Hey guys, considering leasing an M2. Curious if there's an ECU flash to easily increase power? The engine in the M2 seems to be nearly identical to the M3, minus the difference in HP and torque, so I'm guessing BMW just detuned it? Is there a way to gain that power back?

I found this one, but the dyno chart seems to radically change the torque curve. One of the main reasons I want the M2 is because you get full torque down at 1,400 rpm, which is perfect for those powerslides from stop. I wouldn't want to get an ECU flash if it meant the torque came in later.

Any good ECU flashes out there that don't make the torque come later in the powerband?

FYI, the M3 and M2 engines are not the same. The M3 has the S55 and the M2 has the N55.

No. They're two completely different engines. The M3/M4 has two turbos and a MUCH more tunable engine. We only have one. Even with supporting mods like a downpipe, intercooler, intake etc, with stock a fueling system and a stock turbo you won't be breaking 420whp on an M2.

That being said, if you got a downpipe and a tune you would definitely notice some power gains. But no where near the same as what you would get with an M3/M4.

Thanks guys. Appreciate the clarity.
I'm mostly just interested in more low-end torque, so if a tune helps me get more of that, then great. Otherwise, wouldn't want to compromise the torque coming early in the powerband.

You want low end TQ, a high-flow catted DP paired with the Dinan boost control sport tuner is a simple, cost effective yet potent combo. You'll be easily at 400+ WTQ in the low rpm range. Throttle modulation is a must in all but perfect driving conditions on stock rubber.

Thanks! Do you have a link to a high-flow catted downpipe for the M2? Also, do you have a link to the Dinan boost control sport tuner?

Curious why you chose stage 1 over stage 2

Check this out its huge! No more DME removal required to get it

MHD is also the one latest to the F series game so HAVE A LONG WAY To go !
It's not who's been in the game the longest but who has been providing the World Records in S55, N55, N63TU, S63TU, N20 oh thats right PTF

Started with Stage 1 and then went over to Stage 2 afterwards.
.. also wanted to see what numbers I get with those mods for stage one

What were the stage 2 numbers?

This ^. More torque down low in this car on stock rubber is not going to get you much more than wheel-spin in the dry, let alone the wet.

And that's on 91 oct? Wow, good stuff.

Yes sir, 91 Octane...
...And no requirements to change/re-gap your plugs.

While those peak numbers are pretty consistent across most of the
BMW M2's we've dyno tested, the focus should be on the delta gains,
not on the peak power.



We'd happily trade a dyno plot showing 400 HP, for a dyno plot
demonstrating better area under the curve, and a delta that is
exactlyin line with our advertised gains.

*For this application it's averaging 50+ HP and 80+ TQ @ the wheels
with a very robust AuC!

On VF,
Yet to find a solid comparo posted here. By that I mean a true independent before and after. I had one better than nothing but dyno were conducted by VF dealer and on different days and different fuels (before=95RON, after=100RON=98RON + OCT booster), see this:
http://f87.bimmerpost.com/forums/sho....php?t=1402833

On BM3,
1) Info all over the place but this one (stock turbo) is most educative if I have to pick, though runs are from different days.
http://f87.bimmerpost.com/forums/sho....php?t=1455188

2) Below is by far the best dyno comparison but it's on upgraded turbo if you don't mind.

For M2 flashes from other vendors, I don't see any meaningful results available here.

Yea but it is still early.......the game is speeding up
