Hello All,
I have a 08 Ford F-150 5.4 with the 3.55 gears. When I try to adjust to that gear ratio it goes from 3.25 and jumps to 3.75, with no 3.55 option. Should I pick the axel ratio that's closest or is there a way to set is specifically to 3.55. I have the original Intune system, not the i2.
Thank you,
Austin

if it will not let you select the new gear you installed, please post the tune files from the intune drive here and I will fix it for you.

Hey Mike,
thanks for the reply. Im new to the diablo so how do i post the correct file off of the intone? Im just using the 87 octane tune with a couple minor parameter tweaks. I haven't changed any gears in my truck, i just simply have the 3.55 gearing, which is pretty common for f150's. Also, is there any way to adjust the tcm on these devices?
thank you for your time and patience,
Austin

i believe this is the correct file?

if they are stock gears you do not adjust anything for that, you only change the axle ration setting in the tuner if you have changed gears.

Okay thanks, so basically it's already set on 3.55 before adjusting anything?
Does this device have any tcm options or only pcm?
Thanks,
Austin

there is trans control, its not a seperate TCM on these Fords.

Thanks
