My Poor Jdm GSR swap into my 1993 honda cx civic has been a strugle. So i've done 2 d15b swaps and this is my first b series. Got it in and running but throwing code Zero ( cel / Mil 0 ). Re grounded the entire motor and contacts. Tested My Main Relay, and the harness. I'm pretty sure its ecu but, i would really like to know what shorted out, and its C27 an 220 uf 35v 105 c( OR SO I THINK, Please correct me if i'm wrong so i can order the right ones right away! ). I had to order off the internet because radio shack doesnt carry them. But i'm still waiting on them. And i do believe its just the one capacitor. This all kinda happened when i was adjusting my tps sensor and i was getting low voltage so i checked the cel, and here i am.

Maybe JDM b18c Ecu Schematics anyone?

This is a JDM GSR b18c p72-003 ECU. Any and all Comments please! Cheap fixes, to sending it somewhere. This is the last piece of my puzzle.

Some of the pics are old like i did not re ground everything till the motor was in.

If you have code 0 but the engine starts and runs, then check for a short in the service connector and CEL wires.

Not saying you didnt wire it right, I would go back and make sure you ran your wires to the correct pins on the ecu. because the ecu is protected by a fuse. The fuse should have blown first. witch makes me think you are bypassing the fuse and running a power wire of some sort to a ground on the ecu. good luck bro

These ECUs are almost 20 years old now, capacitors are starting to go bad. Simply replace the cap.
