    MINI MAXX HELP

    Hey guys,

    I understand that this has been a common topic among most Cummins forums which I have read over and over again. I am new to diesels and I and getting ready to do my deletes (egr, DPF, throttle valve).

    With that being said I just picked up a mini maxx tuner and got the trans overdrive which I have read is almost a necessity with the 68RFE. Everywhere I look I see opinions on how to set up the tunes for the truck and half of it is Chinese to me.

    I'm sorry to have to do this again to the Cummins world for the millionth time but I cant afford my truck blowing up because of my naivety.

    So I have a 2012 6.7L 3500 with the 68RFE, I am currently not towing with it and I'm not looking for crazy performance just better mpg and longevity of the truck.

    I always see talks about timing, att, defueling, and what not that I have no clue about.

    Any help would be greatly appreciated and again sorry for bringing up this again.

    Thanks all!!!

    Hey bud, I just traded my 2012 2500 6.7 with the 68RFE. I also had a MINI MAXX on it. (Came with the truck). I purchased the trans unlock code right away. It had the “box tune” it came with, I purchased a couple custom tune files from a vendor here. I also downloaded the “hot damn 175” tune from the H&S site before they closed down. I had a few inquiries from members here asking me to send a copy of the “hot damn” to them. Unfortunately I did not... with little to no support left for the mini max platform I didn’t wanna “mess “ with what was working for me.

    I downloaded the complete owners manual for the mini max years ago (you may be able to find it online with a google search). As for actual settings on the unit itself. This is what I had my defuel levels set at....

    Cold coolant temp 180f

    Hot coolant temp 220f

    Trans temp 190f

    Max boost 35psi

    Not sure what other defuel levels were on it? LOL. traded the truck two weeks ago. If you need any other info just PM me.

    Maybe other guys will chime in too and give you their opinions.

    My truck never gave me any issues running with the mini max at those settings. Towing or empty , etc etc.

    The H&S box tunes tend to run high EGT's.

    I wouldn't run more than the 120 tune for daily driving.

    Even then, just short wide open runs. Leave timing and other settings on default. Using the cold coolant defuel is fine, but just use the warning chime for other temps.

    You don't want it defueling when running hard with advanced timing... Good way to lift the head. EGT gauge recommended.

    Re: MINI MAXX HELP

    I ran a mini for almost 8 years on my ‘11.

    I ran no att, timing on 2 and set for tow.

    Also have the trans tuning. (A must)

    Do not run any defuels. They can cause issues when active

    I still probably have all the tunes and the stock sd card contents if you need them.

    Great.

    Make sure your batteries are fully charged and engine warmed up before programming the ECM.
