Guys I've set this code twice today while tuning my VE. Luckily I think I found the fix within the tune.

In HPT - Engine Diagnostics/General/TPS/Calculated Airflow vs. TPS vs. RPM Table.

I captured one of the code settings in a log. Appears I upset this table and threw the code. My RPM 3782, 89%TPS and had a Dynamic Cylinder Air # of 1.12. Max for that cell was 1.02. I am assuming the table is in Dynamic Cylinder Air??? Only thing I can find that is close for the Airflow numbers.

Anyway does anybody see a problem with just multiplying the entire table by about 15% to fix my issue?

yeah its like a sanity check table that sometimes needs to be adjusted especially in boosted applications.

i doubled that entire table. then ran into it again later and doubled it again

LOL - Showoff! The heck with 15%, I'm going 30%!

In boosted applications like Foff said,that will happen.Increase those values.

Strange that I haven't run into this until now. There have been times when it would buck and make the noise like it did when it set it today but it never set the code.

this is a real pain in the *** code if you have a high stall. with the stall i have now the truck will still move but with the stall i used to have it wouldn't rev high enough to even get off the road.

Mine didn't like it at all. The REP set and before I could get off the road I ran into a red light. It had trouble idling... AFR went wayyyy lean and it died. It wouldn't restart. Luckily I was able to coast it into a parking lot from the light when it changed.

I could see it not moving the truck at all with a high stall.

Being that I am getting ready to go 2Bar am I safe in assuming that I should up that table some as well? One time I had my truck do exaclty what you were describing I think anyway. Under a moderate pull it all of a sudden fell on its face completely and briefly flashed a check engine light, would not accell at all for about 5 sec. then it seemed normal. When it did this I made a wierd noise as well. It scared the **** out of me, thought for sure something broke however this was like a year ago and it has never duplicated.

Probably wouldn't hurt to go ahead and up the table. It's useless anyway if you aren't using the MAF.

This code did not reset itself. Dunno if it would have. Luckily I had the laptop with me and could read and reset it. Otherwise I would have been thumbing a ride home. Once the truck died it would not restart.
