Log for M340i

[AlexArev]

Map 6 at E30ish might be higher. Low rpm close to redline at WOT

[Steve @ BMS/Fuel-It!]

Looks pretty good, set your FF to 45 or let it learn up to hit boost target.

[AlexArev]

Great, Would I benefit from running port with the jb4?

[Steve @ BMS/Fuel-It!]

Not until your HPFP begins to struggle. Thus far it's not but ifr you plan to run a flash and E85, then it will likely crash.

[AlexArev]

I stand corrected, this is map 5, can I get this to go any faster?

[Steve @ BMS/Fuel-It!]

Per my previous response, the first thing to do is to set your FF to 45 and see if you can hit boost target. If you want to play with map 6 and enter your own boost targets that's an option as well but I don't typically recommend that unless you can read logs, change JB4 settings, and verify everything looks good. That's typically reserved for more advanced users.

[AlexArev]

Heres a 3rd gear pull, with FF set at 45 on Map 5

[Steve @ BMS/Fuel-It!]

This isn't much of a log...


Do logs from 2K rpms to redline in 3rd gear and then shift in to 4th on a safe and private track. Logs need to be longer for adaptions and analysis.

Thank you

[AlexArev]

My apologies, Heres a proper 3rd gear 2k Rpm-Redline🪵

[Steve @ BMS/Fuel-It!]

Looks pretty good, FF will probably learn up a bit or you can manually set it to 45.

[AlexArev]

Yeah for some reason it keeps changing, I manually set to 45 and go back to it and itll be at 50.

One more question can I run Meth on Map 5? Do I have to set up settings on the jb4 or is it automatic.

[Steve @ BMS/Fuel-It!]

It's supposed to change so that is fine.

You can, but I'd recommend running the meth map to retain the safeties. Map 5 won't have those safeties.

[AlexArev]

Am I able to run Straight M1 or is a 50/50 recommended for the meth map.

[Steve @ BMS/Fuel-It!]

I prefer straight meth or straight ethanol myself.

[AlexArev]

What do you recommend for max power on a stock turbo. Ethanol or meth

[Steve @ BMS/Fuel-It!]

You can run either, the turbo will be the limiter.

[AlexArev]

Boost Additive 75
signal scaling 60
50/50 Meth
Wastegate adaptation 45
Heres a log 60-130, definitely slower than Map 5 with no meth. Well see what you think

[Steve @ BMS/Fuel-It!]

Put everything back to the default settings. FF is too low and your DB's should all be 50 (although 0 is affectively the same thing). Your meth does not appear to be working either so you need to verify that.

Also, do normal logs, log should not start at 5K rpms, they should start at 2K rpms.

[AlexArev]

Is there a button somewhere to put default settings, I cant find it

[AlexArev]

Im able to purge meth, and its firing through the nozzles. But im not sure if its firing when under boost.

[Antec800]

Hey Steve can I email you logs

No, you have to input them manually.

It's best to start your own support thread rather than jump on somebodies...that confuses things.

Sorry I tried dming but it wouldn’t work, can you message me your email

Alright steve, Ive reset the settings, but with a custom map 6 i cant seem to get over 22psi. Any suggestions on settings to move, Duty Bias is at 50, FF at 45, Meth Trigger at 1.

[AlexArev]

Heres a Map 5 starting at 3k rpm to redline, can you confirm if the meth is working?

[Steve @ BMS/Fuel-It!]

Try bumping FF up to 60 and it does appear meth is working.

[AlexArev]

I wonder why the car runs slower with meth, just cant seem to figure it out.

[Steve @ BMS/Fuel-It!]

In this log you weren't hitting the boost requested so that's why I told you to increase FF to 60.
