Q: I’m using MHD. What Map version should I flash?
A: The xHP OTS Maps have different TQ Limiters applied. Choose your file, depending on the TQ figures your
engine produces. You will find the TQ Limits in the Map descriptions. In the past, all ECU (Engine) Tunings were
tuned to send false TQ Values to the transmission, to circumvent the TQ Limiters inside the TCU. With xHP this is
no more necessary, depending on the OTS Map you choose and the max. TQ your engine is producing. For
example, the Stage 3 files supports a maximum TQ of 737 ft.lb. (1000 Nm). If you have chosen the right OTS file,
you are advised to flash the MT (Manual Transmission) flash from MHD. Only if you choose an OTS Map with TQ
Limiters below the max. TQ from your engine, you need to flash the AT version. In general, this is not
recommended.
