Over the last few weeks we have been working on our ECU Remap/Flash on our M2. The car is currently stock bar the ECU remap. We will be adding downpipe, exhaust, FMIC and Intake over the coming weeks/months. We will also be working on a back end flash for those running JB4.
As the N55 in the M2 is essentially the same as in the M235i we were expecting to get the same results. For reference a stock M235i makes anywhere between 333-345 BHP (flywheel) on our Dyno Dynamics machine.
The ECU tuning process requires removal of the ECU so that it can be flashed on the bench. During this process we can also unlock the ECU so it can be in the future flashed via OBDII using our Evolve-R cables.
These are our initial dyno graphs with the car using 99 RON (93 Octane) pre and post tuning. They are the highest stock figures vs the highest tuned figures tested back to back
Flywheel Power
Wheel Power
We will be providing verified Vbox tests as soon as we get a chance to do some runs. It does appear this platform will be limited on bolt ons and tune and hybrid turbo will be required for those wanting some serious gains.
The tune is certainly noticeable on the road with the car being more responsive and providing a nice linear power delivery which means the car is still very tractable/predictable.
