I just want to make sure since this is one ecu almost NO ONE mentions when doing a b20 swap...

This is going into my 93 Civic CX. I just need any NON-VTEC OBD-1 ECU right? So I can use a Stock DX ECU or more preferably, an ecu from an Non-vtec OBD-1 Integra RS/LS/GS right?

Any differences between the PR4 (92-93 Integras), P74 (94 Integra), or P75 (95 Integra)???
Which is the best to run for best performance with a JDM B20B in a 93 Civic?

 

get the P74 if possible

 

Just curious, but what is your basis for that advice? Do you have a reason for this? I'm just curious. I mean everyone says to get the P74/P75, but it seems to me the PR4 is the same thing??? Non-vtec, OBD-1 ecu.....

Anyone???
