Bm3 vs mhd vs aa

It's probably too early to fully discuss the pros and cons of the these three obd tunes however is there anything on the surface that jumps out?

It seems like the only apparent difference right now is thst mhd will be cheaper?

All three will offer dp cell turn off. Removal of the cat warm up cycle. Burbles. And the ability to switch maps. So in the end as a consumer what's the next data point that will help you make a decision? Will it come down to posted dyno sheets and which is making the most power?

If you have pulled the trigger on one already please share you logic on making that choice.

Gotta love options! I just placed an order through x-ph for bootmod3 license, intercooler and downpipe. I already have a charge pipe and m performance exhaust.

I went with bootmod3 for the following reasons:

- very popular on the site, so is clearly well established in the tuning community. Also the Facebook group is active and friendly for troubleshooting
- iOS, windows and android support
- OBD unlock and flash via ENET cable (I already have one)
- proven results

Ultimately it came down to having the most proven tune (AA was the only other option to me that was proven on this platform) and then total cost and ease of use, where bootmod3 wins for me.

I'd like to get a before/after dyno but the nearest AWD dyno is 200 km away so I don't think that's gonna happen.

Psi will tell you very little without ignition timing. Even dyno charts will be comparing apples to pears.

For both MHD and BM3 maps will be in constant development - don't know about AA.

AA does not include future map updates to my knowledge.

BM3 might have a little better OTS maps than MHD as it's had a year head start.

MHD has a brighter future in terms of future features, logic changes etc. It's also fully open allowing backup of real Bin file and editing of real BIN file with whatever software you prefer.

MHD wins for me.

I really love BM3. Guys have been non stop adding new features, have been out first and for a long while now with proven results and they keep adding more all the time without additional costs to features that many would charge extra for. Like a gift that keeps on giving. Their support is nothing short of stellar to and you can reach them anywhere. The new offline flasher is crazy fast to switch a map its literally like 30 seconds. I love their Facebook group too as its just a bunch of guys providing helpful advice and just being real. Can’t go wrong that’s for sure.

I went with BM3 because at the time it was the only bef available. It's awesome. My experience so far...

1. Customer support is freaking unbelievable. I got my DME unlocked on a Friday evening in LA, so PTF was already closed by the time my DME was unlocked. I reached out to Dzenan through FB and told him I was going to a car meet/cruise Saturday afternoon and really want to get the Stage 2 map loaded. At the time you had to wait for the map to be provided to you and then do logs so they could dial it in. Now it's all automated and the OTS maps are solid. Anyway, he took time out of his Saturday to get me all squared away. I was truly impressed.

2. Constant upgrades to the software and updates to the maps which are all free of charge

3. Proven record and results. I put down some pretty good numbers with crappy California 91 octane.

4. Like stock drivability

5. Solid tuner base

AA includes (4) different tunes of your choosing in the cost which you can get at any time after initial purchase - you don't have to get them all at once...

No worries. Your MPPK will be saved as your "stock map" and you can always revert to that should you wish so.

I went with MHD because of the opportunity to become a BETA tester. I love it, flashing from your phone is amazing. also from what I understand the maps are done by PureBoost so they are not new untested maps. I've seen around 16.5 psi on my car(stage 1), have not been dynoed. you cant really estimate power from psi but it is a huge improvement over stock.

harkes mentioned it above and I'll mention it here.
From how I understand it boost numbers really don't tell you all that much.

Quick for instance; one major factor is altitude, we had a member in the PWG beta group hitting upwards of 18PSI, why? He lives on top of a mountain. Air is less dense, needs more of it to make same power as you would at sea level. Is he making more power than I am with 13PSI at sea level? Probably not.

There are many other factors but yea that's one of the major ones.

I'm going to keep saying this, timing is very important and often overlooked. I explain a bit in my latest blog post if anyone is interested.

Just my $0.02

You could be hitting 18 psi but pull timing and make less power then someone hitting 16psi with timing advanced....just saying.

At the time I made my choice MHD was the only OBD flash available of the 3. Not to mention the price point, in beta you pay $250 for license and $99 gets you all the map packs stg1, 2, 2+ so you can switch and test which one you like. If you want logging it's another $99, that's $450 all in. I emailed other tuners that advertised OBD flash and one didn't reply and the other said due to high demand they are only working with M3/4 customers at the moment. I have a 2014 435i xDrive EWG FBO, running MHD STG2+ 93 oct. I am extremely satisfied with the flash. Very easy to do at home. The power is unbelievable the car runs smoother and better than stock. When I get on it hard it squeals the rear wheels even tho Xdrive. They also have a WhatsApp group chat set up so you can contact them and other users directly to get support, tips or voice concerns. It's really a quality product.
