For those of you who have used the MM3 and/or other tuners can you help with a few basic questions from a new user?
I installed my DRD tuned MM3 a few days ago... questions.
1) Can I select a tune "on the fly" or do I need to be sitting still idling after start up waiting for it to load?
2) I have not set the tuner up to start with a specific tune at start up. Does this mean its running stock if I don't select a tune?
3) Do most of you set it up so it always runs a tune like a 60HP tune at start up? If you do have it set up for a 30, 60, etc. on start up, what if you want to change to a 90 or 120 just for one drive?
4) What do you all use for towing? Do you turn on the tow/haul mode on the truck? Do you turn off the overdrive, limit shifting to 5 gears etc. while running the tune?
5) What are you all showing on your display? What gauges have you chose? I have an EGT sensor to install but as for the rest I'm trying to decide what is best and would like to know what others are doing.
6) I will be adding a lift and 37s hopefully next week. I haven't looked for it yet but was told there is a way to adjust tire size so MPH reads correctly. Probably a silly question but I assume when I adjust the tire size in the MM3 it will correctly adjust the speedometer on the MM3 display but the speedometer on the truck will be off right? The MM3 doesn't control any of the truck displays right?
Thanks a lot for the help.
