I like the power delivery of the CS tune but prefer the optional brute punch of stage 1, but with a progressive rightfoot you can get CS output with a stage 1 tune but still have the punch when you want.

I'm not concerned whether its like "OEM" just whether I like it.

Every tune is different when it comes to power delivery. Stage 1 just takes a little more work with a stick. I think stickier tires and coilovers would make a difference. Stage 1 93 octane on a stock car is spin city.

In fact I'd say that this tune shifts better that any tune I've tried including the stock M2C.
I think for a beautiful balanced driving experience the M2CS is the top tune especially on the twisties and around town. If you want to blow away all other M2s on the dragstrip or the freeway at high speeds then go for a stage 1.

Does it mitigate the boost delay on quick shifts?

Yes, it is super smooth and power is there after a perfect shift.
Don't expect any turbo surge with this one.

Wow that's really good news! Can't wait to get it programmed now

The only thing I changed from the original download was GTS roar and exhaust flaps open in Sport/SportPlus mode. This tune continues to reserve the SportPlus mode for extra cooling.

Whelp adding this to the "to do" list. There's a local BM3 vendor that can do the DME unlock for me.

Anyone else have some input on the M2 CS Map versus the Stage 1?

[m20e3087]

Anyone having issues with new Mac OS? I having connection issues.

Can they do it without removing the DME or is removing the DME the only way?

I believe it has to be removed.

You do not need to remove the DME it can remain in place for a bench unlock (pre july 2020).

For me flipping the TMIC works (5min work), there are guys who access from the bottom of the car using a mirror and pre installed plugs to connect to the DME in stead of wiring to the individual pins (which I do). Personally I consider fliiping the TMIC such an easy route I would not consider putting the car on the bridge and remove the skidplate etc.

If you have done it before and have the right tools (like Autotuner or Bflash) it's ca. an hours work incl your preparations.

M2Cs built before March 2019 (or so) can be unlocked and flashed through the OBDII port. There is no need to remove the DME. Cars from April 2019 to June 2020 need to be bench flashed or manually wired to the DME for unlocking. Unfortunately after July 2020 there is a good chance that because of the new Bosh encryption the DME will be unflashable except by BMW.

My M2C was built 2/2020 so ya I have to remove but what you're saying is that there is another option. That's pretty cool.

I wish there wasn't a need to bench unlock but I guess it is what it is.

Yep for my car it has to be bench flashed.

That's good news, I'll make sure this guy is aware of that. Thank you!

Find a local tuner that supports the platform you want to use. If they can unlock it (have experience) and then install whatever tuning pkg you like.

There is no need to pull the DME out, but they do need to move the A/W intercooler as others have mentioned to get at it.

I had mine done in a couple hours while I waited. Had to drive 200 miles to find a shop that could do it here in the NE. I wanted to get ECUTEK installed but it just wouldn't take for some reason. Ended up with BM3 and now am finalizing a 93 Pump custom tune with Cary Jordan.

Car is wicked now

Thanks for this. Ya I'm sure I'll find someone that can get it done. I have Bootmod3 and am just going to run the CS tune. It's got plenty of power for me as is and when I add DPs w/full exhaust I just want to turn off a bunch of things like cold start, roar CEL and other basic stuff.

Ok I've just gone from the CS to Stage 1 map

Here are my thoughts:

- Stage 1 map is much stronger and more responsive than CS, especially out of boost in low rpm and part-throttle
- It feels more like a naturally aspirated V8

- I've got the boost by gear reduction at 30%, 20%, 10% in 1st, 2nd, and 3rd gears respectively.

After changing between the two, I much prefer the Stage 1 map, especially with 15% ethanol in our garbage gas up here in Canada.

[n8dgr84]

Is it possible to "tune out" the rev-hang between shifts on a manual transmission?
