Roland@pcmtec Posted November 29, 2021 Share Posted November 29, 2021 I'm not 100% they have the boost drivers. Do you have the part number? I think some of the LPG ones did but not all. Quote Link to comment Share on other sites More sharing options...

Datalog your boost pressure input IBP and all of the various IBP fault codes. You can also datalog the raw voltage. Quote Link to comment Share on other sites More sharing options...

boostedfalcon Posted November 30, 2021 Author Share Posted November 30, 2021 @Roland@pcmtec i have attached a screen shot of key on engine off, 1.10v going into Pin C2, i dont seem to have any issues with boost the control side of things only with recognising the boost pressure sensor.

boostedfalcon Posted January 11, 2022 Author Share Posted January 11, 2022 replaced pcm to resolve issue, pcm would not recognise voltage input to C2 Quote Link to comment Share on other sites More sharing options...
