Thank you for the input. I will give that a shot.
1999 TransAm LS1, 4L60E TransGo HD shiftkit, stock stall.
I am doing a sanity check for this transmission. I am not sure if I have burnt it out or if I am missing a parameter in the tune. It is...
Issue was a stuck valve above the TCC Solenoid. Repaired and it works as it should now.
Most recent scans.

Last scan, at the end the car was in D and I applied the brakes until the rear tires stopped, which stalled the engine.

Valve body is back in but still having the same issues. I am going to run it on jack stands and let it warm up fully and see if anything changes.
Thank you for the input! I do have the valve body out and will be checking the TCC and PMW. Here is a link to the LS1Tech thread where we have been talking about it.

This is not a tune issue as much as a Transgo install issue. I am posting this more for reference and the off chance it will help someone else down the road.

I was thinking that myself but just couldn't find it. I will look harder. Thank you!
Soooooo, I have an NGK wideband and I have had it installed for a few years. I have changed the sensor a few times and have just recently changed it again. After the install everything worked as...
It was the MAP Sensor. Replaced it and everything is back to normal.
That's half of what is making this so hard to track down. As soon a I shift to Park or Neutral it correct its self. Timing jumps back up, Boost drops to vacuum and idle raises back to 900 -1,000...
I didn't think so, but I figured I would ask. I am swapping out the Map sensor and will also check for any weird vacuum leaks. At lease I am not loosing my mind.
This has been kicking my but and I would like a fresh pair of eyes on it if possible. When at a stop sign my boost will raise positive and my timing will drop to 0.0 the idle will drop down to...
PCM rationality test ie p0121 is set to Min of 0 and Max to 100 but I am still getting the code. Is there another table that I should be looking at? Only other code I get is the P0742. The Car runs...
I am having code p0742, TCC system stuck on. From what I have been reading its referring to the computer determining that the torque converter clutch is staying on when it is commanded off. And its...
Oh yes, I havent touched it. I was just wondering how it worked. Trying to understand the big pictures even if they wont apply to my tune. Thank you for the warning though. I will keep reading I...
For a FI setup would this table (Desired Throttle Area) help or hurt? My BARO is 15.149, and I am wondering if I can adjust this table to quicken my Throttle Responce? I have the stock settings(3%...
Where do I change that? Or fix that? I have no Idea why its Linear. The only reasion its KPA is because I have it subtracting from the BARO sensor.

I am getting that...
Yes, it’s for a 2005 Chevrolet Cobalt 2.0L SFI SC, I think the thing I have wrong is the PID's. I have a Mechanical gauge that won’t read until I am very deep in the throttle. And to my...
Well as for the Throttle responce I filled up the tank and it was warmer out then on my way to work and everything worked like a charm.... I am thinking I will see this again when I need gas.

When your PE kicks in it will drop your AFR richer. So if you put your Stoich to 14.63 and you set the PE to 1.13, you commanded AFR for WOT will be 12.95. I have my LS1 Blown so I have my PE Set...
When you get your first scan post it up. Also your .cfg so we can read it. Good luck on the tune.
