I would start with a stock VE table. If it starts and idles with that cam i would follow the guides and adjust for idle airflow. This is the base number everything adds from. (Google Russ K RAF) ...

I have been running a tune from an 01 Tahoe with DBW and a 4l80e segment for a while now. PCM bricked and I bought a reman PCM that was from a 2002 Escalade with OS 12209203. I am trying to find a...

I have a PCM i have been tuning for years with the same tune. Upgraded to 3.4 and somehow bricked my pcm. Swapped to a mew PCM, licensed it and magically was able to read the file on the Pcm and...

here is the tune in case it helps

slower I understand. but this feels like one side of the exhaust isn't connected. its stumbling to get up to speed and rocks the whole truck. never happened before I had the new trans swapped in.

I swapped in a 4l80e, did the repin for the trans harness, added the ISS, and segment swapped the 80e tune into the existing 60e tune i had. Now truck is slow to accelerate. Is this common? Is...

Not sure what fixed it. I pulled the harness and went through every wire. Retaped everything and checked resistance from each wire from the sensor to the pcm. Everything checked out and i retaped...

Replaced the crank sensor and ran new wires from the pcm to the snensor and it cranks and fires right up every time now......except if it is vacked down the driveway. Once it hits the curb it shuts...

That wasy first thought as well. Ive had this pump for a while. In fact i had a similar condition in the past and found that the hose between pump and the pickup split open. But with that i had...

I just ran out and flashed the original tune to the truck and tried to start it and no dice. Same thing.

I have a 01 5.3l DBW with a z06 cam. Motor has been running fine except for recently it decided it would like to die at random times. Once it does this it will crank over and not restart. I tried...

Thats the answer i was looking for thanks. I was thinking i was missing something in my diagrams or something. Egr it is.

I have read numerous threads that say i need to log wideband data through the AC pressure switch/ sensor. It is supposed to be a red/black wire? So which wire would that be for a 01 tahoe? I have...

I have a 01 tahoe 5.3l/4l60e that i swapped into my 79 c10. I was wondering if i should start tuning with my 01 base file or if it would be better to start from the ls6 base file. My buddy even...

I have a 79 silverado with a LM7 tune and i was able to upgrade it to the RTT and tune as i went. My 06 4.3l does not have this option available. Anyone know when the RTT will come out for the 2006...

its actually almost the same size as the top of a can of carb cleaner if you wrap a little electrical tape on it. Free plug for me.

I did some spraying with the brake cleaner and it idled up really high near the passenger side of the manifold in the front. I tightened the intake bolts up about a half turn and it settled down a...

Well i guess no one has any ideas either. I will post up here in case someone else has this issue maybe i can help them.
I did the idle relearn procedure and it seemed to work pretty well. It is...

So Desired IAC position starts about 210 and slowly goes down to 0 then the motor surges. The IAC position is steady at 310??? I didnt know that DBW trucks had IAC?

Anyone????

logs

So i loaded the RAF defaults and scanned it twice. I would have went longer but i revved pretty high and i wasnt going to check to see if it would come down. I noticed that the IAC counts were very...

So i just reviewed my scan again and i noticed that during the surge of idle my tps was up to 90%. I am not sure what this is....i guess maybe my pedal is bad or maybe the tac?

I thought i read somewhere that the DBW systems have to be at around 3% during idle. I will look into adjusting that and see what it does. I let it idle for about a minute and it steadied at about...

I let it run a little longer and it settled back to 1200 but then a few seconds later it surged back to 2600. The last thing i did to it was let it run it has been sitting while i have been finishin...
