Im puttng a 98 jdm b18b in a 96 civic what ecu do i need the p75 or the pr4? Im diong the swap this weekend need to know asap ive looked around can't find exact info thanks

 

get a obd1 p75 pr4 r obd0

 

is it plug and play for the car i dont need a jumper harnes

 

this guy dosent know **** some pr4's came obd1

 

so which ecu do i need

 

Are you still OBD2 or did you convert to OBD1? You may need the OBD2 LS ECU.

Or, get any old non-vtec pre-OBD2 ECU and chip it.

 

im still obd2 using the wiring harnes from the car

 

Then get obd2a
Whats the misunderstanding. Pr4 was obd0 and obd1.
P75 was obd1, obd2a, and obd2b so be careful which one you get

 

fosho i just have one more question i was looking at the motor and when it was made. It was manufactured in 98 and my head says that its a pr4 wouldnt i want to use the ecu that goes with my head? Im goin look for a p75 but i need to now thanks
