This log is from the OEM MPPSK tune included with my bootmod3 license taken today. Its quite warm, but the corrections seem less extreme
https://www.bootmod3.net/log?id=6119...90c6768b3aff0f

Looking at the timing corrections has me a little concerned. I rolled back to the OEM MPPSK since I was a little annoyed with the stage 1 tunes surging on part throttle in day to day use. I just changed back to the OTS Stage 1 to see if a different surging goes away from the stock tune (seems to be somewhat normal behavior on b58 engines according to some others saying similar things in this forum https://f30.bimmerpost.com/forums/sh....php?t=1541584) Ive tried finding better fuel here is CA but 91 from shell seems to be the best I can fine that is close to me. Next time I find myself near 100 octane I plan to add a little and trying the log again.

Do either of these maps look safe to run for the long haul?

Thanks for looking!

You sure that second log is OEM? I see you hit 19.3 PSI on the stock turbo.

Could someone look at this data log I did Saturday night? Seemed to me that there was a bit of a drop in rail pressure near the top end, but I don't know if its enough to be concerning. Also slight timing corrections, but once again not sure if they are very substantial. I don't know too much of what I'm looking at but want to make sure everything is fine since I'm about to put in a TU pump. Thanks

After some reading, I believe the answer to this is due to the lower pressure in the cylinder we need more timing.

How much timing you can run is a dependent on of a lot of things including octane, combustion temperature, boost levels, etc. Usually it's a sensitivie balance, because boost that's too high will create extra heat and reduce how much timing you can add (unless you have more octane to compensate for it). Ultimately the stock tune's boost levels are so low that high timing can be achieved.

a smaller turbo wil put more heat into the air for the same amount of air at a certain pressure , compared to a bigger one . thats why increasing the boost beyond a point where iats skyrocket is useless . You need to upgrade your turbo .

Hi Kevin and all,
I'm seeing corrections on cy2 as high as -5. Is this due to the lower LTFT (.94)?

Sometimes, shortly after powering up, I would feel the car slightly shake (like it's trying to clear its throat) and trying to cut power on ~75% throttle. And when I get on the highway to do WOT, it disappears again.

I'm wanting some feedback on these two logs. I'm still not following how to make sense of these too well. I see a lot of corrections as I have been since I've been logging (can't seem to find a correction free gas here in central IL - even adding 1 to 1 1/2 gallons of e85 to top off a full tank). I'm wanting a tune that I can trust and I'm not sure which one of these I can stick with long term.

One thing that happened on the stage 2 map that makes me a little nervous - after the run - I smelled what seemed to be a burning electronics stench. No codes according to MHD. When I arrived home - I popped the hood and figured out that it's the sensor that is plugged into the charge pipe - the smell was pretty strong. I believe it's the charge-air pressure sensor. Again - no codes thrown or anything. I guess I should probably replace that sensor? I'm not very keen on how those wear. That smell has always told me of electrical equipment burn.

ETA: the sensor could have been the IAT sensor. hmmm. or maybe the boost pressure sensor? i'll take a pic and upload

ETA x 2: it's definitely the MAP sensor that smells like burnt electronics

ETA x 3: ok removed the MAP sensor - that doesn't stink like burnt electronics. I do believe the smell is coming from the valvetronic actuator :-|. What are the signs of those going bad? I see those aren't cheap.

I'd look for an ebay part or getbmwparts after you've confirmed it's a problem. Could be plastic burn/melting?

I drove the car today and it seems to be ok. No odd noises, no CEL's. The smell is starting to go away. I wonder if there is a way to test the eccentric shaft as well as the valvetronic motor to determine if they are working properly or about to fail. Driving around it seems to be working properly but I'd like to know if the part(s) are going bad.

Following up on my ask. One thing I'm noticing in the logs is that when the torque at the clutch hits 400 ft lbs it sort of flattens out a bit. I wonder if I'm hitting a torque limit for 4th gear? Been reading that I believe the limit is roughly 400 ft lbs. I do have XHP installed but only stage 1 - which I don't believe removes the torque limit for 4th gear?

Was hoping for a little more power on the dyno with the VTT GC ... made 508 WHP / ~ 550 TQ on Pump 93 with WMI on a Cary Jordan custom tune. We ran about 25 PSI but only got up to 11.5 degrees of timing - thoughts on the log and dyno chart????

Hi guys

I have a m240i and recently installed meth
I have a decat
.022 Gapped plugs
Tu pump

Im using 99 ron uk vpower + meth . Running MHD stage 2 HPFP 102RON
After speaking to MHD they said i can run the 102 ron map with meth. I gave it a go and the logs are below. Im not the best with logs. How do they look to you guys?

Also do you think id have further gains if i got a custom meth+pump map?

4th gear meth:

Ouch. A bit steep. I tried selling my full map pack for $350 and no biters. Plus wrong thread to post for sale.

Hi

What is that 1048576 torque limiter. I get a bunch in this log. Is it because of these torque limit settings? I feel the car is being hold back...

Timing looks good, close to boost target throughout the rev range too. Your WGDC, it's touching 93/94 at the top end of the rev range, which is quite high and indictaes your turbo being worked pretty hard, but would explain why you're achieving 20psi+ still near 7000rpm. BM3 generally taper at the top end down to 18/19 psi and WGDC topping out at 89/90.

No right or wrong, your stressing your turbo a bit more, but going faster as a result. Pay to play and all that!
