I have BM3 and MHD, I like them both but I can tell you that if you're going to stick with just OTS maps, MHD all day. You get all of their Stage 0 > Stage 2+ maps included with their license including multimap support. They both have rolling anti-lag and while I like MHD's choice of button to activate much better, BM3s really gives you a rocket feel whereas MHD doesn't (with OTS settings, a tuner can push it to BM3 levels).
Now if you are going to get a tuner, both are equally awesome but BM3 seems to be more popular in the US, especially with full E85 tunes. If you are looking for another level of OTS tuning, MHD does have both their very own ECA unit which provides a free Flex fuel OTS tune (yes you read that right) and they also have native support for the Motiv Re|Flex. I asked BM3 if they have Motiv support they said ask Motiv. I kind of left it at that but I can't imagine it not being compatible but it's nice to have that native app support. I'm currently running MHD with a custom Flex tune by Wedge Performance and it's putting down some big numbers with a safe AF:R and stock like idling quality. GL!

I have bm3 and honestly I think they are both honing to be similar in a way you can't tell unless you were to drive a car with each tune separately. I will say I've run many tunes in previous cars and the bm3 is by far the best. Absolutely no hiccups, issues, crazy power, user friendly. I wouldn't focus on which tune produces the highest numbers as every car is different and there's no way anyone can tell you for sure an ots map on one platform will make more power than the other. Also it's about how the power is delivered. I've dynod mine and data logged it. Very smooth power delivery but also it's so much I had to reduce torque in 1 and 2 gears (dct) bevsuse the tires spin at partial throttle. My car still breaks loose the tires at 45-50 mph when downshifting and flooring it! I'd look to see if you have any custom tuners near you and what platform they prefer and choose based off that…
Either way you will be blown away!

I know you didn't ask about this so I might get some slack about it, but I went from BM3 to Carbahn stage 1 and it's a night and day difference. Carbahn is a bit more money, but it's from Steven Dinan and he's doing crazy crap on these S55 engines. I feel a bit more secure knowing it's through a dealership and Steve Dinan. The only issue is you have to find a dealership you trust. I found a great one here in Durham, NC and they are cranking out Carbhan stage 2 and 3 cars, not just M3s. Check out Carbahn...it's pretty sick.
Caveat is that if you want super aggressive burbles and stuff, you won't get that with Carbahn but power you feel is completely different. Just my 2 cents. |

I agree, but I fried my ECU so for me it was a set and forget and I'm a little shy of doing it again. I do agree that BM3 is easier to use and has more options but the Carbahn is vetted by one of the best in the industry (according to my unqualified opinion) and it's more bite than bark so I like it. Everyone has their own preference but I love the Carbahn tune and won't go back to the others any time soon.

Actually, a lot of ppl have compared and end up with bm3 Seen a few of my close friends try mhd or ecutek because of the map switching crap but the tuners response time along with other annoyances came right back to BM3

I had bm3 st2 on my car and i switched to MHD. The biggest difference i can tell is that mhd is way more easier to use, with bm3 all the torque hits at lower rpms and on mhd the torque hits higher in the rpms. With bm3 i was losing traction in any 1-2-3 gear at around 4-5rpms, with mhd i lose traction up in the rpms and i can easily hook with 2 and 3rd. I tried to sell the bm3 licence but I'm having difficulty of doing it( their customer service is not great as everyone says, they will reply immediately but they will not fix the problem). And another thing that i forgot, on bm3 i had lot of timing corrections and knocking, on mhd i have way less corrections and zero knocking. Would i go back to bm3? I don't think so.
