can i just plug up the 92-95 obd1 prelude ecu on a 1997 obd2 lude. and what is different in the two, and will any complications arise.

 

you need to buy a conversion harness from OBD2<OBD1 or matter of fact try it without a conversion harness

 

also the obd1 4th gen ecu uses different sized injectors (peak & hold) while 5th gens have saturated.

i don't know if that will affect the fuel maps but i'm sure there are ppl out there running 4th gen ecu's in their 5th gen

 

preciate the help, but yeah it will affect my fuel map, however i'm not running stock injectors anyway, with a piggyback
