WHat is the diffeence between a P30 and P3 ecu. Are they about the same. Im thinking of trading my ecu for one of these. I know the P30 is what I want exactly, but is the P3 abotu the same??

 

never heard of P3,
there was a JDM PR3-J01 (obdI), which is exactly like a USDM P30, as far as performance, difference none..redline 200rpm farther then USDM...but it has a speed limiter...

would I trade, not really...no gains, no other features either

 

i thought pr3 was obd0 out of a jdm crx sir

 

Yeah the ECU I am looking at was out of a JDM car. SO is it OBD1 or OBD0. If it is OBD0 then it wont swap with the OBD1 ECU I have right now will it??

 

nope
