Ran another log today to see if it looks better than my previous one. Thanks.

Good Morning everyone
I've had what seems like infinite troubles with my car lately. I removed and cleaned my VANOS last night and did a few pulls.

I was running MHD V8 Beta maps Stage 2+ 91

2010 335i
FBO
91 Fuel (California)
Brand new turbos, HPFP, Fuel it Stage 2 LPFP, Waterpump, thermostat, coolant sensor; injectors (index 12), NGK plugs, coils, pcv valve,

Any guidance on this log would be appreciated.

https://datazap.me/u/amgklr/3rd-gear...og=0&data=3-12

Ps: this was pulled last night; since then I've switched back to V7 Stage 2+ 91 map

Good, nice multi gear pull.
Ambient Air 14.5 (up .1 from yesterday - more what normal should be - ) since you're in DFW sounds like the cold front stabilized
Full throttle for about 7secs. Coolant temp stable. IAT a 32 degree increase. That's pushing the limit.

Now, about timestamp 167.5, is where things get complicated. It shifts into fourth, your short term trims drop to 0 for a bit, then you go over boost target, and you get throttle closure. Then, after it goes back to making power, you get timing retards.

Im still trying to wrap my brain around this.

I need a drink.
Give me a bit.

Right after the shift you did hit the torque limit. So that is probably what tripped the STFT to go to zero.

the BEST way to solve this is to pay about 450 and get a custom tune. It will give you some margin of headroom on the load target and you wont get as much throttle closure. Someone that knew what they were doing could tune several aspects that would keep you below boost target but still give you some headroom after the shift and would keep you from timing retards.

Well, there is very little time in this log at WFO. I see about 4.5 seconds. And there are very few parameters being logged. Are you sure you are set to defaults?

But, anyway, you're getting almost a 25 degree IAT increase and some corrections really quick. So, can you try some other fuel?

Can you dump some ethanol in there and set all logs to default so we can try get an idea what it would be normally. I might even suggest you drop to an S1+ map and log to see whats going on. This is not too conventional..

I can verify everything's set to default. I don't recall adjusting anything but I'll double check and switch to the Stage 1+ 91 map and relog

As for E85. I don't have a station by my work. It's a little out of the way so for now I won't be able to get a different fuel reading.

Then set these log parameters manually.
Time, Ambient Air, ACC pos %, boost mean, boost target, coolant temp, Cyl1-6 TIMING CORRECTION, gear, IAT, LAMBDA #1 and#2, Load Actual and Load REQ, STFT%1 and 2, throttle position %, torque limit act, and WGdc% for bank1 at least..

that is a good start.

Hello Everyone,

I've been having some issues with random timing corrections, and I can't seem to find what the issue is. I've just taken 4 logs and I was hoping someone would be willing to take a look at my logs and give me some insight on if they're showing anything wrong.

Logs.
- 1st Pull 3rd to 4th gear
https://datazap.me/u/meatwad63/2007-...og=0&data=3-23

-2nd Pull 3rd to 4th again on return trip
https://datazap.me/u/meatwad63/2007-...og=0&data=3-23

-3rd Pull 4th gear only(Noticible surge in pull at time 51.53)
https://datazap.me/u/meatwad63/2007-...og=0&data=3-23

-Last log set on cruise on the way home has timing corrections randomly
https://datazap.me/u/meatwad63/2007-...og=0&data=3-23

Mods - VRSF 5" Stepped intercooler - VRSF Lower Charge Pipe - VRSF Upper Charge Pipe /w TurboSmart RacePort BOV - VRSF Catless Downpipes - VRSF Dual Cone Intakes - MHD Stage 2+ V8 93oct

Thank you so much to anyone who takes their time and checks these out for me.

Not an expert but have you done the maintenance for coil packs and spark plugs yet? Some of the timing corrections seem like bad octane to me. Try flashing the 91 octane tune or filling with 1-2 gallons of e85 and see if they go away.

that is a good start.

I tried to switch to the Stage 1 or Stage 1+ map but I never purchased them (only stage 2 and the E85 maps) So I switched to the V7 Stage 2 maps instead.

I did a total of two logs, see below

PS: I set the monitoring to default before everything so hopefully that's what you were asking for

Not looking good on AFRs. Short term trims are maxed at trying to add fuel but still way lean. Retards are not very good but I would not worry about them until you get AFR issues sorted out. I would reset LAMBDA adapts

Went to rest LAMBDA adaptations and apparently it's an additional add on for the MHD package....

I guess I have to buy the backend flash module before I can reset adaptations?

Also, my car is catless and I don't have a DP fix installed (I'm assuming the MHD module is automatically fixing that) but could that have something to do with it?

I replace my spark plugs about every 7-9k miles, however, I have yet to change coil packs. Hoping to get the bimmerlife/precision raceworks coils soon.

Even immediately after my spark plug replacement I was still seeing timing corrections, even on stage 1 tunes. Also on e25-e40 tunes. I will try adding some ethanol to my 93 tune when I fill again, and take some logs.

So how did you have mhd installed?

I purchased the flash module, monitor package and the Stage 2 maps and the E85 maps but when I went to reset the LAMBDA it said I needed to have the backend flash module installed which is to add custom maps I suppose which is an additional $50 lol

Back end flash is for JB4 type installs.

I have a custom tune and all I bought was the
INSTALLER/Fasher
S1 map (initially)
And monitor.

That's weird. I'll restart the tablet and see if that changes anything

Will reset both lambda adaptations and switch to map 0 and try to get a log.

Heres a few logs of MHD V7.1 one maps. To my inexperienced eyes they seem better than the V8 betas logs that i posted previously. Any insight is good.

Eh, not bad for 91. Timing is ok, boost is kinda light at first but stays solid in the upper range for that map.
Kinda strange you were getting long term trims up about 3 secs into WFO. That and the fact that your short term trims are pretty high makes me think it hasn't had enough adapt time yet.

I would reset LAMDBA adapts, drive it a tank or so. Wait for good air (just when a cold front passes), make a pull in 3rd and a bit of 4th, and note all ambient air aspects in your datazap log (humidity and temp). I get the impression you are near sea level (cali?) so most of that stuff wont be too much different.

The second screen shot with the big PURPLE spike is when your short term trim went over 28.. which is pretty strange.. That hopefully wont be present in the next log.

OK so I reset the LAMBDA adaptations and then pulled the following logs:

First: Stage 2 (Same as yesterday, only difference was resetting adaptations)
https://datazap.me/u/amgklr/mhd-stag...24-25-26-27-28

Second: Stage 0 (Stock Map)
https://datazap.me/u/amgklr/mhd-stag...24-25-26-27-28

Third: Stage 0 (Stock Map; additional pull)
https://datazap.me/u/amgklr/mhd-stag...24-25-26-27-28


Come to find out; I live in California and I've been using the regular 91 octane maps instead of the 91ACN maps. I havent had a chance to switch to 91 ACN, but perhaps that has something to do with it.

I actually reset lambda right before this current tank because i had a fuel mixture error on the v8 beta maps. I had pretty high long term trims that we suspect was my rear o2 sensors which im going to check this weekend.
Also what is WFO?

I am at sea level, SoCal. Sadly were having a mini heat wave of about 88 this weekend which makes terrible sense since it was decent cold front this past weekend.

Mind taking a look at the v8 log which had some pretty interesting stats.
