bootmod3 for BMW F series Vehicles - General Discussion

arvi604 · 06-19-2019, 02:48 PM

Can confirm shifts quicker and tighter for sure on our engine. Experience is overall pretty positive.

That being said, I had 3 occurrences with WOT on highway where the car would jerk/judder pretty violently at high RPM. It eventually triggered an MIL light.

I reflashed to stock, then flashed again then reset adaptations. Knock on wood, so far so good after that. I did send a support ticket with a log to PTF to see if there any underlying issues.

If anyone else got similar experience pls share.

So how does bm3 affect day to day driving? Is there just more power available everywhere? What about the different driving modes? How are they affected? I'm thinking the powerband is just increase everywhere with less lag.

Changes are pretty minimal according to PTF. Just increased holding on 3rd and 6th and slightly faster shifts. No real change in shift logic like the xHP tune.

Let us know what you think after you flash the TCU tune. The videos on their Instagram made it look like the shifting was dramatically quicker (it was an N20 328i). I'm gonna flash it the next day with decent weather...

It's differently quicker, I flashed mine on a n26 last night and shifts were much quicker and smoother.

Only got a little bit of driving in yesterday but shifts feel smoother and tighter. But I didn't get too much driving in. Might be able to get out tonight to warm the car and trans up fully and do some pulls, but not sure if I'll have time yet tonight.

Just watching closely.... I want to know how long they been running this TCU tune on a test car? Anyone have an idea just to make me feel better....lol

And is there any changes on the transmission behavior on comfort mode "D" position? Just for day to day around stop n go traffic LA street.

In Comfort Mode in "D" feels normal to me , stop and go shouldn't be any issue as far as i can tell. This isn't an aggressive TCU Flash, more of a clean up to smooth things out. Hope that helps from my look on it.

I didnt use an external battery. I have also flashed several times after DME unock with no issues.

I've never used one. I don't think it's neccesary, but it's good to have just in case.

You don't really need any supporting mods for stage 1. A charge pipe and a high flow air filter will get you going in the right way thought.

I've been running stock CP on stage 2 for almost 10k miles now. Don't want to jinx myself, so take that for what you will. No hardware mods are required for stage 1, and all you need for stage 2 is a DP and FMIC.

And no, stage 1 is definitely not a waste

It's a great bump in power over stock.

floridaorange · 06-20-2019, 09:19 PM

Also running stock CP - stage 2 since March, flashed prob 10 times no battery charger. Upgraded fmic and dp. Upgraded suspension made a big difference as well.

rjd_F30 · 06-21-2019, 05:59 PM

My thoughts on the trans flash for those curious: definitely a marked improvement in shift speed and crispness. Downshift rev matches are also legitimate rev matches now, far better than before. The downshifts sound just as clean as a well-executed MT rev match.

Also, manual mode is actually manual mode now. I did a first gear pull in M1, expecting it to shift at the top of the gear like usual, and it did not. It let me rev it all the way out until I let off. Kind of scared me, so just a heads up

Hello folks.

Running Bootmod3 stage 1, 91 octane tune.

I just moved back to east coast and now have access to 93....

Will I experience any issues running 93 with 91 tune?

Eventually... I will buy the map pack and reflash to 93 but thats a couple weeks out yet.

Using 93 on a 91 tune is fine. It just adds extra safety. Now using 91 on a 93 tune, thats a bad idea.

As CandyRedRC46 said, 93 on a 91 tune is just a little safety net, but 91 on a 93 tune is asking for knock.

Out of curiosity, where on the east coast did you move to?

Pretty minimal. The 93 tune is just a few more pounds of boost and maybe a few extra degrees of timing over the 91 tune. Maybe 10-20 whp? Just a guess...

floridaorange · 06-26-2019, 07:01 AM

The transmission flash was so clutch, pun intended. What a huge difference!!

Hi guys, I want to ask this question here first if someone has done it.. before sending email to PTF.

Has anyone tried to use enet cable to cellphone USB with adaptor? Does it work with the bm3 app?

I don't like getting that wifi agent. I like hardwire

Anyone else having odd issues with the iOS app? I flashed for the first time last night and took it for a spin and seemed good. Came back later and the app which keeps you auto logged in now says I don’t have a license. Had to log out then back in to get that reset. After doing a couple data logs I went to use the share link button and instead of giving me a link it loads the graph with a download csv button but doesn’t provide a URL to share or ability to get out of that screen. I have to close the app and go back in. Running version 0.10.074
