JB4 for M2?
This might be a dumb question, but curious if anyone knows.
I have a M235i currently with JB4. Obviously this car has a N55 engine. Will the JB4 work with the new M2 N55 or is it more complicated than that?

I would doubt it even though they both have the N55. Timing and boost levels will be different stock and therefore a tune will need to account for that.

Could possibly get a new tune and upgrade the firmware on my existing JB4, or would you think a new unit and new harnesses?

The M2 M3/4 use a different ecu than the regular N55 so you will need a new unit.

Lets be serious here. The M tax is real, I would be very surprised if burger tuning don't take advantage of that (which you can't blame them for, at the end of the day they are a business and will do what any smart business would to make money) and require a new JB4 unit/harness to mate with the M2.

500whp is easy to make on the M3/M4 with the JB4, that being the case, it isn't much of a stretch to assume the M2 can make 450whp or so with a JB4.
Happy modding!

The M3/4, and its twins, could easily have MUCH more headroom than the single turbo M2. Maybe I'm drunk, but how do all you people making completely baseless assumptions afford the car? Who pays simpletons so much?

I will bet you $100 via PayPal that the M2 JB4 tune will hit 450whp with an E30 blend on map 2 or map 7 with downpipes. This is not much of a stretch at all to assume these figures considering the overhead BMW leaves with their current tunes and the JB4's ability to max that out. A delta gain of 80whp is VERY VERY VERY much so possible.

Lol, look, BMW's of late have traditionally dyno'd very close to their quoted BHP level. With the S55 in the M3/M4 this was the case, considering the same marketing/performance-assessment "engine" decides on a BHP level for the M2, one can infer that the same sort of process will be in place for this next round with the M2.
If the M2 stock puts down roughly 360-370whp, stretching that to 450whp with the tune (and fueling) overhead BMW leaves us is very possible...especially when you add E30 into the mix and are running an aggressive map like Map2 or Map7. That is why I posted that a delta gain of 80whp should be entirely within the realm of reality for the M2.
