Gearhead Tune Questions.

Dzlnut · Feb 13, 2015

I just got my MCC Unlock and Gearhead Tunes ,what are the differences between the trans tunes?

Econ
Hyb
Regular

I loaded hyb tune to start with.

What setting is everyone running with the engine tune? I have not went any higher than the tow setting so far.

i run the biggest engine tune.

regular shifting has higher shift points than the rest and i like it. but i am running 35" with 3:55 gears

econ shifts and locks early which i hate because it is only good under 50% throttle.

Hybrid i have never ran.

Straight from Larz when I got my tunes. I asked what the difference was.

Anything above wot and all files should be the same. The Economy and Regular file will lock the converter in 3rd gear on up. The Economy tune should shift and lock the converter 200-300 rpms sooner than the regular file. The Hybrid file will only lock the converter in 5th and OD. It tries to keep the rpms above 1800, that file was really intended for the non vgt turbos and trucks with factory gearing and large tires.

Looks like I need to change my trans tuning, I'll try the economy tune.

Eco or Reg if you still have factory style compounds. Hyb is more for the single turbo crowd. Reg is for the guys with 3.55 and 33 inch + tires but some guys with the lower gears like it too. eco shifts sooner than reg, but all files are the same above 1/2 throttle.

I like the reg with 3.73's and stock 34.4" tires. Even on my light little reg cab.

Some people do... I try to tell everyone that the 6.4 has great efficiency cruising around at 1700-1900 rpms, but some people have to have it shift into the next gear.
