Catalyst spark correction.

Somebody with more experience chime in on this part. Cooler air means more grams per cylinder, but colder means slower burn. Can't this easily...

i cant open the attachement

Zero it. No question, just do it.

Is he going to try to leave it open loop when the swap is done? That's what matters in the end. If not, might have wasted a good bit of money on dyno...

I'll look in to that tomorrow. about flex fuel sensor, i have mounted one but i have not enabled it as i feel that i have my hands full with simpler...

Yes no cats. Long tubes upstream o2s

The original in post 1 was tuned on the dyno with wideband.

Did I read "no catalytic converters"? If so, zero this. That's from the "original" file by the way. Didn't open others. Slow mental day...

Im not seeing the parameter to prolong pump prime or the delay timer between primes. I may have them on a xdf but not the first one i opened.

I suggested zeroing out certain things that may point towards idle air. If you get to the "unplug MAF" part and it runs the same as before unplugging...

Thought it was turned back on by now. There was talk of DTC reporting. Fail on first error and what not.

I have been reading nonstop since this started and I’m starting to think it is in the friction airflow startup initial and friction airflow initial...

And i don't think you want to fudge this number like I believe somebody has. I believe trims will target an O2 voltage and this fudged number...

When I asked him about MAF, he said it was turned off and tuned VE. PLEASE keep in mind I’m very new at anything tuning. Everything is in stock...

+20-25Hp is the most we see on those

And nobody asked if MAF is in stock location or jammed against throttle body.

I've never had a fan not work because of a DTC wasn't enabled but I have seen other things like flex fuel sensors won't work until you enable...

If MAF reads lower than actual, and you just wrench the VE up in open loop, commanded AFR would report rich. It'll read low if callibrated wrong or...

I solved few issues of this nature - let me know if you want professional help.

Hello :), Came from the garage just now and no PWM what so ever, just a strait line at 13.x volt. tomorrow i'll bring the tone generator to check...

Thanks for this! Also big thanks to you and Murfie for the discussion back and forth. Very beneficial! I was able to use the new quadratic to...

@eric@hptuners How long before we get as patch for Gen 1 ecus? Need one deleted for a project i'm working on.
