What’s your current track toy?

[BMWcurious]

It was R35 GT-R until sold, so nothing track suitable presently except older BMWs for drifting, but I was quite a slow learner at that and not been recently.

BMWcurious isn't a tuner strictly. He's much more than that.

I'd take everything he says from an engineer's perspective. He's spot on. 20 minutes on an OTS map ( regardless of tuner ) relying on knock sensor to correct ignition timing is a band aid.

This platform is too focused on dyno numbers.

So it's coming close to that time of making a decision on which one to get... If I was to go with a Hi-flow cat I'd get the BM3... But since I really don't ever get on full throttle I'm think'in of going with MHD stage 2+ .... the EWG has a 4" cat compared to the PWG 3 1/2" .... I feel for as many times as I'll actually race it I'll be okay... but on that theory might as well get the BM3... Hmmm...

Get the BM3, the updates for MHD are taking forever..

Read this thread and both the MHD and BM3 threads and instagram, facebook etc etc (yes lots of reading) still no clear answer which is "better".

For me "better" means best OTS S1 and S2 tunes - power, reliability, drive-ability.

F30 335i PWG N55. MHD has price advantage but who cares about a couple of hundred dollars you should want what is best for your car. I'm leaning towards BM3 at present - seems to make more power mod for mod, dosn't have the torque limit issues in 3rd and 6th and much better customer support. Tell me if I'm wrong

MHD has resolved the torque limit issue as i was part of the beta testing but for the price i'd still choose MHD since i feel that BM3 maxes out the performance of the platform which could mean significant reliability issues in the long run. But I'm sure others will say differently!!!

[FastF30]

I'd say the reliability shouldn't be an issue with a stock turbo... or we'd be hearing PS2's blowing pieces all over the place...engine/ trans is good for 500whp being very conservative...600whp and your getting real close to the limit.... I see no problem that both of these BM3/MHD should not be running 11/12's in the quarter with a custom tune on FBO/93gas... seems that it is though... haven't seen any times in that range...

I still have a major torque limit issue with MHD

Have you contacted them to resolve the issue, either through Facebook messenger or email? Also, are you on the most current update for the app? What are the stats on your car? year, make, model, trans...

If anything post some logs on the MHD thread for further help

Also, i see you have a 5 series which i wasn't aware had any issues with torque limiter

[jgoens]

Been reading all the flash threads and considering going with one at some point instead of JB4 but I am still inconclusive as there seems to be fans on both sides. I'm also wondering about the power--does it knock you back in your seat like my JB4 running e40 does? I'm trying to legitimize spending the money on a tune when I spent $500 2 years ago on the JB4.
It's this forum that gives that mod itch.

I was initially going to go with BM3 but they were unable to unlock my ecu (2013 pwg) without an istep upgrade. So I went with MHD stage 2+ 93. Very happy very smooth. The jb4 felt more “full on/off” and inconsistent at times. Obviously an ECU flash works better than a piggy. Either flash will be better than a piggy and bm3 might be a little more aggressive with timing from what I read. The low end torque is crazy on the mhd

My 335i had a 11/12 build date and bootmod3 worked fine.

Not for me. Bm3 suggested I get bmw to update it or get it updated by a coder remotly.

[jeppe777]

Any update to this? is MHD still making less power?

[bradsm87]

Forget which makes a tiny bit more power than the other. Power has to come from somewhere and it's a compromise.

My point about MHD having better ongoing support has now been proven on the N55 F series platform. People have had 3rd and 6th torque limit issues for years. Only after MHD implemented a fix do PTF start thinking about implementing a fix. The same types of things will continue to happen moving forward.

Correct me if I'm wrong but didn't PTF introduce "boost by gear"? In any case competition is good for all of us so I'm happy

I can't speak for MHD but PTF's customer service has been top notch. They respond lightning quick and are always willing to help out should any issues arise.

From everything that i've read from the BM3 camp, customer service has been great BUT within the last few weeks to months MHD has stepped up there presence online, responding to concerns, inquiries and communicating future updates.

It is true and a bit odd that only after MHD started fixing/announcing the 3rd/6th gear limiting issues that PTF started to follow suit!

Competition is great for the consumer and community!

Not sure about your claim that BM3 introduced "boost by gear" and perhaps they have for the F-series N55. But MHD has been around much longer in general building and fine tuning other BMW platforms. So in all reality MHD has more tuning experience and presence from what i see and will only continue to push new features and map development in the next few months!

The only downside I see to MHD is how long it takes to unlock and map switch.

BM3 has it down to 3 mins 30 seconds for unlock and flash and less than 30 seconds for map switching as I can confirm that.

From what I hear it takes 25 mins to unlock, and around 3 minutes or 4 to map switch.

[TEST DRYVER]

Call Mike at Extreme Power! They carry quite a few tune/piggyback options. He's experienced enough and honest enough to tell you which he thinks is best for your end goal. That's the point here; what are you ultimately looking to achieve as your end goal? Is it max power or balanced and reliable power? Are you going to spend so much in suspension and brakes that your budget is limited for power mods at this point? After speaking to Mike and telling him my end goal for my wife's F30 N55 EWG, he recommended Active Autowork ECU tune or BM3. There were pros and cons to both (he also carries all of the JB4 and other brands as well). Since I wasn't planning on going meth injection or ethanol, he told me to research AA and BM3. End of the day, I ordered all the necessary FBO from him, and a BM3 stage 2 91 octane tune (since 93 octane fuel is not available in AZ, and getting 95 or 100 octane is a pain in the ass here and extremely limited). My car runs strong, I'm enjoying the tune, I like that I can switch to different parameters and sounds. And when I've had problems (when installing in the very beginning), BM3 was replying to my messages in the middle of the night, which is the only time I have to mess with this kind of stuff.
At the end of the day, would I of been happy had I chose to buy MHD or AA? I'm sure the answer would be Yes! Competition has kept them all on their toes, so I don't think you can go wrong with either, but I'm pretty satisfied with my decision... The only thing I would say, is that I believe a piggyback (JB4, DINAN, etc...) is dated technology compared to a flash tune. Not bad, just dated. That's why if you're currently shopping for the best tunes available for our platform right now, I believe a flash tune is the way to go. Don't crucify me for that last comment, it's just my opinion...

[harkes]

A good tune is all about the drivability. Who cares about power if you have a car with hiccups, rough idle, oscillating boost or a jerky shifting gearbox. Very few of us has an unlimited highway or drag strip on the way to work or the groceries. It must FEEL stock secondly it must add power.
