Custom transmission tuning for the BMW models 335d, X5D, 135i, 335i, 335xi, 535i and 535xi and many European models using the ZF6HP19,21,26,28 transmissions. Vehicles with a build date of 03/2007 or older will have older software and I can not tune that version.
Only on the 135i, 335i, 335xi,535i,535xi the DME tune has a few tables that must be adjusted to run correctly with my trans tuning or if you are running MHD OTS version 9 maps you are all set.
The XHP Flashtools program is required with the general license to flash my custom transmission tunes. If you are looking for a great overall all in one driving or racing performance transmission tune with fast, smooth shifting, better throttle response and feel of power you have come to the right place.
DRIVE MODE: is very smooth, quick shifting, better shift points, improved throttle response, and power. Perfect for daily driving and comfort, without sacrificing performance and power.
SPORT/MANUAL MODES: are much more aggressive, faster, firmer shifts, higher shift points, throttle response and power. Perfect for racing or very spirited driving.
Custom changes made per Gear and Mode:
- Shift timing
- Shift pressures
- Fill rates
- TQ Limiters
- Shift points
- TCC settings
- Mapping behaviors

I purchased this tune to replace my XHP Stage 3 tune. This one shifts much nicer. Sutphin does a ton of work to make sure the tune is the best and specific for each level of tuning and modification. I also highly recommend the Sutphin reman valve body solution over zip kits or DIY rebuilds of the valve body.
You will not look back after Rods TCU tune! A must have
Rod Sutphin has been one of the best people I have ever had the pleasure of dealing with concerning tuning or performance upgrades on my car. I was not completely satisfied with the Stage 3 xHP tune, so I decided to give Sutphin a try. I have not had the TCU tune installed long. It seems to be smoother shifting so far but I need to put more miles on it for sure. The level of service provided by Rod is worth 5 stars alone. I emailed him a question, within a couple hours he responded. His message was encouraging so I bought the tune. I sent him my backup file around 7:30PM and he had the tune back to me within 30 minutes. I was honestly amazed at his level of customer service and for that reason I will recommend Sutphin!
Fantastic improvement. Smoother shifting, sport mode comes alive with quicker upshifts and having gear indicated in instrument display/dash is sweet.
