Will do a log in Map0 before flashing map2 to see if everything is fine before tuning. Does that make sense?

My linear throttle works great, and no plans of ever going back to stock throttle map. Regarding the other con, I will randomly at times get the short throttle burst when applying little throttle. It happens every now and then, for instance when I am coming to a stop and doing a Cali roll.. Car won't take and then it kicks in really fast and launches forward.

Pros - I've never done the cold start noise reduction, and from reading people having issues with it I am skeptical on trying it. Also, never tried raising the min rpms, what exactly does that help with?

I am running the Stage 2 Plus MHD map. However, my car still raises the rpms up to like 1000 when I come to a stop with the AC on, and then goes back down. I noticed it in the beginning, but not much of a big deal anymore. Doesn't ever happen when the AC is off.

Hm, might give it another try then and reset the throttle also.

I read that too, but the cold start was way too loud for me with PE + DP, so I gave it a shot and what can I say, working as intended

My last car was a 323ti and it had that awesome smooth idle. I know you cant get that in todays BMWs, but at 850rpm idle its ok now. Always thought that 650rpm is much too low and the car was rather rough and shaky. Well, that is a thing of the past now and I couldnt care less about the additional 0,0001l gas consumption

That link should work... Yes, car started and has been driving fine so far. I'm thinking it's the battery from what I'm reading, but the charge was fine when I hooked up the battery charger... And the code and issue in the video don't add up to me.
So its fine now since going back? Keep us updated

Raising the rpm is mainly for smfw guys to help with the chatter but I agree with above the idle does feel smoother

Tried E30 map today with E30 caluclated by http://www.wallaceracing.com/ethanol-mix-calc.php.

I had some real bad stutters up top. You can see it corrects timing BAD up top right after my rail pressure drops to ~1750. I didn't think it mattered till 1500?

Anyone have any advice? I was running just fine on the 91 Tune. I'd get minor timing corrections, but nothing like this.

You need a aftermarket intercooler or meth in phoenix. Your car is pulling the power probably because IAT is high. Stock IC will suck even on stock tune there in summer. I don't think E30 is enough to be able to "ignore" IAT.

Ugh, I know.

I'm running around 120-140 IAT.

Why are you trying to do a pull in 6th gear lol? Down shift... That's your first problem. Second seems to be that your rail pressure is dipping and afr is leaning out. Either too much ethanol was added or the tune is a bit too agressive for your car/fuel pump.

Can someone please look at this log for me. I have been having issues stalling out coasting in neutral on cold starts, or during reverse to 1st changes on cold starts, as well as fluctuating idle rpms on cold start. I don't know much about timing corrections, but from what I've researched, I don't think this looks great. I'm seeing much bigger corrections on the # 4 & 6 cylinder, some on #3 & 5, and 1 & 2 looks fine... I'm not expert, just trying to narrow this down, so any help is appreciated.

could be a vac leak like said. Notice it was pretty rich before building boos.t i'd reset fuel adaptations. And see if it improves. if not. may be a vac leak.

Sounds good. I'll try to get it done before I head out to work tonight and take some logs. How is the timing looking on those logs as of now?

*edit* Attached is the new log. I reset adaptions and timing does look much better overall from what I understand... If something is still not looking good to you guys, please let me know. Also, if this something bad enough that I should stop driving my car immediately, please let me know, lol.

I wasn't trying to do a pull, just putting the car under load to see how it would respond, and logging was on for that.

I'll try a proper pull later, although 1-3rd up to 6k is pulling REALLY strong right now.

What's a low rail pressure reading?

Under 1800psi or so? Depends on what's being targeted but that's what I'd consider to be low, personally. I'd like to see my own over 2k psi even though I've had it as low as 1300psi without issue. Really depends on other tunung factors that also affect cylinder filling.

Can someone look at these logs for me and tell me how they look please? I was told I was running rich before boost, and also had some timing corrections, but I've reset adaptions and hoping things look better now. I think timing looks better now, but a confirmation would be nice, and I have no idea how to tell if I'm running rich or not.

https://datazap.me/u/csween86/log-15...og=0&data=3-14

Also, I need a new battery. If I get the same type of battery, can I just use the reset battery adaptions feature on mhd, or do I still need to code it? Thanks.

Well your lambda does dip pretty low right when you hit boost. Also, the boost spike when you let off could be a DV issue. Other than that the tune looks good and your IAT looks great. The timing corrections are very minor and no worry.

Sounds good, thanks for looking. I've talked to Justin before and I think I remember him saying boost spike is normal when letting off after wot or between up-shifts... With the lambda dipping low, what issues do I have to worry about with that? Is that likely a failing o2 sensor?

Here are a couple logs. Car has gutted downpipe and charge pipe, running ~E30 mixed from E10 93 and E85 on latest STABLE mhd release, 1.24 with v1 maps.

First log is from racing a F80 M3, at first dead even then I started pulling slowly near the end. Now timing corrections look great but what's with the ridiculously low advance? I am worried about high EGT with this timing. You can see it goes from 6* at 5500 to 3.5* a couple gears later, both at full load with supposedly no corrections. What's the deal?

https://datazap.me/u/germaniumcars/l...og=0&data=4-16

Second log is a brief pull on the E30 tune. Obviously the car is not happy. Now, I don't have an intercooler but these are brief pulls and the IAT does not get that high. Any thoughts? Surely the addition of an intercooler alone to the current setup is not enough to run this with safe timing corrections.

Update to the guys following on the cold start stalling and fluctuating rpms issue. My battery went completely flat a couple days ago. I just changed it today. I think that was the reason my instrument cluster was wigging out and car failing to start at times. Not sure if that's what was causing the rpm fluctuation and cold start stalls, but I think it is though. I'll give it a week and let you know how I make out. I did flash back to the beta version since I had left that initially as a precaution, but doesn't seem to be the culprit at all.

I recently did the MHD BEF w/ JB4 and am getting the cold start issues. Low rpms and any throttle and the engine will sputter/drop rpms. Not sure the cause.

Your IATs are super high. The tune is set to reduce timing target as IATS skyrocket. hell, on the E30 tune, your IATs get up to 170 degrees. You're running a tune made for intercooler and downpipes. Tune is doing its job by removing timing to keep the engine safe. Mod recommendations are there from a reason. use them
