212 22X .553 .553 TRUCK NORRIS stock flex fuel 5.3

Thanks for the reply, idles good at startup adj rpms to 950, Added TPS sensor to channel shows 0.00volts. Got it idling ok now, but when adding throttle it surges down, seems to be lacking something.

Hello I need some help,not knowlingly using 2 BAR, Flashed my "AS FOUND" 1 BAR P59 5.3LS Swap to LQ4 Cammed 6.0, BEE HIVE SPRINGS, AEM WB, Shorty headers, cold air induction, with CATS, beefedup...

Could I delete the MAF sensor, im a DA but trying to learn from my mistakes. What can can be done to correct bar2 back to Bar1. I do have flex fuel I used fuel rails from my old 5.3, which the 6.0...

here is other as found file from p59

here is my p059 stock read and my current tune file along with scanner deails. thanks for your assistance

I went to write my as found file back to p59 Ecu and reads different operating system. Should i reinstall donor ecu back in and try that?
Thanks for any suggestions

when i go to my stock file, and i click OS its only giving me BAR 2 and BAR 3 as options no BAR 1 im using P59 from 05 Avalanche Doner motor isfrom 06 GMC denali LQ4 6.0.
also after i fail Maf freq...

then im not sure how that was posted. although i did adjust it to 480

no, boost and yes for curiosity tried to break torque. as far as Bar I choose 2 bar since i thought it was right. I adjusted Maf Fail high 0hz also mil on 1st error. how do change to Bar 1? thanks...

I'm Adam,
I noticed when I applied the brakes and the gas it would bog down. I added TCC to my list and its staying locked besides when in neutral. what can help this? please look at my Log File ...

Truck idles ok at 1100 rpm, although when in drive or reverse throttle needs pressed to keep running. Rolling idle is 1200rpm trying different settings. Installed wide band, truck norris cam, cold...

its shown a misfire ever since it started running.

]LMAO Gmc,

Ok, thanks for the replies. Now my short and long trim on bank 1 is in the negative. Which is lean, how do i fix that issue. Also scanner is showing multiple misfires. All coil packs are firing. I...

Could i read the avalanche ecu, and copy and paste to the gmc ecu, since 2005 avalanche didnt offere 6.0 just 5.3 and 8.1? Just wondered if if there was an displacement option for the 6.0.

Will i be able to change engine displacement to 6.0 since 2005 avalanche did not offer 6.0 in that year only 5.3 and 8.1. Or could i possibly copy and paste from 05 avalanche ecu to the 6.0 from 06...

would i have to buy additional credits, to read the avalanches ecu?

Everything, although i replaced the sensors for new ones.

If id known i could, i certainly would have. So what will be best since its complicated?

Would it be best to download a file for my avalanche ratherthan using the denali even though there 2 different engines?

I didnt know, since it was a 6.0 ecu that i would use the gmc. I have the avalanche ecu, didnt think it would work since its a 6.0 now.

Ls swap 5.3 to 6.0. I have a 05 Avalanche and the donor motor came from 06 GMC denali. I installed cam, beehive springs, shorty headers, cold air intake, and upgraded exhaust.

Also rpm gauge and speedometer is all that works, and all the lights are lit abs, engine, and battery etc.

Didnt realize it had the bar 2 os, there were some files that requested bar 2, but thought i ran the one that had no bar mod. As far as 02 sensors i left them the way they were when i replaced...
