With 2 more years left in my warranty I went ahead and installed the bootmod3 Stage 1 91 Octane OTS tune. Just could not wait that long.

My car is all stock down to the last nut.

Will be doing some 0-100 km/h comparison runs like I did earlier with stock and JB+. Now with bootmod3 in the picture we'll get some good data.

After getting tuned with bootmod3, the feel and connection to the car is sublime. The feeling of being one with your car is the best way to describe it. It feels lighter and more responsive.

Stock had smoothness. JB+ had power. bootmod3 has both in perfect harmony.

Stay tuned. Pun intended.

Ditto, my warranty runs out at the end of June.

Also thinking about catted downpipe, but will stick with Stage 1 95 Octane

I have had BM3 stage1 93 on my 18 F31 330i for about 2 weeks. Installed a Burger Motorsports intake and a dual exhaust from a M235IX in past week. I feel like I traded my car in on a M car lol. The feel, the sound, it makes me feel like I did when I was 20 again and I bought my 72 340 Cuda.

I have a question regarding the installation of the BM3 wifi agent in my 2017 LCI F31? My OBDII port is behind a flap, how are people installing permanent OBDII cables? Would appreciate pics?

Thanks,

Ian.

Hi there,
How long it takes to make initial flash via WiFi agent (e.g. Vgate) from mobile phone?

Takes like 3 minutes but you can also now with their beta version of the app use the phone with an enet cable directly too.

Great, thank you. The problem is that I don’t have ethernet to obd2 cable at all, so wireless flashing only possible in my scenario

With my service warranty ending soon, I'm going to tune my stock 2018 F32 B48 430i xDrive 8AT and will be adding:

BM3 Stage 1 (to start)
ER Catless DP
ER Chargepipe
Injen Intake
Full exhaust, (AWE Axelback Touring Single Sided + AWE Performance Midpipe Resonated)

To do later:
19" wide performance wheels
BM3 Stage 2
heat exchanger (necessary for b48?)


Hoping to get to 300whp and 330wtq without breaking a piston and keeping it reliable while I wait for the BMW Supra GRMN / M2 CS with the S58 for my next car...open to any suggestions

Any hope for a B48 8AT transmission flash? When I go to the OBD agent and click transmission, it is just greyed out, perhaps because they only exist for N series ZF 8HP45 and not the ZF 8HP50?

Map is on version 2.1 for the B48-F-H (20i) engines, I presume.

For the B48-F-L (30i) engines, the map is on version 2.0.

Can BM3 help code in the support for GPF /OPF delete for those of us which are unlucky enough to have the GPF /OPF and sensor that monitors it?

The OTS for Stage 2 with 91 Octane typically asks for a modified intercooler, downpipe..

Does anyone know of a performance intercooler for BMW F30 330i B46 engine? I did not see anything online.

The intercooler req is for N series engines

The stock charge air cooler (air->water->air) that comes stock is plenty capable of handling stage 2 on a B46
