gte ecu in a gsi?

[dunova]

I've been told the ecu from the gte perform's abit better than that in the gsi-so i got a gte ecu and whacked it in my gsi but it wouldn't start (like it was imobilised but wasn't) are they coded or something?Will i ever get it working?Also does anyone know if they are definately better/quicker? I was told it would push my performance up by 3-4 bhp :idea:

im not 100% sure but there are 2 types, bosch and siemens and wouldnt of thought they would be interchangable.

[novashed]

ther not they have different pin arrangements!. there are different types of siemens i think, early and late

yea the gte has 100brake ecu and the gsi has a 98brake ecu

[novashed]

wot? 100 brake ECU 98 ECU???

[dunova]

So is there any way to get it working?

[Aragorn]

the GTE had a bosch ECU for 1 or 2 years then switched to a siemens one

the early (upto 93) gsi's had the siemens one too

they are not interchangable and if your GTE and GSi both have SIEMENS and WA printed on them then they are the same ECU

if not they aint and they are not compatible
