HC Performance are way too busy in most cases with actual bm3 support. I like Sameh and F80Paul from all I’ve seen and heard. Botti is too green with bm3

My only point for posting what I did is to respond that BM3 writes the whole dme as you said its just calibration. Also BM3 has had this for over 2 years and this Femto thing was their 2nd update they did since then. MHD has teased they’d do it since way back then too but never actually did it.

They got what they call a Rev2 board coming. They are posting about it on their Instagram. They used it to tune a 1200+ whp B58 and now doing it with a G80 M3.

BM3 writes the whole entire DME and change software too not just tables/calibration. This is how they add all the crazy nice features called CustomROM that they released for things like map switching using the steering wheel buttons, flex fuel, antilag, etc.

It doesn’t overwrite anything if you’re doing map configuration changes. You don’t need copies of maps.

I never had a single issue with it

Mine works solid but I know some mentioned on F series have an issue and you can go to previous firmware. Go to the Wifi screen and click on bottom right menu called Firmwares and click on 1.14 or 1.14.2 and update to that. That’s the original. I got this from an F series dude that had an issue...

bm3 has their own rev2 board coming that’ll blow this reflex thing out of the water. They’ve been hinting at it last few posts on Instagram. Reflex has also seen so many issues recently its crazy with people reporting it restart mid pull, eating battery, etc. Maybe they got a batch of bad boards...

You don’t need to activate a bm3 license anymore. You can just send the DME over. I checked with them on this last week.

You have 7 graphs in there bro. Of course it won’t look “clean” as you got lots of lines in there crossing each other plus they didn’t post it like others with full smoothing to fake out additional smoothness.

Its a stock cams car and no other graph I have seen posted anywhere looks nearly as clean. Lets be honest. Plus they didn’t use smoothing of 5 which would make this look even smoother.

If you’ll wait then you could also wait for the BM3’s Rev2 board.

Doesn’t really matter which slot you choose. You typically choose the slot which most closely matches your standard pump gas that you fill up with and the tune turns it up from there when E is in the tank.

They are doing more with the car, cams change. I think they want it all on the car first then go beat on it and dial in stuff at the track. I’m sure it’ll take some time to get the car figured out how to launch etc

Sounds like femto did a basic unlock for you and not custom rom one as otherwise it works.

Bm3 just mentioned on their 1200whp b58 instagram post that they are controlling PI and boost with their own board called Rev2. That car is craaay btw!

You’re doing something wrong bro. Email them for instructions

All works. What can’t you get to work? Probably doing it wrong

Can’t use that, its an older one

I’d never again use cables with mobile phones. Get the BM3 wifi adapter for your phone. It works best by far.
