Well, I tune my '12 JGC 5.7 with 93 oct tune.

I used an i3 tuner (84.45-1). I want to disable MDS and change throttle response.

In advanced menu I can only change tire size and traction control...

Any idea??

Other problem, since I calibrate tuner on car, cooling fan run at high speed when engine runs....

are you selecting quick adjust?
you need to go to the 'modify parameters' menu.

I tried Easy tune and the other one.
I don't know why but sometime it works, correct l'y (I got all items) and sometime I only have tire size and traction control...

Do you have an explanation for the cooling fan that has been running at full speed since I connected the Diablo to my Jeep?

fans are set to run more often to keep the engine cooler.

Okay, so it's normal for the cooling fan to turn on as soon as the engine starts ... even if the engine is cold?
I can hardly believe your answer is meant to be.
That the fan turns more often on an engine whose operation is optimized and which is more requested, no problem.
But the fan is constantly spinning at full speed for no reason, I doubt it.
When I restore the backup, the fan also starts up, but not from the start, a few tens of seconds later.
My fan will drop before my tank is empty ...

Here are the two tunes and the info file.
The problem appeared when calibrating the tuner on the car.
I haven't changed the fan settings
