Hi,
I may have just dropped a bollock, I have version 4 sti impreza running a Esl, ecu, I've just bought a psi3 monitor it powers up but won't read? Is it capable of reading the Esl system can anyone help
Thanks olly

 

I don't think the ECU language for a V4 sti is suitable for the psi monitor. It wasn't until 1999 that the language was compatible. OBD standard. The fact you have an Esl Ecu is not the problem.

 

Thanks it looks like that maybe the case!!

 

Do you want sell it?
