Will xHP work with my specific engine tune?
Yes, xHP will work with any engine tune. The most common tuning applications are:
MHD - Has a checkbox that needs to be ticked to ensure optimum performance, see the next question below.
BM3 - Works out of the box with xHP and with Stage 2 and higher, BM3 also recommend using xHP Flashtool along with their engine tunes.
MGFlasher - Also works out of the box.
See our line-pressure article for more in-depth details, regarding communication between ECU and TCU.
Which map version should I flash?
For most cars MHD offers a special "xHP Transmission Setting". In all other cases just select "Manual Transmission" in MHD. (yes, this is not a typo)
I already have a flash tune (MHD, BM3, MG flasher, custom tune etc) on my ECU (engine). Do I have to uninstall it before using xHP?
No. xHP has no direct effect on your existing engine tune and the order in which the engine and transmission tunes are flashed does not matter.
I've got a JB4, can I use xHP on it?
Yes, xHP will work on JB4 equipped cars, but you will need to remove and reinstall it before flashing. On our test cars, setting JB4 to map 0 was not enough, as JB4 still interfered with communication with the TCU. This may depend on the JB4 revision you are using.
