Stage 2+ E30 octane OTS maps for N55 EWG and M2, upgraded HPFP required. PWG172X map updates will follow.

We decided to make a new OTS map for the N55 equipped cars with an upgraded high pressure fuel pump.

The limiting point on cars with the N55-EWG and N55-M2 engine is that they run out of fuel pressure before the turbo runs out of steam.

These maps can be used with upgraded turbo as well, an example is the car we had on dyno.

The dynograph shows the Stage 2H E30 octane OTS map compared to the new Stage 2+ E30 octane OTS map on a car with a Pure Stage 2 turbo.

Stage 2H E30 octane: 447WHP/452WTQ
Stage 2+ E30 octane: 501WHP/512WTQ

Stage 2H is our previous OTS map that maxes the stock HPFP. Stage 2+ is the new OTS map that takes advantage of an upgraded HPFP, in this case from Dorch Engineering.
These cars produce around 290-305WHP stock, with this map and the same upgrades like the testcar, a 200WHP gain is possible - at 20 PSI! ��

Required hardware:
- Aftermarket chargepipe
- Aftermarket intercooler
- High flow downpipe
- Upgraded high pressure fuel pump
- Pure Stage 2 (numbers in pics posted) or equivalent turbo upgrade
* AFTERMARKET HPFP MUST BE SET IN THE CONFIG *
- Upgraded high pressure fuel pump Map Configuration for the HPFP should be set before flashing

We recommend XHP transmission flash to take advantage of the high torque #bootmod3 #bm3 #bmw #bmw235i #135i #235i #335i #435i #535i
