Im doing a b20b swap on my 94 eg. Im running it OBD1. I have a p06 for it but my question is will a stock p06 ecu give the b20b enough fuel since it came from single cam d series?? Or do i need to get obd1 p75?

 

p06 will start and idle it but I would not suggest driving on it. I would try and find a P75 obd1 if you can or find a socketed obd1 ecu (non vtec) and call phearable.net (vendor here) and get a chip for $35+shipping for your set up

 

Is a pr4 the same as p75?

 

if i remember correctly the pr4 is obd0 90-91 ls ecu. it would work if you can find a obd1 to obd0 jumper

 

I also have a socketed p06 without a chip. If i bought a chip from phearable.net would it bypass my sensors too or do you know?

 

If you told them to program it that way then yes. If you dd not then no.
