Dude ...
What the hell are you talking about ???
It would seem that your post does not belong in this thread.
If you could be more specific about what problem you are trying to solve, you might...

If this is a Race-Car with a Stick, set the Idle at 1200rpm, you may have to figure out how to slightly crack-open your Throttle Blade by adjusting the Stop-Screw, and/or,
by drilling 2- 1/8" Holes...

Did you make all of these changes all at one time ???,
Not a good plan, especially a Cam and a MAF a the same time, the other changes are mostly insignificant as far as Idle Quality goes.
Put your...

I guess the "new site" still needs some refinement,
there is apparently no "Up-Load" Button,
so, Ill post them here.

I lost my original Tune File due to a failed Laptop,
so the repository...

Just taking a wild guess......
With a choppy cam MAP and TPS will go unusually high in a low rpm / cruise situation.
What rear gear is in the truck ? Tire diameter ?
What do MAP and TPS and RPM...

I've been trying to run down this problem for a long time now,
and finally found the solution in an odd place.

First off, this is not yet another, I have Idle problems with my 312 degree cam...

WOO-HOO, I found the problem. NO MORE Random "Cruise Control".
In a place that you would never have guessed.
Engine Torque Management (Engine), of all things.

Engine---> Torque Management--->...

If I had to hazard a guess, I would say that it might be situation where the expected "calculated" airflow,
and what the MAF says, get far enough apart, for a long enough period of time, to trigger...

Very interesting, and Thank You.
I'll look into that when I get some time,
because after 2+ weeks of no problem, it's now back first thing this morning. :(

That You for replying.
I was about to give this thread a bump now that the holidays are over.
Only thing is, I haven't been doing any tuning over the holidays,
but the problem seems to have...

Thanks for replying Wayne,
It took a while to figure out how to upload, but I finally got it.

BTW, anyone.....
I can't seem to find an "Airflow" button/setting for "DFCO Airflow".
There's...

Hello,
It's not surprising that this thread is still going.
Earlier it was mentioned that there are various factory idle schemes not necessarily covered here.
Well I'm dealing with one of them,...

Sorry about the delay getting back.
I used to be a Mega-Squirt expert, but to be truthful, I'm still learning GM computers and HPTuners software.
I was basing my replies off of MY personal...

Sorry about the delayed reply.
I'm the victim of some over zealous Sheriffs deputies (blatant lairs and criminals) and just got out of jail and got my truck out of impound.
For asking a question of...

Any time you have an unusual swap, with all kinds of "I didn't know that matters", or "I was told that...", or "I know a guy who did it and he didn't have any problems", type of changes, there is...

A Wide Band Gauge on top of the dash is really, REALLY recommended.
This is a very important tool that you don't want to cheap-out on.
Just like you should be running the best premium gas you can...

I think I may have finally found the solution.
There are quite a few "testing routines" that run automatically, which are sometimes controlled by the settings in
"Engine Diagnostics" -- "DTCs",...

BTW,
You NEED a speed sensor.
They are available.
Get one.

4drz06, He's not to that level yet.
If you look at his tune, throttle follower, throttle cracker, and stall saver, are all inadequate or completely shut off.
Lots of tweaks on ALL the idle control...

Yes, You can adjust anything that is affected by a change in exhaust back pressure.
First, let me try to clarify what you are saying here with a wild guess.....
You have installed headers, and/or,...

Here Ya go......74455

This is a very interesting discovery for me.
Although, I don't think it is actually related to the VE tuning problems I've been having.
My Commanded AFR does NOT change though, and yet my Wide Band...
