We are very proud to announce the worlds first complete remap of the 8HP50 transmission used in the x40i BMW's with the latest BMW B58 engine!
The 8HP50 is much stronger and more refined, compared to it's predecessor, while at the same time the stock mapping was dialed back a bit compared to the old x35i cars. Here at xHP we remapped the 8HP50 to show all it's glory. Through the DEC Switch (Comfort, Sport, Sport+) you can choose between 3 different shift speeds. Soft and refined or rocket fast and hard...the 8HP50 does it all.
We reworked all shift programs, overhauled the shift maps, removed a lot of nannys and had our focus to make Stage 3 a perfect match for tuned cars!
Experience the extremely quick and fast throttle blips in M mode or enjoy them in S/Sport+ in full auto-mode. Our logic re-design lets you freely choose how you want your transmission to operate and with the soon-to-come Custom Functions you will be able to setup your Launch Control, your shiftpoints, the intensity of your blips and much more!
Combined with a proper Engine Flash-Tune like MG-Flasher or MHD we guarantee you a completely transformed, even better vehicle!
xHP Stage 3 Specs:
- Added Gear Display in D-Mode
- Removed Torque Limiters
- Raised Line-Pressure mapping for high-input torque
- Less Torque Reduction during Sport+ shifting. Less boost loss under WOT
- Reconfigured DEC Logic, with similar logic as in M-Cars (access to more shifting-modes)
- Faster&harder shifting in M/Sport+, absolutely instant paddle response
- Very Strong blips on downshifts in M/Sport+ and S/Sport+
- Improved, more spontaneous Double-Downshifts (for example from 6th to 3rd gear or even 8th to 2nd gear)
- Automatic Shift-Mode upscaling under WOT (Trans chooses fastest shift mode on full throttle)
- Recalibrated Shift-Points in D Mode to improve throttle response
- No automatic upshifting in M/Sport+ setting
- DTC and DSC OFF activate the fastest shifting mode
- Launch Control improved
- Retains full ECO - Mode functionality including Coasting
