Bimmercode is now working with G29 in case you want to turn off ASD, and other things

BIMMERPOST
     Featured on BIMMERPOST.com
Just got an adapter and gave it a try. Turned off ASD so it didn't mess with the audio (just upgraded the sound system and found that the ASD sound also gets amplified). Pretty stunned at how quiet the drive is without it, and how much it adds...

You can see a full list of features enabled at the moment for the G series cars, and they keep adding things to each beta version, so soon it will support as much as it did for the F series.

You can also sign up for the beta version on the app store (scroll down towards the bottom of the description, so you can get access to all features ( I had to get the beta to access ASD functionality)

It works on both Android and iOS. I had an android tablet, so went that route as the adapter is cheaper for android devices.

If anyone is in or near LA, you're welcome to use my adapter and app if you want to change a few things.

Turning off ASD was the sole reason for me getting an adapter and bimmercode. I like quiet cars. Then I started coding everything else that I liked. Hoping my adapter works on G cars since that's what I'm looking at next.

I got the MHD wifi ODB connector. Works great. Coded video in motion, start screen warning off and volume pop up off. Thought i could tune my car using MHD tune app but no maps available for M40i USA version. MHD website not clear on that.

Sorry you got stuck with MHD like that. Their website shows G29 support. Did you try contacting their support or your seller for a refund?

I can vouch that BM3 does indeed work on US Spec Z4 M40i. I have their stage 2 map (version2.1 currently) flashed. Only issue I have is my remote start no longer works.

It doesn't look like flashing brake force display is available?

Has anyone coded anti-dazzle?

I'm happy with the MHD ODB connector. Very fast works with bimmercode, so all is not wasted. Just wish MHD maps for USA were available. Yes website says supported but thats for EU only.Complained about it but no correction. They say logging is supported but big deal!They mentioned something about beta, but i'm not going to be a guinea pig. Not on a lease. I ordered a JB+ in the meantime. I will check out Bm3 . What are gains stage 1

Turning off asd. Share your experience. Does the sound system sound better?

Canít say anything about stage 1 because I havenít flashed it. However, based on the stage 2 experience, I wouldnít doubt its a step above the factory tune. More power throughout the power band without having to over press the accelerator to pass

Went on website. Little info on power gains. Did you tune it yourself? I assume you have a downpipe? No warranty for you then

Yes I tuned it myself. OBD cable and a laptop and done in 5 minutes. Have a catless downpipe. However, DP alone doesnít void warranty. Itís the flash tune that will void the warranty. MHD would do the same thing. Any ECU flash will void your warranty.

Their website doesnít specify expected HP gains as a figure because each engine will perform differently due to operating environment. Instead, they specify expected percentage change over stock because of how BMW programs their ECUs based on power output thresholds instead of set parameters. Meaning if the output threshold is 15% and based on the operating environment it can reach that with less boost/more timing (or visa versa), then it will do so. Because of this, they canít say ďexpect +40hp on stage 1Ē because it may be +30hp for one engine, and +50hp for another.

For example, an engine operating near sea level has normal air pressure/density to work with. Therefore, it may produce 380hp at the crank under these conditions. If the threshold is Increased by 15%, it only needs to work a little harder to reach that goal, netting a +57hp increase. However, that same engine operating at 5,000 feet may produce 345hp, but with the increased threshold set to 15% still, it has to work harder to reach that threshold, but ultimately does netting an increase of +52hp.

I"m sure the downpipe would not interfere with your oil change or other warranty work. But any engine trouble its a dead give away. Had engine problems with MHD and dealer never saw the software. I erased it before dealer visit. (previous Z4).I was under the understanding Mhd can be completely uninstalled. I could be wrong. Why no remote start after tune?

Had a turbo replaced under warranty on my last bmw with an aftermarket downpipe. Didnít void the warranty at all. And Bmw can detect a flash tune if they really wanted to. Flashing back to stock doesnít negate the shadow counter for the number of ECU flashes performed that they can match against their records. They may not have dug into the ECU during your engine trouble because it wasnít worth it. If you needed an engine replacement Iím sure it wouldíve been looked at. BMW has been trying to fight flash tunes for quite some time with enhanced encryption. As soon as the ECU is cracked, BMW looks at the exploit and then patches it and puts out a service bulletin for an ECU flash. Itís a never ending cycle.

And yes, the Supra is getting over 500hp at the crank estimated. Different engine than the one in the z4 M40i (until the 2021 model year Supra). And itís not on straight 93 octane fuel. Theyíre running e30 or even e85 and theyíre custom tunes, not OTS tunes. Iím positive my stage 2 93 Octane OTS tune is 450+ crank hp because Iím pulling c6 and c7 corvettes that weigh less and are rated at 450 crank hp. Just havenít had time to swing by the dyno to get numbers yet.

Great info OP cheers. Just out of interest BMW is learning about ASD. On the F40 1 series there is an option to toggle between:-

- Full ASD
- Dependant on driving mode
- Reduced

Great to see this out of the box and my point is I think all future models will have that and maybe even a S/W update on the G29.

If you wanted to see this in the states, have a little look around the new F44 2 Series GC (dont be rude ) as I know you don't have the 1er there. OS7 feature is 'Engine Sound'

I still really want a Z4 but work doesn't allow it just yet. Pah!

But anyway, no one will ship the OBD adapter now due to COVID19.

That not just me in Hong Kong. Seems all ID7 in Hong Kong did not activate the album cover of the MP3 music.
My same music files have album cover display in my Mercedes Benz!
