Anyone want to take a look at my logs for fun? E30 Stage 2 map. Filled it with 15 miles left to empty. Added 5 gallons of pump gas and 2 gallons of e85. Thanks

Super clean.

Awesome!! Thanks! IAT's super hot but its like 105 outside so yeah. I miss the cooler days. It pulled so hard even on the stage 1 map during the winter lol.

Log one pull in 4th gear too, my logs looked fine in 3rd gear but the timing was bad in 4th. It was due to bad fuel. Wouldn't have known if I hadn't logged in 4th.

What you said is correct. Timing isnt great. Did you check the gap of the plugs before you put them in? Its not the worst timing ive ever seen, but cyl 3 goes negative in one of the pulls, and in a different pull, you get a knock during WOT which is not good either. It might be worth trying the 91 map to see if timing is better, incase your 93 quality isnt great. You could also try adding some ethanol to boost octane. IATs are reasonably high but not high enough to cause significant timing issues, and yours are more isolated to specific cylinders and not across the board.

The other thing is that your MAF is pretty erratic for being on stock intake, but not much you can do about that. You are maxxing it at 41.4 which is pretty good airflow for stage 1.

Yeah, timing looks pretty good. I would also recommend logging 4th if you are 8AT as that is the 'proper' logging gear to get representative data.

The other thing i would note is that your WGDC is really high after about 6k rpm. Like nearly 100%. I wouldnt rev past 6k anyways, its pointless, especially with stock turbo. Shift at or before 6k.

here goes another pull still getting some misfires but this is a wot with "protunning freak" doing idk what. the car basically acted the same


and here goes another one part throttle

Thank you for the input! All gaps measured at .030. I'm gonna open a ticket with PFT and re run logs on the 91 map. I completely missed the knock! Thank you again!

Timing is unbelievably bad in the 2nd log. Like negative across all cylinders... Something definitely wrong, or at least the DME thinks there is something wrong, and is pulling massive timing.

Did you try resetting adaptations?

Did you try stage 1?

Did you try a map other than ACN like 91 octane?

My rule of thumb is if the timing is 5+ consistently, it's good.

Negative is bad, not everyone has access to E85 or good quality 93 oct, but quite honestly, your throttle angle stays at 100% the entire run, and the one cylinder that had a negative timing pull will probably go away as it was just adapting to the fuel. As you can see in the next 2 logs.

knock at low rpm at high gear is normal, including low timing as you would never start WOT at such a low rpm for a high gear. The knock at near 6k rpm however may have been a glitch or temps rising near the 100F mark as timing starts being pulled between 103-105F.

His timing is fine as long as it's above 5+ If you're expecting 8-10+, it's fairly rare unless gas quality is amazing, or people are running E85. There's alot of expectations that the good timing as to be double digits, but in real life scenario, having 5+ to 7+ is really good without meth or E85.

Best way to tell if it's a bad log, is if throttle angle closes in the run, and doesn't stay at 100% (Usually a sign of either overboost, or timing pull.)

I am fully aware that knock is normal for non WOT driving, especially during cruise when the DME is trying to optimize fuel economy and emissions. However, his knock was at 5866 RPM during WOT and full boost. So yeah, not when you want to see knock. I didnt say it was catastrophic or anything, just pointed it out. Not an issue if its rare, more so just flagging to keep an eye on future logs.

Regarding timing, i just said it "wasnt great" - i didnt say it was bad or he had an issue, merely made an observation on what i saw in the log. Personally, i would be quite disappointed if my timing was 3 or more degrees below target across all cylinders, but different people have difference expectations. Yes, some amount of timing corrections is totally normal and i always say you will drive yourself crazy chasing perfect timing (been there, done that), so it's up to him if he wants to just continue using this map or try a lower octane one to see how it looks. Its very possible to have more consistent power on a lower octane map if your higher octane map is always pulling timing (generally speaking, not necessarily saying this is a example of that situation). His timing targets are actually relatively high, but that's because he is on stage 1 map and timing targets decrease when boost increases. On stage 2 93 map i am pretty sure the timing targets peak at 9 at a little over 6k rpm. I have seen ozymandias435 collect numerous logs on 93 octane map with 93 pump gas in FL that have literally perfect timing in all of them. So yeah, it really depends on gas quality in your area and how much correction you are willing to accept before trying a lower octane map. For stage 2, its really the ethanol (or race gas) maps that will target over 10 degrees up top at full boost. I see up to 12.5 degree on MHD stage 2+ E20 map, for example.

In terms of throttle closure, BM3 is very lax with throttle intervention. You almost never see a throttle closure unless something bad happens. So i suppose you can use that as a high level check to see if the DME really thought something was wrong, but the tune is not nearly as sensitive as MHD when it comes to throttle closure intervention for overboost or other general protection. Hell, the BM3 tunes even intentionally overboost (at least stage 2) at the beginning of the pull, and there is no throttle closure.

yes i did i tried stage 1 acn and it did it on that one too

it just doesnt do it on stock map

Noted. I am used to logging a 6mt car. I will do 4th gear next time. What does it mean if the wastegate is at 100%? It just means its wide open right? Is it bad? I told PTF to add a feature in the tunes so we can limit rpm, that way it would automatically shift at ~6100.

Oh, if you are 6MT then 3rd gear is fine. I mean, you can still get a 4th gear log if you can safely do so - the long pulls with a lot of load collect great data. But no need to if you can get a full 4th gear pull.

WGDC 100% means the WG is fully closed and the turbo is at 100% duty cycle - i.e., it is literally spinning/working as hard as it possibly can to maintain boost. Not something that is sustainable long term and it pushes the turbo way out of its efficiency zone. Its going to generate a lot of heat and potentially accelerate wear if you push it like that for a long time. It basically means you are pushing the turbo to its limit.

Note that WGDC at 100% at the beginning of a pull is normal (sport + in particular does this so that the throttle response is better), but it should drop once you reach boost target, and then typically slowly rises back up with RPM. After installing my inlet and MPPK airbox mod, my WGDC is now in the 82-89% range from 2500-6500 rpm with 16.7psi peak on MHD stage 2+ E20 map. I see alot of BM3 tunes pushing it to mid 90s, but yeah, i just wouldnt want to run something that pushes it to 100% all the time.

Here's an example of one of my logs so you can see what i mean: https://datazap.me/u/thejeremyman9/2...data=4-5-21-34

Should have specified I have a 6mt single turbo g37. I am used to logging that in 3rd mostly. But okay I understand it now. Really pushing that stock turbo on e30. I don't plan to run e30 all the time. Decided to try it out because why not. This is my daily so I usually just have it on Stage 0 (oem m2 map) or stage 1.

[codestar]

Quick question regarding the st2 e30 map:

Would it be safe to (carefully) drive on just 94 to get to the station that has e85 to finish the fill, or should I flash back to the 93 map for the 5min drive and then reflash the e30?

I'm just curious how others do it when your reg gas and e85 are at different locations. I would prefer not to buy a jerry can if I don't have to

Yes, should be fine, just don't go into boost. The E map is essentially going to supply more fuel and target higher timing. If any corrections are needed the DME will do it. But again, key thing is to not go into boost or high load because you dont want any knock under such a condition.

excellent, thanks for the quick response!

When I made my first fill and moved my car away from the pump to a parking space to switch to the e30 map, the head unit had thrown a fueling problem on the screen so I wasn't sure. After I flashed and cleared the codes it was fine though

Hey guys, so after my boost leak when I first installed everything, car has been running great. Absolutely zero issues.

I’m the type of guy that wants to make sure everything is running right, so I decided to do a log. I get this: https://www.bootmod3.net/log?id=5f1b...0b4377a7aa8254

Uhhh, is something majorly wrong? Seems like there’s something going on. I also have a showdown code 1A2108.

[Moto-XXX]

Has anyone tested the VMAX removal?
When I tested the top speed of my car I could not reach a higher speed than before, 260kph on the speedometer and 236kph according to Waze.

So what is your concern if you think something is going on?

The boost control is a little strange and you have a clear deviation from target. If you are PWG the drop off up top could be normal but you also fall below target quite a bit earlier on as well.

Timing is also pretty bad. One cylinder even goes negative and there are alot of corrections.

Fuel trims are also pretty high at >10% fuel added throughout the pull. Not sure if you are running an intake but MAF looks a bit erratic.

Are you sure you werent drag limited? Are you on stock tune?

I did 160 mph speedo indicated when my car was bone stock (Msport though, so i believe no speed limiter).

I did 171 mph GPS indicated with stage 2+ 91 on MHD, which the vmax box checked, if that even made a difference.
