It is a 97 del sol with a OBD1 GSR in it and im wonder what ecu i would wanna run OBD1 or OBD2 and i all ready know i need a jumper harness

 

get an obd1 p72 or any chipped ecu to run the p72 program

an obd2 will run it too, but you will have to bypass the ckf

 

what is the ckf

 

crank sensor that doesnt exist on obd1 engines

 

Its an obdII function, just go with a obd1 ecu man

A ckf sensor stands for Crankshaft Speed Fluctuation, This sensor is mounted behind the timing belt sprocket on the crank, and used to closely monitor the speed of the crank to detect a misfire etc. Only fitted to OBD-2 systems.

 

thanxs ooh and weres a good place to get jumper harnesses
