Thanks for replying
A flashing MIL at idle with no DTCs set could be misfire at idle. Anytime the MIL starts flashing means the engine controls have "decided" something (in this case perhaps misfire) is causing...
In the last six or eight years, because of the nature of my work as a technical writer, I've spent some time evaluating some of the tuning courses out there.
My favorites are:
Greg Banish's...
Did the problem with off-idle "abruptness" start after you went to a ported throttle body?
Elsewhere in this forum is a very good, but very long discussion of Gen 4 idle and light throttle...
What is the source of the statement, "It is good to mix e85 with a bit of quality toluene"
I ask because, while toluene is indeed an antidetonant, it also affects burn speed...makes it slower. Not...
Whether or not it's going to be "simple" will depend on how modified the car is. There is no "stock" tune for a C6 auto with 3.42s and different tires. The only solution I can suggest, is flash the...

I recently had the "disappearing WBO2S" problem, too. I run an Innovate LC-2 and have it connected direct to the serial port on my Toughbook runnin Win 10 with the latest updates. I've used this set...

For a long time, I've wondered about a seemingly contradictory observation I have about the proportional and integral idle corrections.
With the proportional idle table.... [ECM] 12196 - Idle...
What year is your ZO6?
Just looking at spark in the calibration you posted and seeing that the high octane and low octane spark tables are the same, I'd say whomever wrote your existing...
A good starting point for calibrating a modified LS7's idle and part-throttle driveabiilty is a thread elsewhere on this forum.
There is a great but long thread on E38 idle tuning.

I found it super helpful in tuning my LS7.
Buy a 3-day subscription to GMSi for 20 bucks and you'll have access to complete service information, incl. wiring. GMSi is the same on-line service info. dealers use. Go to the ACD TDS web site for...
For the first time I read the cal in my '18 Colorado w V6.
What's with the "High Octane DP" spark table?
There are two reasons for the speed limiter and both are for safety
1) tires.
2) prop shaft critical speed.
It's pretty obvious what will happen if the tire's speed rating is exceed...
On a regular basis, If I am using the back arrow key to move the cursor backwards in a scan, I can go a ways and then the cursor stops and a Windows error box pops up.

Thanks for the reply, Bill.
I assume that any firmware updating has to be done with the MPVI2 conected via USB and not wireless. Also, if resynch automatically checks for firmware, how often...
I decided to finally move to the MVPI2 for an article series I'm writing for the Corvette Forum.
Since I had to turn my MPVI in to get its data transferred to the MPVI2 I have no way to compare...
I had a similar but not exactly the same problem. I made it better by...
1) disabling spark smoothing
2) setting the main spark table in the cells in which the engine idles to the corresponding...
I'm just a rookie tuner, but in reading all the comments, especially the one saying many of the calibration changes made sucked, I think one possibility I'd consider is that the tuner you had working...
I am going to bet 50/50 that the problem is not all calibration, but that you don't have enough airflow above 6000 for that cam work well. If that's correct, then you need at least an aftermarket air...
My LS7 is in a 2012. It's an H/C/I engine at a modest 600-hp. I was going to attach my cal file, but then I read that you have a way more camshaft than I and you're running bigger injectors.
