I’m still trying to learn the logs. I think the timing doesn’t look great? Maybe new plugs would help? Should I run the colder/gapped ones I see comments about? I have 40k on the odo.
Thanks!

I had the same issues too. I have a catless AA DP and the Stage2 Ots map in both 91 and 93 were pulling lots of timing. Im in fl so we have 93 gas. I actually flashed back to stock and that helped a bunch. I’ll likely add a little E to see if It’s an octane issue

This was the 93 ots map (Stage 2)

This was the 91 Ots map (stage 2)

This was after I reflash the stock map.

If you haven't changed your plugs at 40K you should, but I don't think that'll help your timing, only less boost and/or better fuel.

If you can't or don't want to use better fuel maybe consider a Stage 1 91 tune?

Hey guys was wondering if someone can look at this log I did. (Previous one I posted was a third gear pull this is a fourth gear)
I had a problem with the wastegate rattling last week. Tried to tighten it and ended up throwing a check engine/drive train malfunction/limp mode. I tried my best to adjust it back to where I thought it was before. When I started it in the morning no check engine was on, drove like a grandma for three days, until I decided to do a little pull before the log and it seemed semi decent. (I made a appointment with a local shop to check out the wastegate on Wednesday) Not sure if it’s all in my head but I think something might be slightly off. (Spark plugs gapped to 0.022)

https://www.bootmod3.net/log?id=5f15...90c66625c37ee6

Thanks guys

*ps. Low end feels fine to me, mid to high seems to fall flat?

Sgm123 · 07-20-2020, 02:58 AM

Do you need to gap plugs for a small amount of e85 then or is stock fine. Only replace them 4K ago so ideally don’t want to touch

Ignition timing advance profile looks really bad. Cat meltdown in 3, 2, 1.. What octane are you using?

Stock gap for plugs is fine up to and including straight E85 with stock turbo

91 octane, in California.
Catless DP.
Any advice? What do y’all think is causing it? Would installing the stock plugs be beneficial?

Eldotbe · 07-20-2020, 04:15 AM

Want to run meth, what’s the best way to go about that. Do I buy the bms meth kit and then buy a JB4 and run their wmi map along side bm3/mhd. Or is it better to get a custom tune to intergrate the wmi, what’s safer and advantages and disadvantages for both?? Thanks

IMS-340C · 07-20-2020, 04:21 AM

Are you now maxing out the stock turbo ? or you you think there's still more in it ?

In cooler weather there is probably a bit more, especially if I further increase ethanol, but not in hotter months here.

N420i · 07-20-2020, 04:35 AM

since timing pulls seem to happen to 90% of us running OTS maps with straight pump gas, and engines don't seem to be blowing up all over the place, should I assume that the OTS maps are safe even with the timing corrections?

Thanks for that reply, this is what I was thinking of trying as well. It's interesting you have different SW (MHD), and still see similar results that I have. I guess it's not a BM3 only issue. I was going to try to run higher octane, or try to find some octane boost to dump in. I haven't looked to see the best way to try it yet.

Do any clean logs exist for B58 motor that do not pull timing? Seems like even stock tunes have some amount of pull. Trying to get a feel for how much timing pull is too much, etc... I've heard the E30 maps work well (I don't have E30 near me), but I wonder what the timing looks like. I'll try to find one.

Engine won't blow because timing WAS corrected and the amount of correction is learned over time. But exhaust valve seals and stems, headers and cats can melt away with time

Do you mean the valves and stems of our engines (in the cylinder head)?
Won't be funny to replace them I guess that's an 2.000 euro job.

Hi OzBMR

Please could you plot the virtual dyno on this log.

https://datazap.me/u/m140bcs/log-159...og=0&data=5-23

440i Gran Coupe RWD - ZF8

Thanks.

Yeah, this is due to excessive ignition retard when most of combustion happens on the exhaust stroke. DME has a failsafe for that - forced load reduction if EGTs are over a certain limit. The question is: had tuner left that limit intact or raised it to allow all of the performance at any cost.

I think there is no way to plot that log correctly - RPM values look glitched somehow.

I've checked the 4 logs I did yesterday and they all have rpm glitches??

IMS-340C · 07-20-2020, 12:43 PM

What fuel are you using ?

Amb. temp. 22C (at night), IAT at the 24PSI 55C

M240IX Pure800, Dorch Stage2...

Well according to BM3, their OTS tunes have left all the factory safety measures in place, but limiting power to 340hp is a safety measure soooooo...

These logs that M140_BCS just posted seem to have pretty f'n impeccable timing...

https://datazap.me/u/m140bcs/log-159...&data=5-23

According to his signature he's only running DP and HPFP on straight 98RON pump gas

Logs were taken with 11ºC ambient temperature and IATs are therefore suitably low at around 22-25ºC though.
