What did you end up deciding to do? I have a manual trans, so don't know the definitive answer, but in my mind... if you disabled DoD on the engine side, the trans should never even need to utilize...

Could you post a log of it happening? Might be easier than just shooting in the dark with suggestions.
Were you given a base map to start with after installing the Magnuson?

For some reason I think the ([6310]=9 OR [6310]=14 OR [6310]=15)=0 is messing up the filter for me. I'm in a 2017 C7 Gen V.
I wonder if the my Fuel Trim Cells are messing me up since my Airflow...

Hey fellas, thanks for the updates and the additional explanation.
I did get a chance to mess with Cringer's tool this weekend and it's addictive! Kind of fun to be honest. It's satisfying working...

I've been looking into Cringer's tool and it really seems awesome. Excited to start using it! Good to know about the fuel display corrections.
I was discouraged adjusting the VVE tables the first...

Hey all, just had a random thought.
Whenever I've tried to adjust the VVE table in the past, I've always had the Intake Cam "Desired Angle" and the "WOT Desired Angle" maintain their advance (I...

Any more insight as to why these should be zero'd out?
Is this still the recommended method in 2022 for Gen V?
I looked through some other tune files and haven't seen anyone zero them out...

He straight up ghosted us!

What ever happened after you changed the VCP spark table? Or did you not zero that 0.16 row out?

Just realized that my PE/COT Spark table is set to pull timing from 0.70 - 0.85 airmass ... wonder if THAT could be a contributor now. Will try zero'ing that out.

Just did the 4th gear pull.
I eased into the throttle but started getting KR beginning around 2600RPM @ 0.60g. This is with stock HO spark table and other spark adders zero's (except VCP Spark)...

Yes this is definitely something my mind keeps coming back to and it annoys me quite a bit.
I'm not looking forward to removing the driver side header to fix the steering shaft fitment issue....

I was finally able to flash back to the stock VVE table. Still getting some KR but it seems to be less than before.

Car did feel slower. Thought it might be in my head but Virtual Dyno seems to...

When I first tried tuning SD with the MAF disabled, I had an area where the numbers were slightly off. The result was, when decelerating, the requested torque would be negative... then around 2k RPM...

Appreciate it!

I was thinking that the variable cams might explain it. Thanks for the further explanation.
And...not that I plan on doing this but I guess, if someone wanted to "simplify things"...

Ok, thanks. I guess I should change the dynamic airflow High RPM Disable back to the stock 4k RPM while I am at it? I lowered it to 2.5k RPM to see if that would help at all.

The reason the VVE...

And here is the spark table with actual values, not just the comparison vs stock

Could 12.5 be too rich for low rpm high load? Should I run it a little leaner then richen it to 12.5 at peak tq?
...

Just speed engineering headers and attack blue air filter.

It holds target PE afr pretty well. I've been playing between .85 and .87 lambda.
I just finished more pulls and the KR is so random....

Hey all, I am tuning my 2017 C7 with an LT1 and have pretty much completed my MAF and VVE tuning.
I had -5 degrees of timing pulled from the HO and LO spark tables to be safe during that process but...

Trying to understand cases when LTFTs being enabled could be dangerous. Could it potentially do more harm than good if the VVE is not adjusted? Or if the MAF is not calibrated correctly after...

Ok thanks fellas. Yea I figured it wouldn't be likely since I know the HMI fails on these things by themselves.
Of course it happened right after the warranty ended *sigh* and right after headers...

Hey all, I have a 2017 C7 stingray. 32k miles on the dash. Finally got around to installing headers and have been making lots of revisions and writes to the ECU.
I noticed that after each write, the...

How convenient. I have a 2017 LT1 Corvette. Here ya go.

I'm confused. If you are making boost, why did your tune file only go to 0.840 MAP/Baro on the VVE table when I opened it? Shouldn't the axis be set to 2 bar or is that just how it opened on my VCM...

This has been covered pretty extensively on the forum and on some YouTube channels like Goat Rope Garage. Check out his Gen V playlist.
Depending on the mods, you may not need to mess with the MAF...
