Default 6A shift programming

My C7 coupe shift program seems to have a fuel cutoff built in right at the instant of gear change. It causes a momentary loss of power for an instant, and creates a pop in the exhaust note (NPP equipped).
This happens with either full auto mode shifting, or in paddle shift mode in any and all driving modes. I am sure this was intentional to save on tranny wear and tear, but I liked the "hit" my C6 gave when it shifted out and the front end jumped up and chirped the tires.
It only happens at full throttle, and the shifts are very crisp and fast, but instead of a kick back into the seat, it does the opposite for just an instant before picking up to WOT.
My question, can this be programmed out, to shift like my "old" 2013 C6 with the same transmission?

Default yes

That type of tuning program is there to save wear and tear on the transmission and it can be changed.

All GM says about it is there is a 100ms fuel cut off which enables quicker shifts. As far as the "Hit" I have not experienced any different sensation than my 2008 A6. I assume it can be programmed out if you are willing to lose your 3/36 or 5/100.

Exactly, the fuel cut is there to substantially reduce shift times. I would guess programming it out would be counterproductive.
Upshifts in the C7 are very crisp, particularly in Performance Shift Mode, not sure why anybody would want to change that.

Last week I let my buddy drive my C7. He said" it feels just like a regular automatic." I told him my C6 felt that way when I first got it but after 8 years the tranny really popped thru the gears. So I told him to give it a little more throttle at the next light. "Wow!" was all he said....me too as I hung on!

I had Chuck Cow retune my trans and it shift awesome now. He also did a engine and I got his Cow Booster that really woke everything up. It's very responsive now and picked up a couple more mile to the gallon. Give him a call 914-332-0049. If you call him tell him that Charlie post this on the Forum. He can take care of you.

We're just about ready to announce our new MAIL ORDER TUNING package for C7.

Using our AutoCal remote tuning device I'll be able to offer complete tuning services for C7 Corvette

that include our CoW BOOSTER!, full DATA-LOGGING, and TUNING and it will even be possible to upgrade your package

to include serial wideband datalogging to take mail order tuning to a whole new level for C7.

The AUTOMATIC TRANSMISSION in the C7 is even better than the 2013 C6 and you'll love the new Chuck CoW

A6 TRANS/TUNE/& BOOSTER! package. If you've already tried other C7 REMOTE tuning solutions, you'll REALLY LOVE ours.

Watch the forum for details and release date.

Stay TUNED!

Likely not... We're too busy here and that show consumes much more time (for me) than the 3 days the show lasts.

Corvette production is the lowest it's been in 20 years and lastly, many of us vendors have lost 10's of thousands

to Tornados and similar weather that historically ruins at lease one of the three days every year and sends the

crowds home for shelter. Many other big vendors have pulled out too.

I'm expecting that if the weather is cooperative we'll do an event here at the end of the summer.

Watch the forum to see what we're up to over here.

Thank you.

On an acceleration run, with trans. in Drive, is there any way to get a 1st gear start from a dead stop? It appears that it starts in 2nd, no matter what.

Wish I could come to Florida. Your post seems to indicate that trans. starts in 2nd gear without some kind of reprogramming. Correct?

Why do you think it starts in 2nd gear? I don't believe this is correct.

and im looking for this answer too, it seems that in drive(at start) its in 1st gear, but it never drop's down to 1st again during the run(even when needed) its seems the car has to come to a dead stop before it will drop into 1st again. this is what i feel in the seat, i wish it would drop in 1st when it can, hard tight turns-ect.

Communicate with Charlie (Creekside in this thread).

He's a great guy and we spent tons of time getting all the bugs ironed out of the new C7 tune and pleanty

of time making the CoW BOOSTER! a KILLER just like it was in the C6 cars.

Something you can't live without once you try it.

We can do it via mail order or in person. We even have option for shipping/ Exchanging ecms.

but does your trans tune drop back into 1st gear from 2nd when needed while in DRIVE, track mode. to me this is the only thing im missing on my c7( yes i have thumbs) but in tight autocross events their are many times when i miss shift points by just a few yards. i will be calling myself but just wanted to know what you feel, to most this does not mean much, to me (everything). thanks

YES, it can be done either way.... Sometimes you're placing it in first and launching from there or other times, you're starting from 2.

Changes the feel completely for the better.


Give both a try and see what you like best.....

I would not recommend "tuning" your C7....it's an engineering marvel from the factory with a warranty !!!
