here is the deal i have a b16 and i converted the wirering from obd0 to obd1 the only thing i didn't convert was the injector wirering / injectors but i converted that now and removed the resistor-box using obd1 injectors.. i tried using my brothers b17(gsr)ecu and i dont get a code 20 but when i use my usdm p30 ecu i get code 20 and it hesitates at 2,000rpm,,any sudgestions?? any input is appriciated

 

whats the definition of the code i dont have a manual handy. was this a dpfi car ever?

 

YES IT WAS DPFI I CONVERTED IT TO OBD1 LIKE5 MONTHS AGO AND I FINALLY DECIDED TO REPLACE THE OBD0 INJECTORS AND REMOVE THE RESISTER BOW.. THE CAR NEVER GAVE ME PROBLOMS BECUASE 8I WAS RUNNING IT OFF MY BROTHER'S GSR ECU FOR A WHILE BUT WITH THIS USDM P30 ECU THAT I JUST BOUGHT I GIVES ME THAT PROBLOM AND IF I PLUG IN MY BROTHER'S GSR ECU,EVURYTHING WORKS FINE.. IM GOING TO TRY THIS USDM P30 ON MY BRO'S CAR AND LETS SEE IF IT THROWS CODE 20.. I HEARD THIS PROB WILL BE FIXED REPLACING THE FUSE BOX UNDER THE HOOD ,BUT ITS STRANGE THAT IT WORKS FINE WITH THE GSR ECU AND NO WITH THE P30 ONE BTW CODE 20 IS ELECTRICAL LOAD DETECTOR...THNX

 

Damn, stop with the caps please, and the screen door typing, thanks

Maybe that gsr ecu doesnt have an ELD, is it a jdm ecu?. I know the usdm 94 gsr has an eld, I'm not sure about the b17 though.

Troubleshoot it^^^^
Or you could try just replacing the fuse box (under hood) the ELD is part of this fuse box.

 

sorry bout the caps what is "screen door typing"??thnx for the info btw the gsr ecu is usdm

thanks for asking most folks dont care, or take it as an attack.

The text fills the entire width of the page without paragraphs and punctuation, it makes reading the post way more difficult.

Back on topic you could try putting another p30 (if you have access to one) in to see if your ecu is acting up. Its fairly odd that one ecu is okay and the other throws the code, but hell maybe someone will chime in with an explanation for that.

I gonna take a wild guess that nothing is interchangable without some rewiring and other mods.

 

if its obd1 just chip the ecu with a stock program but remove the eld function.

 

i don't want to thread jack, but starting a new thread just to ask what eld is seems a little ridiculous. so what is eld?

electric load detector, it increases your idle to account for increased electrical load


btw most questions like this can be answered with a quick search.

 

I found out why i got code 20 .... The wire from my stock harness was cut when i did the DPFI to MPFI swap .
But i wired it up & no more code 20

 

what did you wired up exactly? im having this same issue.
