Hi Kyle,

I think you may have emailed me about this also.

Have you done a TPS Calibration? This is under Options > TPS Setup.

hi scott

yeah ive calibrated the tps i sent u a log file i also noticed my battery voltage is only reading 10v on pc link but when i check voltage with a multimeter it says 14v any ideas how i could be losing power between the ecu

cheers kyle

Hi Kyle,

The battery voltage in your log looks very low and spikey. Possibly you have a bad ground or +12V feed to the ECU.

The following pins should have a good ground to them:

Pin 108 and pin 116.

The following pins should have +12V with the Key on:

Pin 45 and pin 49

 

You can find the pin numbering in PCLink help under PCLink Help > G4 Plug-IN ECU Installation Manual > Pinout > GTRLink.
