Does anyone have a pin out for a MK1 ECU I have searched the net and I can only find a MK2 one.

Have you tried redlineGTi?

We never got the MK1 GTi over here in NA

Yes I have seems to have people asking the same question but no answer

I may be able to help out a fellow Kiwi... I bought a genuine Suzuki workshop manual off the net for a Mk 1. I gave it to a mate of mine who has a Barina GTi. I'll ring him and get him to check if it has the ECU pin outs...

Great Thanks

I am going over to photocopy the relevant pages soon. I'll post the pin outs here. I'll post the photocopied section to you if you pm me your address...
