8 Speed Transmission

[jay p]

I installed it on my 2015 Silverado. The shifts are firmer. I haven't had time to play with the shift points yet.

So if it's a 2015 you must have the 6.2 with the 8 speed.

Yes

Boy people pretty quiet on this new 8 speed tune. Not sure how how to take this ,,,?

[mikel]

Its out there....

[toneyjay]

It looks as though I never received that file for processing. I still haven't received the file you tried to email me today as well....

For what it's worth, your vehicle is not currently up to date on calibrations. If it were, you'd already be supported on the latest tune database. GM has a ton of calibration fixes out for the 8 speeds. You can see the list for your vehicle attached.

I will be adding support for the calibration you posted, it will likely be next week before another tune revision goes out though.

Any update on my version? Thanks

I updated my I2 and loaded the 91 tune with 8speed tcm hard tune on my 2016 Denali 6.2l and everything went fine, however I have lost the ability to make adjustments to the tune besides tire size and speed limiter. Turning off the AFM is on the top of my list.

Other than that, the tcm adjustments seem pretty good

Here is my info.xml

Something I failed to mention in my first post was that I restored the factory tune before flashing the new tune including TCM

Thanks for taking a look

Everything looks fine there.

You're saying the only user adjustable settings when you go in through the ecm tune are Speed Limiter and Tire size?

Can you take a picture?

I will try again this morning, but it seems whether I choose easy or advanced it does the easy tune where I am prompted for tire size and speed limiter automatically.

Go through the advanced menu and select your tune. Then select modify tune and you should have all available options there.

Hope I am missing something, but no matter what I try the modify parameters is always grayed out in advanced

[Zach]

Ok, select standard tune, then pick the tune you'd like before it loads the tune, it's going to ask you if you'd like to modify parameters, that's where you select what you want.
