will the JDM ECU P30 010 and the USDM P30 a00 work the exact same? its going on a JDM B16 from a CRX

 

Either will work just fine for your swap when running obdI. There is also another jdm version of obdI ecu which is also the same, the PR3 found on 91-92 model integra's, i have one myself.

 

ok cool. the 010 was the one that came with it and that ecu went bad. i got another one thinking it was a 010 but it was a usdm a00. ok im glad this will work. thanks!

 

the USDM version is worth significantly more.
You may want to sell the USDM version and pick up another JDM version.

There are slight differences, some sensors and slight fuel/ignition map changes.

Why is that? I have 6 different ecu's here, and have played with them, i can't tell any difference in performance.

I do believe the is a slightly different map for the jdm model because their B16A makes 10:4 compression. The only other difference is that the ecu has a speed gov at approx 112mph

 

USDM version was produced for the 93-95 DelSol VTEC... only.
JDM version was made in 91-94 (yes they are one year ahead) in several different cars and those models were more widely produced.

Cali people with B16s NEED this ECU or a PR3 to pass emissions testing.

the differences would be due to the higher compression, and less emissions regulations.

But really, the differences would be more noticeable at WOT and probably only dyno evident. (unless your butt dyno is calibrated really well.)

 

i think the jdm version went up to 95..my jdm b16 swap came with a p30 and the place i got it from wrote 95 on the ecu..
