STI V1 ECU Difference
Hi All, I have a STI V1 Jap import number 63/100
Had problems with my ECU failing a few months ago, I managed to buy an ECU of a guy on here, same ECU type SA
Its now all running, but not sure its running how it should be, looked inside my original ECU and found it is missing a chip compared to the replacement ECU..... Does any one know what this chip does??

the sa ecu should have the chip in it from the factory the chip was a way of remapping the early ecus, what boost were you running before and what boost are you running now? as it may be the case that the original chipped board was swapped out for a standard one from a wrx.

Cheers stu and my94wrx.....
not realy noticed the boost has changed, still seems to be about 1.2 Bar, think like you said last night Stu get it tested by a mapper to see what they think
Have had the car since it was imported so hope the ECU board was not changed, just very wierd.... cheers for info..... just need to save for an Apexi and mapper fees
