Had Mike Benvo flash and code my 2010 E90 M3. Don't post here often, but figured I'd share.
Dynoed my car on same dyno in 5th gear few hours apart:
My car is almost stock:
- AFE Intake
- AFE underdrive pulleys
- Eisenmann Street Exhaust
To me the biggest improvement was in throttle response at low RPM. It's a lot smoother and very easy to modulate. The initial tip-in on throttle is a lot less jerky, yet strong. I swear it feels like it has more torque down there. If it's a placebo effect at play, I SURE LIKE IT. Overall, it feels as if car pulls from the very bottom to the red line a lot smoother. It just begins to build and builds and builds and builds all the way to the top. Definitely feels a little stronger than before.
He also flashed Euro MDM and Euro M-DCT software. Can't comment on Euro MDM yet, but I will once I get to play with it a little more.
Euro M-DCT feels better. It's hard to explain exactly what is better. Full throttle upshifts definitely feel different in a good way. Smoother yet just as quick. The only thing I don't like about it, it now always defaults to D when going from R/N to D/S. So it's two bumps now for me as I don't go into MDM/S5 right away which is what my (M) button is programmed for.
He also coded a bunch of options for me, made my angel eyes brighter, few other convenience options.
Overall very happy with the whole process. Mike has shipped necessary cable/tools to my favorite installer here in Raleigh, NC and did the whole thing over the internet. Smooth, quick and very convenient.
My installer (Dan Connor @ Bimmer Performance Center http://bimmerperformancecenter.com/
) is a Certified BMW Master Technician and is also impressed with Mike. They are a reputable shop. I see a lot of race cars there often for engine work. He had a lot of questions for Mike before he put his seal of approval on this upgrade. Afterwards Dan said: This guy definitely knows his stuff.
Thank you Mike!
