Ok did a search couldn't find anything out about this. Just wondering does the 32 ecu display error codes when items fail? ie 02 sensors etc. As I asked at a local shop today and they told me remapped 32 ecu's will not display error codes. Is this true? If not anyone able to point me to how I can read the error codes off my ecu. I can read the errors for my attessa system, but so far not the ecu itself.

thanks.

i would not see any reason why normal diag wouldnt work on a remapped ecu

a remap is usually an edit of the IGN and INJ maps and some adjustments to the airflow protection (set it really high) and set the speed cut really high

ie: they dont edit ECU Binary code, they just change values
