wont idle in open loop speed density

[CoolWhip09]

I bought a truck recently that has a l92 swapped into it. Previous owner told me something is wrong with the tune. I figured out they were running it in MAF only. I put the ECM into open loop speed density to tune the VVE table and I can't get the truck to idle. As long as I keep the throttle pressed the truck will run but as soon as i release the throttle it immediately dies. I'm new to tuning and i tried everything i know to try. Can you guys please look at this tune and see if you can tell why this thing wont idle? Alot of stuff has been messed with before i got it and i made some changes tuning the MAF.

Did it run in MAF only?
If so re-enable the MAF and closed loop, get a log if it running and post it up for people to see...
Be sure to log: RPM, MAP, MAF (g/s)&(hz), Volumetric Efficiency Air Flow, Dynamic Air, Cylinder Airmass, Intake Air Temperture, Wideband (If applicable) LT and ST fuel trims if you choose closed loop

change the idle airflow effective area max fail from 60 to 200, and set the engine diag airflow mass airflow sensor counts from 400 to 0, rpm from 300 to 0, enable delay and rpm from 1 to 0, fail high 2 fail low 1 see if that helps

Yea, it runs and drives in maf only. Ill try to get a log this afternoon and post it. thanks man

ill try that this afternoon after i get a maf log. thanks

Looks like you have a bunch of shit changed that shouldn't be. BRAF ECT multiplier for one. ETC scalar is another.

Your idle speed tables are all over the place.

Looks like some of the adaptives have been changed.

Need to put it back in closed loop and at least let the short-term trims rough it in for you.

Hey bro. I thought you might wanna know you were right. I appreciate the tips. I've done quite a bit of research before I started pressing buttons and you were the first one I've seen that suggested failing the MAF with these extra steps. I think the effective area suggestion is what did it but either way you got me idling. I appreciate it. Edcmat suggested a couple things I'm gonna look at too but I thought I'd ask you something else while I got u. He mentioned the ETC scaler was wrong. I swapped the throttle body for the ls3 gold blade. Do u know if the ETC scaler for that is 5,636.0000? The truck is a forged l92 stroked to 416ci, in case you were curious. I appreciate your help man, and everyone else's too.

if edcmat mentions things to change then they are worth a shot, the idle correction airflow does work well stock even when modded if the rest is setup right, im not sure on the swapping TB it may be best with the original values for original TB so it matches the airflow corrections, if it all works together then the spark has the least work to do and all ends up better
