HC does also offer custom tunes...so any conflict of interest exists between both platforms and the people who do their tunes (although from use of both - neither one is making a bad OTS tune to try to get you to use their custom services)

I will note that when I was using BM3, the support on the tunes was absolutely incredible, and led to the development of some new features. I worked directly with BM3 to develop and test the throttle mapping sliders.

bootmod3 are the tuners and the programmers. They create the bm3 maps and the software.

MHD are not tuners; they buy their maps from third-party tuners. in my opinion, it creates a problem with support, given their limited tuning knowledge.

It also creates a conflict of interest with the third-party tuners as they want to sell you a custom map, if they make the best possible map for MHD then they won't have a custom map to sell.

I have BM3 on both of my cars. I sometimes doubt they are the tuners. I don't understand how on both vehicles the 93 tunes never can actually run on 93. Winter or summer gas, the 93 tunes pull timing. So in order to run a 93 tune, I need to put in e20. Doesn't make sense from the expert tuners.

Ive also submitted logs in the past and the advice they have given me was nonsense. I ended up fixing issues on my own, contrary to what they said was wrong.

I think the real answer for the M340 is ECUtek which I may switch to.

Totally off topic here - The ECUtek tuning guide is a really great way for people to understand how our cars work, and what some of the more advanced logging channels mean.

I learned a lot from reading that.

Correct me if I'm wrong but ECUtek is software that "tuners" can use. ECUtek in and of itself does not offer "tunes" So your tuner can use ECUtek to tune your car but ECUtek is not a stand alone solution - is that correct? And if that's the case isn't ECUtek, BM3, and MHD all in the same boat in the sense that they all offer a software solution to load a tune but none of them are providing their own off the shelf solutions?

Don't mean to light you up and position you as the expert - I'm just trying to understand - please anyone else jump in here for clarity's sake thank you

yes thats correct. ECUTEK effectively is only custom tunes. BM3 & MHD are platforms that can be used to custom tune, however from what I understand there is less control for the tuner.

My logic is that if BM3 and mhd OTS maps are not good and I need a custom tune, why not just get the platform that allows for the best result.

I am still trying to figure out the best route for myself. What I can tell you is that Bm3 93 tunes are bad. I have 1 gal of e85 and the rest 93 and pulled timing on all logs on this tank.

What you think and what is truth are totally different things. BM3 are highly seasoned tuners that have been around for years. They do all their dev in house and have all these cars and dynos also in house. Fact your neighbourhood octane quality is low doesn’t mean anything other than your hood’s octane sucks.

Is EcuTek compatible with the FEMto unlock?
As far as i know it´s only compatible with the FEMto OBD2 Flasher and bm3, MHD, MG Flasher.

Not for our Mild Hybrid cars. Ecutek doesnt support femto unlocks. You have three choices- bm3, mhd, mgflasher

From what I read on these forums, most users cannot clean timing with the 93 maps. OTS maps should be optimized for the mass, not for the few.

Like I said, their tech support has also been wrong in the past. Also I question their recommended plugs and gap.

Anyone here running an AA catted DP with MHD stage 2? Thoughts? Concerns?

ThNk you in advance!!

You need to be more specific; what are your concerns?

the AA and MHD are both proven to work well without any major concerns.

I’m using an OTS 93 map. How do I check if I’m getting clean timing?

Check the ignition timing correction on each cylinder in the log. You would want the correction to be zero degrees or close to it.

Here's my log after a short and pretty sedate drive. Does it look good/bad/average?

From a novice perspective, it mostly it looks like the timing correction is zero, but there are some points where it spikes - but I'm not really knowledgeable on this kind of thing.

BM3 Stage 2 E93 OTS, along with XHP Stage 2, sports cat downpipe.

+1 on a BM3 stage 1, 93 octane tune pulling timing. It happens in temps above 90’F

This log doesnt look right. Im on my phone so hard to see but did you do a WOT pull in 3rd gear through 4th gear? Need to start at 3k rpms in 3rd and then floor it all the way into 5th.

No. Didn’t do a WOT pull at all. It was pretty sedate driving - my bad, I didn’t know that was what you were meant to do. Will do one and re-upload in a few days or so and share the logs… just wanna help people know if the BM3 map has problems or not.

I tried to do one again.

The first one was a good opportunity, good run through some gears, and does show some timing corrections, not sure if they are good/bad

https://www.bootmod3.net/log?id=643c...0b431263ec7f5d

Note: It wasn't quite WOT. I didn't realise at the time but I must have lifted off a little.


I also tried a second time but had to lift off due to someone changing lanes in front of me. It was mostly WOT, but only only until the gear changed to 4th.

https://www.bootmod3.net/log?id=643c...729b710de1cfdb

I'd appreciate your (or anyone else's) thoughts. Is that an unacceptable amount of timing correction?

There was no knock's detected on either of them, but noticed there was one in my third attempt at a pull - where I also had to lift off again. Roads too busy today.

Update: BM3 team have suggest moving to the 91 map, even though I'm using 99 Octane fuel. It still had timing issues, so they've advised to reduce the boost pressure target, which I've done a few times and yet to try the latest settings (20PSI)

[Wet Fish]

Update: not impressed with BM3 support.

Whilst they are responsive, I think they are deflecting from the issues in the OTS map.

Initially directed me to the 91 map (rather than 93) despite me using 99 fuel and STILL had timing issues. Told to reduce pressure target twice… still having issues (and oddly it didn’t show a reduced pressure target on the logs).

They are putting it down to fuela and asked me to try a different one, but I’ve tried Shell v power and Tesco momentum which are both 99 octane and I think the only suppliers in the UK.

So not much hope of getting the stage 2 map to work. I’m wondering if I’ll get timing on stage 1 at this point. Very disappointed so far.

Hello, I have to admit that I am hesitating between MHD, Mgflash and bm3, and reading the concerns of the BM3 after sales service I think I have eliminated it from my choice, thanks to you for your feedback that helped me

Isn't the octane rating different from EU to NA, for us it only goes up to 94.
