Running 14.2 then going rich when the IAC drops out.

Not much help.. this is why I don't post here. I'll figure this shit out on my own.

Here is a more accurate post of this issue, I am thinking startup and friction air flow

I have been given some advice to increase the camshaft rev delay values on that table under friction airflow. They are still stock at the moment.

I am posting this in response to my other post, this is more accurate and a vid.

Setup:

6.0l with a decent cam
2002 LS1 Fbody 0411 PCM
T56 6spd manual car

Here is the issue:

This is the tune file here.

I would have to post a vid of this happening because my wideband is setup to my scanner, if I emailed the log, no one would see the wideband. The commanded AFR does not change the whole time when...

I'm thinking afterstart enrichment.. fuel pressure stays at 60psi constant, regulator is fine.

"Year , make , model , tune, log?"

Literally at the top of my post.... why I don't even care for...

Doubt it

PCM: 2002 GM 0411
Engine: Cammed 6.0l
Trans: T56 6spd Manual

I have everything dialed in on the car except for this one issue. When you leave it parked for about 10 min or so, enough to where...

Fixed...wont let me delete the post so I'll fill it in..

Increased base running airflow about 40% over dynamic flow at the idle rpm I have it at. After doing that and touching the throttle cracker...

Thanks guys I'll have to check it out. I had it out yesterday, got the timing at idle to hang around 15*, matched the PID tables to the stock 2002, I'll have to check into the other stuff you all...

I've been chasing this issue for a long time, everything else seems to be fine. After driving the car and parking it for 10 min or so, you start it up and go to drive, the car seems to low idle and...

All that stuff is set to zero or no adder..only thing that can really be attributed to it is the Cam overlap....car runs perfect other than a slight bog coming to a stop, I'm attributing that to the...

This is a 2002 LS1 Fbody 0411 PCM

I'm tuning on a 5.3l, Hotcam, LS6 Intake. GM 85mm MAF, everything seems to run prefect except the idle, wants to idle at a 13.8 AFR in closed and open loop.

I lowered the idle cells on the VE...

It has a FAST Intake, aftermarket Throttle Body, and Long Tube Headers with full 3" Dual Exhaust. Next time I'm around the car I'll have to log data. Dynamic Air is pretty much onpoint with the RAF...

I'm tuning a 1999 Corvette M6. Light mods on it. When the AC is off it drives perfect, turn it on and the RPM's hang when you go to shift gears. IAC counts go up when the AC is on only, barely do it...

My next step is to try a Write Entire with a stock 1999 Corvette File and start over.

I'm working on a 1999 Corvette, LS1, FAST Intake, Long Tube Headers, TPIC 90mm Throttle Body. For those that are not aware these are factory Drive By Wire Throttle Body cars with a TAC Module.

I don't know about that..I had my 1999 Sierra updated to a 2001 calibration using a Tech II, and was able to tune it without buying credits.

But like mentioned if Kyle here has the fancy stuff it...
