I have a obd0 pm6 that is socketed and tuned using TE. when i start the car it throws a code 0 which is bad ecm/ecu. should i start by installing a chip with another copy of the tune or look for some type of other symptom

 

chip backwards?

 

also lets get a pic of the solder job u did on the board

 

what those guys said +2

 

How about bad burn? Maybe forgot to erase the chip before burning to it too.

 

if you have a chip backwards it wont even start...its a bad burn dude...if not then its the ecu cause whoever soldered it in pooched it.
