New BMW M3 M4 Custom ECU Remap

Tried and tested M3 and M4 remaps now available at MoreBHP!

M3 M4 Custom ECU Remap - NOT tuning box

The New M3 and M4 are true works of BMW art. Leaving little room for hardware modification.

However with the high hardware spec room can be found for improvements in the ECU programming.

With a slight increase in turbo boost along with carefully optimised timing, fuelling rework and various limiter massages over 500bhp is available. This is custom software enhancement only, no hardware modifications required - standard air filters, standard exhaust, etc, etc.

More importantly this is a genuine custom remap NOT a tuning box. Fitting a tuning box to such a car is total stupidity, we have tested these so called solutions and found the ECU having to close the throttle to prevent engine damage due to excessive knocking (the result of way too much boost without correct fuelling/timing calibration).

We have spent countless hours developing and testing MoreBHP software on our own M3.

New M3 M4 Custom ECU Remap

In addition to the obvious benefits of 500+bhp/700+Nm the following is also included-

  • Cold start off (especially handy if you have a noisy decat at cold)
  • Decat MIL off 
  • Exhaust flaps permanently open in Sport Mode
  • Enhanced Sports Displays to reflect the increase in power and torque
  • Optional selectable power modes for ECO, Comfort, Sport and Sport Plus
  • Speed limit removal
  • Higher rev limit for manual cars

Took my 328i in for stage one remap and very impressed with results. Bhp now up to 285 and torque increased from 350 to 450Nm.

Took my Mk6 Golf R for a Stage 1 remap after a recommendation from a friend. The guys put me right on the correct super-unleaded to use - yes they aren't all the same - and remapped it for me and I'm over the moon with it. Sharper pick up and great response especially in Sports mode so I'm one happy bunny and would happily recommend them to anyone. Cheers guys
