Anyway you could email the person that sent you the file and ask them to send them to me? My email is danielpajak@hotmail.com

i have run e30 maps as well in the past, the stutter was much worse when running these maps which leads me to believe the culprit is the lpfp when on 93 and e30 blend.

Did you change the lpfp yet? We are waiting to hear! Hopefully it took care of your issue if you did.

I just saw on the FB page that they released all the ACN maps and they are now under the OTS tab on the website (just confirmed). If you have the map pack you can move it over to "My Maps" and flash.

I just went into the app and checked and all the acn beta maps are there now! Thank you for your help I’m about to flash over!!

Can anyone tell me how idle timing should work? Mine is all over the place and I'm not sure if this is normal.

my hesitation problem was my clutch slipping. fueling is great.

Thoughts? Thinking about switching to the standard 91 octane tune and seeing what happens as this gas appears to be better (consistent timing advance) compared to the chevron or shell 92 gas up top.

Anyone have an input on this log?

Running NGK gapped to 0.023.

Based on my not so thorough analysis:

Timing is not great, two instances of knock detected.

HPFP keeping up, boost hitting targets. Ambient was about 75F so IATs look good?

Guessing it's an octane issue? Chevron 92 from WA state.

Welcome to the gas quality struggle. You should run ACN map or 1/3 can of Boostane Professional in each tank.

Do a proper log first.

8AT you need to do a 2nd to 4th gear pull, starting from 2000rpm to 6500rpm, if you don't have space, do a 4th gear pull, same rpms.

6MT, you do a 3rd gear pull, same rpm.

[JaredG_F30]

Costco gas seems to be a bit better quality but if I were you I would run the 91 ACN map and call it a day. With the gas you have you aren't going to see great timing advance.

Even with the knock and overboosting events on the ACN map?

Considering ordering some boostane and just deal with the orange deposits over all the plugs and o2 sensors that concerns me less than knocking and damaging the motor.

[JaredG_F30]

Have you tried stage 1?

Seems like it was the ACN map causing overboost or me resetting the adaptations that fixed it.

Switched to the standard 91 stage 2 map and looks better all around.

Thanks for the help!

When should one reset adaptations? I ran the Stage 2H map for about a day (so amazing!) and now flashed back to regular Stage 2. Should I reset adaptations? Car runs fine, just wondering...

[Bimmer Nerd]

Hey Fellas,

Do you mind taking a look at my log below and give me some feedback to solve my stuttering issue?

I was running E30 mix/tune for little over a year. The car ran perfectly with no issues.
Approximately 2 weeks ago I switched from E30 to CA91 tune + transmission update and the car started stuttering almost immediately ~50% + throttle. I thought there might have been some Ethanol left in the gas tank/fuel lines so I drove it carefully under 3K RPM and went through the whole tank, nothing changed.
After 2 full tanks of CA91, I switched back to E30 mix/tune hoping to fix the problem as it was functioning correctly before the change. Unfortunately, the car is still stuttering and I couldn't get a straight answer from PTF guys.

From reading the latest round of replies on here, sounds like trialmountain and I might be experiancing the same issues?

I've reset all adaptaions, ECU, went to a different gas station etc... no help.

Can anyone help me out? Spark plugs have less than 20K miles on them. Coils are undetermined....but not sure if its a hardware issue as the car was running perfectly fine before the tune changes.

Thank you in advance!

Run on 8/20/19 (after reset, back to e30 map...etc)

Try the ACN 91 Map (as it is made for California 91 octane). You're getting throttle closure down to 35% through your initial pull. I would guess this is because you don't have adequate octane with pure CA 91 to support the tune. Based on the how much timing it's pulling and knock events I would not try to run this tune again with that fuel.

Your 8/20 logs to my rookie eyes doesn't make it seem like it should be stuttering. No major variations through each pull, consistent timing, no HPFP crashing (difference between target-actual) no throttle closure.

I'll let someone with more experience chime in though. That said, your 91 log appears a ton worse than mine so I don't know if we can correlate this as the same issue.

[Pray for Mojo]

I'd try and flash back to the map version it ran well on to eliminate the possibility its software. If that doesn't work, you could try cleaning the MAF sensor with CRC Sensorkleen and see if that helps. If you're using a non-oem air filter there might be some oil on the MAF.

Going to try the ACN map tonight. Will report back with any changes.

I tried the same E30 flash, but unfortunately, the original file (v1) was already updated and removed from the OTS maps to V7.2. I will try the ACN map tonight and maybe put 100 octane fuel in there to get rid of the possibility that its an octane issue.

Hi everyone,

Please let me know your thoughts on the updated log.

Still, there's a little stuttering present. I'm starting to think the clutch might be slipping from 1 year of E30 mix. I'll take it to an Indy shop if you guys can't find anything from the logs.

ACN91 tune.
Half a tank of CA91 and 2 gallons of 101 Octane. So octane should not be an issue according to my calculations.

[JaredG_F30]

Are you PWG or EWG?

All kinds of wacky stuff going on in that log

1. First thing that stands out is your IATs are extremely high. 155F IAT is significant and the DME will pull timing. Ambient temp isn't logged so I'm not sure how hot it was outside but if it's not over 100F outside then you should consider a better FMIC

2. You start over boosting at 3197 RPM and hit up to 19.9PSI with a boost target of 15.8PSI at 4147RPM at which you have a throttle closure. Boost starts to settle down then undershoots and by the time you hit 5802RPM you are at 12.1PSI with a 15.8PSI target. Not sure if that is a PWG thing

3. Timing across all cylinders is pretty consistent so that is good

Still not great, it's pulling timing and you're overboosting to 20psi instead of the target 15. ACN map overboosted for me as well. Again i'm no expert just taking what info I've read in the last month since tuning with BM3.

Are you PWG or EWG?

Why not just stick with the E30 if it works? Could be the clutch slipping, but you'd probably see the revs go up faster than normal if that's the case?
