I'd reiterate what BorneATeste said. I found the 1.6 maps a bit more binary (harsh on/off) at light throttle cruise. This just flows power smooth like stock and pulls hard.

It still locks up the seatbelt pretensioners giving you a sh*t eating grin.

Flashed and took for a quick drive, agree with all above about the smooth power delivery.

just put e30 tune on mine...made a huge difference from 91 octane! .3 sec and 3mph in the 1/8th mile better on my first pass.

Question. I'm not familiar with E30 but we have 94 octane fuel here so would that be equivalent and be a good option to run with the e30 tune?

no!

e30 is a blend of e85 (corn fuel; 100+ octane) and 91 or 93 octane gas.

you mix the blend until it's about 30% ethanol, and then you can run the e30 tune.

for a 16 gallon tank on 91 octane; it's 4.25-4.5 gallons of e85 and 11.5 gal 91 octane

Ok thanks for clarifying. Way too much hassle every fill up for sure!

Does anyone know if version 2.0 is still the latest or is there another update? I have a 2018 340i manual and I would say 1/4 throttle was full boost in v1.6 and in v2.0 it's now 1/3 throttle, so it's an improvement, but still very abrupt if you're anywhere between 2500rpm and 4000rpm. Even with the throttle cracked, the boost will just hit once you get close to 2500rpm. I also have a very slight lag after shifting and the hanging rev problem everyone seems to have where it continues to throttle a split second after letting off and pushing in the clutch.

[Wires]

You need revs for it to build boost (around 2500-3000RPM with part throttle from what I see is where it starts to pull). If it's hot outside and you are doing a lot of stop/go, high IAT temps well increase bottom end lag, which you'll feel as that dead spot to a sharp power transition.

BM3 just increases the power so it amplifies the stock effect of this.

I have a 440 rwd, bootmod3 stage 2 version 1.6. I do 100-200 in 9.6 seconds. I see that much slower than other colleagues. (I have automatic change) how can i improve it? Do I try version 2.0?

Yes it's faster. You also may have other problems. Post logs and we can see if something's wrong.

Does anyone know what the current version is? I am on 2.0 now.

Still 2.0.

Halim@HCP any B58 updates on the horizon?
