be wrong, but I think some of the UK ECU pin-outs for some of the engine's sensors may be different to the JDM cars, therefore the loom for the ECU will be wired slightly differently.

Anyhow, in the case of the JDM WRX MY97/98 the ECU is mapped for its different VF22 turbo and larger 440cc injectors (your UK Turbo 2000 has a smaller TD04L turbo and 380cc). Similar story with the STi - the MY97 had a VF24 and 440s; MY98 had VF23/440s...

cheers people so i take it i need a bigger turbo and injectors before i do anything else then dam it so i got the up rated fuel pump and plugs and air filter is their anything else i would need to up it ?would i still need a chip or piggy back to help it run or would the ecu be ok with the turbo and injectors ? never thought it would be so hard to up the bhp lol frist time ive ever own a turbo its alot to take in at once just want it to run better and faster so i can keep up with my mates 97 sti

The import ECU will be mapped for Jap fuel (high octane) so you might get bad det with the fuel available to you. The 98 ECU is also not currently remappable. I think the best option for you is to get an Apexi Power FC.

Get the Apexi and have it mapped, you will see a power improvement from that alone. You can then upgrade injectors and turbo later.

thanks will look in to it today any idea on the a price of it or is it just a case of shopping around and if i went for a td05 and 440 or 550 injectors would i have to up grade anythiing else to get it all to run together thanks for eveyones help proberley would have blowen it up by now

i know exactly what you are thinking of doing (i was going to do the same) was advised against it. uk heads and sti heads are completely different ie cams etc. the map on the sti ecu will be set up for a different turbo/440 injectors and different intercooler. you need to swap over 2 pins from the plug that goes into the ecu and move the fuel pump one. (you need to swap these pins even for a apexi aftermarket os simlar but the mapper can do it). send a msg to jgm or talk to a mapper and they can explain exactly why its a bad idea. if you still want to do it i have a sti ecu/injectors that will fit your car you would just need the intercooler and a vf22.
Yuo can't map or chip a 97/98 version 3/4 car at this moment in time so you have to buy an aftermarket ecu (i know cost) but it is so worth it.

Not strictly true. The OP hasn't made it clear if his car is an MY98 or MY99

i've tried what you are thinking of doing with a 75 ecu, the trouble is uk cars have immobilisers built in.
the car i did would not even start with a different ecu on it.

tomo72 you need to move the fuel pump pin in the ecu connection plug, as well as swapping the cam and crank sensor ones over.

so it is possable to use one then whats the difference in the uk 2000 98 heads and sti heads is it a straight swoop or two much mucking around with them

there is too many differences.. the heads, valves, cams, pistons, turbo, injectors, maf..

you may as well sell up and buy an sti
