M135i and M235i Custom ECU Remapping (no tuning boxes!)

Why would you fitting a tuning box when a genuine ECU remap is available ?

M235i M135i Custom ECU Remap - NOT tuning box

The M135i and M235i are potent in standard form with 320bhp available but there are substantial increases in power and torque to be gained from a MoreBHP custom ECU remap.

With our own M135i with 8 speed sport auto we sent many months developing the first M135i remap available in the UK. All these carefully developed features can also be utilised in the M135i, M235i, 435i and 640i.

Disappointingly for the tuning world it has seemingly become common to fit a tuning box to this engine which fools the ECU in to producing more boost than it realises, without accurate corrections to timing and fuelling. Sure they do allow for more performance but in no way comparable to power/torque delivery of a carefully calibrated remap which allows the ECU to function as intended.

With just a Stage 1 remap calibrated on our rolling road we have seen 390bhp and 580Nm.

Apart from a better running car our remap also offers other benefits such as-

  • 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
  • Selectable power modes for ECO, Comfort, Sport and Sport Plus
  • Lengthened exhaust burble on lift off
  • Speed limit removal
  • Higher rev limit for manual cars

Our only real recommendation to further improve the M135i and M235i is the fitment of a Wagner FMIC - this offers real benefits keeping the intake temperature charge lower with improved flow.

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
