Technical advice needed (ECU)
Ok so a friend a I bought a facelift UK classic (T reg 99) with a VF28 turbo and Version 5 sti ECU to run with it, we went for a drive in the car, car ran perfectly, no faults obvious or lights on the dash however the engine then failed and stopped (blew up) whilst were out.
We then sold the V5 Sti ECU and VF28 turbo to a friend of ours who put it on his UK T reg wagon, after fitting the 2 items, his car would not fire but would turn over....
He plugged his old ECU (the standard one) back into his wagon and the car struck up fine.
Obviously this norrows the fault down to the Sti ECU however could the failing of the engine that we got the Sti ECU out have caused the Sti ECU to lock or stop an engine from starting, we would under the impression that ECU's off classics were plug and play, any help appreciated...

Nothing really is plug and play to get the most out out anything safely you upgrade on a subaru requires a remap. Can't see how blowing your car up would blow the ecu but strange things do happen.

you may have to swap a couple of wires around on the ecu loom. As far as I'm aware JDM cars don't have immobilisers where as the uk ones have. Also if it's a version 5 sti ecu, it would have came out of a import sti as there weren't any uk versions, so the map would be totally different.
someone should confirm or correct what i've said as its what i'm lead to believe
is he sure it's a sti ecu? what code is on the case (although cases can be swapped)

thanks for your help.
thank you

Ah not good news, are the crank and cam sensors the wires that people say you need to swap or is that something completely different? we did get the STI ECU out of a UK car???
Cheers

Sorry my iphone typing was terrible
The cam and crank sensor wiring is swapped between uk and sti on 99 but when swapped it wont run.
Throws an antenna error if I remember correct.
Besides that the engines are different (pistons, cams, rev limit due to valve train) so even if it ran its an unwise move.
You could get it mapped but obviously cost implications involved.

I think this was the very 1st question that I posted when I joined scoobynet, and was told no it won't work. . The reasons being as mentioned by JGM, some of the sensors are in different places on the ecu,sti 's also rev higher than the uk counterparts and have stronger engines. Also an sti ecu will be mapped to run on Jap 100 Ron fuel, so even if you do get it running it won't run as it should without some remedial work being done, and can lead to engine failure.
Your 99 uk turbo should have a E3 ecu(AE800/801) as STD fitment which is designed to run a td04 turbo, if you decide to Bolt on the vf 28 (like I have) then it will need a remap.
