Jospeh, explain how with Crome, any time it throws a lovely limp mode my car won't even bother to crank over but Uberdata with limp mode would always crank over? It couldn't have anything to do with the fact that Uberdata actually edited the fuel table primarily and Crome just uses a multiplier as a the primary and the fuel table as a fine tuning? Go test this out and prove me wrong, because based on my experience, I'm sticking with the ECU absolutely references the fuel table on the ROM during limp mode.

As for the solid cel, if the p13 ECU runs clear with only an O2 cel, and I can't think of one reason why the wiring would need to be changed to run a civic/integra ECU. I'm still going with my list of things. Chip, rom, ECU. I'd go out on a limb and say 95% thats the problem and I see no reason why it would be any different on this occasion.

BTW: Pgmfi's wiki is horrible as far as all things ROM related. Sooo out of date. If you bother to compare the information in there to what is used now, I'd say there is enough things that are invalid to make most people second guess using it as a resource. If anything use the commented out ASM files as your reference.

 

That's not limp mode. It's code glitch that doesn't send an error to boot up limp mode.

Remove your MCU entirely, and then see how the ECU behaves.


You don't think the EGR lift sensor and solenoid have some impact? 88-89 HF are not true OBD0 MPFI plug and play for just this reason, despite interweb rumor. I've been through two Preludes now, one had similar problems but it was a couple years back + I don't remember. I get a chance to ---- with a third tomorrow that does not like it's chipped ECU, and I'll get a crash course then.

Yeah, some of us got tired of cleaning up crap after people. The ignition tuning wiki entry makes me shake in anger.

 

Can a p13 even run on p30 code

 

Crome offers partial P13 support. johncui has a hard on for P13 code, says it's structured more like a race-oriented ECU.

 

Guess Ill go try to open some of my all motor proggies I got for the p13 ecu awhile back

 

The fuel maps will make you giggle.

 

We're going to try uberdata today. I'm still learning Crome.

 

Ill stick with p30 code

 

can i ask who's car you are speaking of?? i didn't know steve actually worked on cars, just invited people over to work for him j/k
