I have a 1996 civic with a 1997 LS swap. im running a 1999 SI harness and i dont know what kind of ECU i should run. i have a P2E wcu out of a civic DX and I have a P75 ECU out of a 1997 Integra but neither of them will work. my injector wont fire right if at all. does anyone know what kind of ecu i should be running?

have u tried the em1's ecu??? or even a gsr

 

try a p74

 

whats a em1's ecu and isnt a p74 the same as a p75. i know i need a obd2b ecu out of a 99-0 but i dont know if i should get a d series ecu or a integra ecu cause i need one that dosent have the crank position sensor cause my harness dosent have that. i am going to try a 99-00 civic dx ecu and a 99-00 integra ls ecu. butdoes anyone else know anyone who has done thi s swap and know what ecu they used so i can be sure i get the right one.

 

anyone else?

 

anyone that has done a si swap?

 

Integra ls = p74

the p74 is for a manual tranny and the p75 is for the automatic

 

is there any difference between the 96-98 p74 obd2a and the 99-00 p74 obd2b ecus? cause i was told OBD2b has 2 pugs for the harness and OBD2a has 3 but the P75 I have ony has 2 plug spots for the harness and on for the automatice plug and im positive it came out of a 97?
