Re: WTF is going on? **update**
 

I guess the biggest problem with this car is the wiring. It's the jdm H22A engine with the matching P13 ecu, all tied together with the stock 93 dx harness (and a couple hard wires). Would it be a definate ecu issue if it's a solid cel with the crome ecu, and a "checkable" cel with the stock P13? I thought so, but then again all of our map changes are working correctly.

Maybe we'll try a different ecu and see if that helps. Oh, and is the P13 chipable? ???

Try advancing the timing a few degrees where it starts to misfire. We had the same problem with my buddy's civic. AFR's where fine but it would sputter and misfire. Advanced the timing a couple degrees and it fixed it. Try it and let us know what happens.

solid cel=bad burn or bad chipping job


codes=bad sensors/bad wiring

It starts breaking up about 4500. Is that where you have vtec set? probably not but it could be a problem with the vtec conversion.

Um it could be the scaling for the map sensor to. If your using a gm sensor. If so put the stock one back on and try it. But probably not because if that were the case it would have normal cel not solid.

VTEC is set to 5200-5400, IIRC.

Re: WTF is going on? **update**
 

I don't know what IIRC is, but we're going to chip the original P13 as per my JD consultation.

Sweet. Is chipping a p13 the same procedure as the p06?

He has a solid CEL. Thats why he can't rev without misfiring at 4500rpm. Why are you guys making this complicated? OBD1 doesn't have seperate limp mode tables from what I've seen. They just take the stock fuel maps and multiply them by some number and it makes the car run crazy rich. Thats why he can edit the fuel map and make it run better. Just fix the solid cel and tune the car. Tuning a car with any CEL is a bad idea.

Inqy, you are an idiot. Disregard everything this guy says - he's bright enough to make it sound good, but obviously lacks all the cards AND enough experience to have informed perspective.

There is a back up MCU that contains preset tables that allow you to run off only TPS and TDC sensor. This is covered in basic ECU FAQ @ pgmfi.org, there is no excuse for you looking anywhere else for Honduh ECU information, and there is no excuse for not covering your basics. Spitting made up ---- out of your ass is no way to win the adoration of 16-17 year old boys. ::)

Furthermore, CEL 0 = lowered revlimit aka crisp rhythmic fuel cut. Misc ignition breakup causing engine to run raggedly is not lowered revlimit/fuel cut.

Stealthnigga can manipulate AFRs = ECU is working on some level. Solid CEL in this case = misc wiring or code fuckage, zero problem with socketing.

Re: WTF is going on? **update**
 

well jd makes sense that it could be map issue because he can change the afr,s( i think its just in his head) but
when you ---- up a chip job you can only rev it to 4.5k. if it works with the p13 and afc then the wiring cant be bad.

i say its a bad chip job just because steve sucks at ecu ----.
