M135i and M235i (EWG) Custom ECU Remapping 

With just an uprated intercooler, from Wagner Tuning UK, 400+ bhp is easily achievable with a remap.

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, with an uprated intercooler the power figures climb to 400+bhp.

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
  • Remap cloak to prevent detection by BMW

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. With the intercooler we have seen 400-410bhp easily achievable. Fitting a decat downpipe would seem to release a little more low down torque and give a better feel. We recommend keeping the stock airbox and most intakes we have tested are of very poor design and make it difficult for the car to fuel correctlty.

Remaps can be tailored to suit fuel grade used, for example regular or super unleaded petrol. For the best power results we recommend that petrol cars be run on super unleaded.

Where the vehicle allows we can also add features such as speed limit removal, increased rev limit, launch limiter, hardcut limiter, exhaust flaps open, sports display dials adjustment, cold start off, Decat MIL off, DPF off, EGR disable, DTC (Diagnostic Trouble Code) removal and remap on the sport button.
