Have you tried the Tow Haul mode with the DoD engaged? Our Suburban always seemed like it had a lack of torque in V4, but the TH mode made instant fuel economy numbers go up. Not sure what type of driving you do, but the TQ is what you really need for in town stop and go traffic.

Just glad to hear your doing well and have power. Do you have have to carry a weapon while pumping gas these days? I heard a guy in NY or NJ pulled a gun on someone when they tried to cut in line. Isn't America great!

No worries about the tune, your family and life come first.

I'll keep at it with Lew then.

Thanks

Mikel,

I have not seen any responses in the GM Trinity TCM support sticky regarding a question I posted about Diablo adding anymore transmission tuning options in the future. I have the Trinity installed in my 2010 Suburban and Lew is trying to help get the shifting to my liking.

Can individual ...

Mike,

Do you guys intend to add more TCM functions like part throttle shift points mph or rpm? Lew pretty much has the PCM tune dialed, just trying to get the shift points dialed in now. It seems like there are way more aptions in the Predator, at least for the 4 speeds.

Just wondering if you ...

Trade in your Predator for the Trinity and you will be able to disable AFM. You won't need a custom tune, but it is highly recommended. There are still things that onl;y the tuner can change.

I played with the RPM shifting in the ECM part and it helped a little. Definetly shifts better from first to.second.

OK. I read back through some posts from when the TCM support first came out and found a where you revised the shifting multiple times. Is what I am describing above seem to be normal?

Mike/ Johan, have you had a chance to look at this log?

I have another question about the WOT shifting particularly when downshifting from 6th to 4th/3rd. At highway speeds downshifting from 6th to 5th is fine and driving around town the part throttle downshift is also good between all gears. It's just at WOT it seems like it revs up, slips a little ...

OK. Do you think we will ever have some of those capabilities for the new trucks?

I have a U7193 in my 05' GMC Sierra Denali and it just seems like there were more options. Maybe not?

Anyway can you add a parameter in the Trinity for part throttle shifting points in MPH? I remember the U7193 having an option for shift timing as well.
