Review: Sutphin Custom Transmission Tune
Hey all,
I got a transmission tune from Rod Sutphin a few months ago, and it has been a great experience. The process was very simple (way easier than a DME tune) and it just overall makes the car more enjoyable to drive. Everyone's final product will be different since it's tailored to the individual. But this covers a few of the changes that I appreciate the most. |

quick question about this upgrade... i'm guessing that if you're doing a custom trans tune with sutphin, you only need to purchase the XHP flash license and not the map pack?

Decided to pull the trigger on this after watching your video @kern417. Worlds of difference. Rod got back to me within a couple of hours, amazing customer service . I also just got started tuning with Doug Newton and paired the transmission tune my 340i is new animal.

B) Yes he does send you a one and done file. There are no tweaks/revisions to be made unless you specifically ask for it after the adjustment period. I got the rev46 for racing |

I also got the xHP Tune by Rod Sutphin for my stock “mppk” N55 with the HP50. Very easy to work with and amazing support.
I went through the adjustment period yesterday night at around 3am did around 35km normal driving… then tested highway ramp WOTs .. and it’s completely a different car. Very happy with the tune and will most likely do a separate review after a few weeks. Thanks for the video recommendation Kern 👍

I have one of Sutphin OTS map as well for the 335i n54 at 6700rpm shift.
Question, would like to change the Shift rpm to 7000, can this be done using the XHP customization, has anyone done that?

Sure you can override and customize any of the settings, at least I have in the past with no issue. One thing Rod told me was if I wanted to retain all of his settings in the custom map, to leave all of the customizations OFF.

Guess that is what I was asking. I like his map and want to retain the settings (better than xhp) which seems to imply that even for a shift rpm change I will have to use his service.

This is literally the best money spend on the the 8AT. I didn't quite grasp what kern417 meant by it "anticipating what we wanted".
If automatics were shipping with this type of mapping, it would really kill off that stigma of being numb slush boxes. You start to brake, it's pre-emptively downshifting for you. Really nice! Need to "abuse it" more now that the adaptations are done, but manual shifts were fast, crisp and smooth. |
