90 crx usdm b16a2 jdm p30 ecu HELP!!
 

Hey all...I have a 90 honda crx si...with a b16a2 and a jdm p30 ecu.... the wiring is all screwed up...it starts...and runs....idle is a little choppy when engine is warm...it throws a code but i cant check it because i have no dlc

the harness is obd1 along with the ecu i think...
I am located in Howell/Freehold area and if theres someone who wants to take a look at it...I will pay to have it fixed!!...also any questions feel free to ask...

ur ecu should have a glass hole in it........count the blinks

If you want to get your car straightened out, give me a call.

215-962-1423.

Are you sure it's OBD-1 and a P30?
Who did the wiring?

You can check codes on those cars, the check connector is located in the engine compartment on the driver side harness.

P30 is an OBD1 B16 ECU...OBD1 dosen't have the light you should still be able to use the jumper plug to check the CEL if you were closer I'd come look at it....

reading owns me

Exactly
 

No light on ecu

Jdm Totally Square... (2/3 size)

wiring appears to be obd1 >2 conversion..

will drive <1hr to get it looked at or fixed...

:( wish i had a data link connector...but i dont :(

what are all the numbers on the side of the ecu??
