Tuning/68rfe questions

[JtRenegade]

I was looking at the tune on my personal truck(2010) and noticed in the pedal to torque table there is an entire column for negative throttle position. Is this necessary? How could I ever have negative throttle position?

Does anyone know if the 10-12 trans tuning is similar enough I could borrow some trans tuning from a tune for a newer(13+) truck?

Thanks

There’s a reason for everything on why the tables are set the way they are. As far as using visible transmission parameters from a 2013 and putting them into a 2010-2012 calibration, there is almost virtually no difference so what’s the point? Stock trans tuning no matter the year just isn’t that great in general so why waste time with more stock trans tuning when you can just adjust it and tailor it to your preferences for a better driving experience.

I should have mentioned that I was not talking about stock trans tuning. I've got a few tunes that shift really nice but they are for 13+ trucks. I manually copied everything over to a tune I am working on for my 2010. I have not tried it out yet but I'm guessing it will be fine.

Thanks for the response

Yeah it’ll be just fine. There is a difference in axle ratio between the 2010-2012 and the 2013-2018 but not enough to make any real large impact. The code is a bit different between the 2010-2012 and the 2013-2018, well each year and each revision it’s slightly different but almost all shared parameters between them all are damn near virtually identical. Just new stuff really is added as far as coding and parameters go as you get into the newer stuff.

Awesome thank you, that's the input I was hoping for.

Hey JT, Would you be willing to share that 13+ trans file? Trying to build a file for my personal 16 and would like to compare a few things. Thanks!

Just use your 2016 tune file, there is no difference between the the 2013-2018 model years, they can all be found on the forum too

I was interested in comparing his 13+ tuned trans file, not the stock version. Unless I somehow misread that JT was sitting on that.

I want to do my own trans calibration (no commercial interest, just personal) and it would help to have something to compare it to.

I have a couple of them, I'd be glad to share.

Adjust shift and lockup tables up and down till it feels like what you want, nothing more to it. Everyone has their own preferences and desires of how it shifts and lockups, really all boils down to personal preferences
