2021 m340 xdrive map1 log please review

Please review map1 log. New to this….. Currently running pump 93 only other mods are BMS billet intake..AWE non resonated touring exhaust…and ewg connected. Recently changed fuel and no octane booster yet(ever). Eventually want to run e30 or e40 but that would be on occasions due to availability. So can I go to map2 or map3. Or is there any user adjustments that I have to make with firmware v20. Thank you

Logs look pretty good other than the top end timing. Your change to e30 will help with that.

Great. Thanks. So I ll try some octane booster maybe and go to map2. When I do run with e30 I go with maps 4-5 ? And all the user settings that you can change…I was just wondering about if or when that gets tapped into. Thank you

Steve @ BMS/Fuel-It! 12-08-2021 11:05 AM

Add a bottle of octane boost and do a log on map 4. There shouldn't be many user adjustments that need changed, if map 4 looks good, we'll proceed to map 5.

Map4 with octane booster

Heís a couple log on map4. Not the cleanest so will do again if needed. Thank you

Looks pretty normal...a few small timing corrections but nothing to be concerned with. If wanting to go to map 5, do a proper log on map 4 for review and we can go from there.

To properly evaluate the tuning, we'll need a full throttle JB4 log from 40-90mph on a safe private track.

Hereís a descent map4 log I hope and if you think I can Iím ready for a e30 mix. Finally found gas station about 40 min away which isnít bad I guess. So got 10 gallons but wanted Steve or who ever else to look at map4. Please let me kno. Appreciate all the help. And if I should change spark plugs. Thanks again

Cannon @ BMS 01-21-2022 04:10 PM

Log looks good still. Go ahead and try E30 and upload another log. Getting plugs will help with timing corrections and/or blowout as you increase boost. I will link the kit below that has all the proper plugs and tools you will need for the install.

Steve @ BMS/Fuel-It! 01-27-2022 01:06 PM

When doing logs...be sure to stay at WOT. I concur with Cannon, the E30 will help clean up timing a bit.

Jtm340 01-30-2022 01:28 PM

Yea I will do that. Keep it wot…..I had a E30 mix this past week but didn’t get chance to do some logs. Def will get those logs in next weekend. Gotta say the but dyno feels great with the E30 on map4. Can’t wait to see what it looks like and what map5 brings. Just wondering tho…before I got the jb4 I asked Dave from BMS if anything is possible to do if you prefer more torque or low end power. Does anyone kno if something like that is possible without the backend flash. Since I can’t do that yet due to +06/2020 ecu. Like I said. Was just wondering. Will post logs as soon as I get them done. Thank you again. Conner/Steve and everyone else with there input. Thank you

Steve @ BMS/Fuel-It! 01-31-2022 06:28 PM

@Conner :lol

Spool looks pretty normal to me, I don't see excessive lag.

Jtm340 02-05-2022 03:39 PM

sorry for the delay with my logs....found out one of my rims has 2 nice size dents so i have to fix that before i put in my map4 E30 log...will be coming soon
