Hey guys, long time lurker here.

Just took the plunge and got BM3 w/ a Stage 1 93 octane tune flashed onto my 340i.

Stock sparkers at 30K on the ODO.


Here is my log [3rd gear pull]: https://www.bootmod3.net/log?id=6008...729b1b88e8fc0f

Would anyone be so kind to pop in there and take a look to see if everything is in line for a BM1 Stg 1 93 Octane tune? Thanks!

I've got the 1 step colder NGK's waiting to go in this weekend, from what I've been reading leaving them at stock gap for a stage 1 would be fine. Anything in this log that might indicate otherwise?

Your timing is pretty low most probably fuel not exactly 93 octane, my guess you will need to use 91 octane tune.

Do another log preferably in 4th gear and make sure you add timing correction to your parameters when logging.

Thanks for checking it out! I too thought the timing looked low considering. I enabled the timing corrections in BM3 and I'll re-log tonight.

It's got a full tank of 93 Chevron in there but I did put a bottle of Chevron fuel injector cleaner when I filled up last week but not sure if that lowers octane rating any.

Either case, will re-log and post later! Thanks!

It looks ok nothing to worry about, cyl 4 is not pulling timing in 4th gear.

It seems you had a wheel spin between 3400 to 4400 RPM in 3rd gear, better log in 4th gear all the way to 6500 RPM.

Car pulls very clean and made an extra 35 lbft low through to mid range over Stage 1, I'm not too hot on reading these logs but seems cyl 4 is pulling timing at 4500rpm?

Cheers!

Hi Everyone i'm pretty new to tuning and just wanted to make sure everything was ok with theses logs.
only mod i have is a catless downpipe
2016 340 drive with 54k
i see a little bit of knock but it seems to be .1 so not too sure if that's normal
Any information will be helpful! thank you
93oct

Hey, do you have any WOT logs in 3rd or 4th gear?

This seems to be a partial throttle log cruising log.

Looking good mate.

Sorry forgot to tell you this, also add timing correction in the BM3 log parameters.

I am not sure why BM3 are not enabling timing correction by defaualt in the logs they are very important.

I made an introductory guide to help people understand how to read their logs. I've added the Youtube video to the OP hope it helps

Hey there! Finally got around to doing a 4th gear pull: timing still seems on the low end and large corrections up top, you thinking the same? Probably not getting actual 93 octane from the last fill up.

I'm changing my plugs tomorrow from the stock champions over to the NGK 94201's and I was thinking of putting in 1 gal of E85 and top off with 93 octane to make an E15 mix. Thoughts on that?

Hi Guys, I've flashed my car since Nov 2020 and have only got the chance to log it today. It's flashed using Stage 2 91Oct OTS map and Stage 2 XHP tools.

Hardware update (Spark Plugs are new, still using OEM):
- AA Catless Downpipe
- MST Open Air Intake
- Eisenmann Race Muffler

I feel like my ignition timing are not the best under WOT, seems like Cylinder 1 is pulling timing; need the experts input here... Here are some WOT 3rd-5th/6th gear pulls:
https://www.bootmod3.net/log?id=600c...90c662d69ccb7e
https://www.bootmod3.net/log?id=600c...729b5687b673f4
https://www.bootmod3.net/log?id=600c...90c6636ad8a48b

On top of that I've also logged the car under "Comfort" driving in lower speed/lower RPM -- and it records a lot of knocks (see below logs)... Is this normal?
https://www.bootmod3.net/log?id=600c...729b5687b673f5
https://www.bootmod3.net/log?id=600c...3c0b59967ad228

Thanks so much in advance guys for the help..

Note: Sorry I did not know I need to add Timing Correction to the log too, just realized its not there on the default setting by BM3.. Will try to log it again sometime soon..

Sorry to ask another question.. Do the BM3 datalogs have any option to detect Boost temperature or Charge Pipe temperature? I cant seem to find it..

Because Im wondering whether the spiking Boost temp is the culprit of the timing pulls?

It is "Intake air temperature before throttle measured" in the Other Channels.

But DME already takes IAT (air temp right atfer IC) and Coolant Temp to calculate an igntion compensation (e.g. -2°) to apply to initial ignition target (e.g. 10°) to get a final ignition target (in this case it would be 8°).

Thankyou bro. So it will all goes back to the 'timing correction' parameter then I guess ya? If it is more than -2° than it is not good?

Gonna make another pull soon with better parameters, so hopefully we can find out what causing this knocks at low rpms and timing pull in the higher rpms..

[F80Moe]

On my B58TU (Supra) on Pure800 + Meth

In 5th gear

When my car is cold - Boost target is around 23psi

After driving around for an hour or so..

When my car is hot - Boost target is around 28psi

IAT, oil temps, coolant temps are all the same..

The ONLY difference is fuel temp in LPFP (36C vs 60C)

Feels as if octane is low because of high fuel temp and car ups boost to reach targets..

I have tested this several times.. Has anyone come across something similar?

My targets change at most 1-2 psi. I don't do logs when the car is cold though, doesn't seem like a good idea. If anything it's running a "protection" map until the engine gets up to temp.

Hi all,

Would appreciate some feedback on my log, the car is a m140i RWD and the pull was done in 5th gear

Im running tesco momentum 99 ron fuel below are the mods

MHD stage 2 98 ron
XHP stage 3
200 cel sports cat
BCS mid pipe
M performance exhaust
Injen evolution intake

The log is showing timing corrections upto -4 right through towards the redline and the knock -1.2 isn't good.

More octane would be needed to run that tune with clean timing and zero knock.

I would flash the 91/95RON Stage 2 tune and post a log.

Also, I wouldn't log in 5th gear from 1800rpm. Putting high load at low rpm isn't good on the engine.

Better to log in 4th/5th gear from at least 2500rpm.

[b7ff]

Finally did my run with the correct parameters.. The first few pulls shows that Cylinder 1 Correction is >3 degrees all way to red line (typical BM3 OTS map problem as @kern417 points out earlier in this thread).

Interestingly however, in my last 3 pulls - timing corrections are rather improved compared to the first 3.. Need your input, is there anything that I need to be concern with these data?

Am not planning to do meth and custom tune currently; will adding some octane booster helped? Btw this is a Stage 2 - 91 Oct tune but Im already running 93 Oct fuel right now.

1st Run (3rd Gear): https://www.bootmod3.net/log?id=6016...90c6636ad8be9b
2nd Run (4th Gear): https://www.bootmod3.net/log?id=6016...0b4320bdf20323
3rd Run (4th Gear): https://www.bootmod3.net/log?id=6016...729b5687b68d7d
4th Run (3rd, 4th Gear): https://www.bootmod3.net/log?id=6016...0b4320bdf20324
5th Run (4th Gear): https://www.bootmod3.net/log?id=6016...729b5687b68d7e
6th Run (3rd, 4th, 5th Gear): https://www.bootmod3.net/log?id=6016...90c6636ad8be9c

Should I send this data to BM3 and ask them to revise the tune?
All inputs will be greatly appreciated guys, thanks guys!!

Logs aren't looking too good, does anyone else have a problem with hpfp dropping significantly from target on this ots map? Seems to be consistently right around 3k rpm in the logs. Timing doesn't look good either..

BM3 Stage 2 91 ACN OTS

Fresh tank of shell 91 (California)

Log starts at 4th gear 2k rpm, wot to redline and including a shift.

Remus catback
AA catted dp
XHP stage 3
AP intake
Factory equipped sparked plugs with just under 11k mi on them
Stock b58 gen1 hpfp

All 3 logs included in a datazap:

2 stock tune (XHP stage 3 still installed) logs:

LOL. how about this HPFP drop off?! I just installed the tune and this was my first data log. Ugly!! Do I need to upgrade the the HPFP already? I installed new coils and plugs before the tune was installed.

I know its not everyone's prefered method for getting more power out of their b58 but I'm running a jb4 on map 2.

Mods:
Cts turbo intake
vrsf catless dp with o2 spacer on the rear o2 sensor
Xhp trans tune
NGK spark plugs gapped to .022

I was finally able to log in 4th gear but I ran out of road towards the end of log.
Will be going to an MHD BEF in the future to control my fuel trims better but can anyone explain what a high fuel trim means because Im at 49 out of 50 for most of run.
