Yeah i noticed the torque limiter being reached!

Thanks for the info and hoping this torque limiter will be solved soon!!! Ive had this issue from the beginning but it seems like its getting better from my first few logs.

Yeah I know the struggle but I'm confident that MHD will find a solution. I'm really curious why this is even happening at all! And why only a few cars are affected??

i was under the impression it was related to early build PWG DMEs, but i now see EWG cars effected as well...? hmmm

Power was not linear at all, but hit you all at once, and my shifts were really rough for some reason. Finally, I was running very lean, although that is common with JB4 users. But my car is running much better now, power delivery is stock and strong; I was hitting 17 psi on a quick run I did yesterday.

I'd suggest you scroll back a page or two to see the big discussion on JB4 that just happened on this thread.
Thanks for the reply, you've described my experience with the JB4 BEF combo exactly. I love having the features of the JB4 but right now it's not quite fully fledged, and my first track event is less than a month from today. I'm not comfortable running that tune on track just yet. That said, Terry has been very helpful with BEF revisions and his communication is damn near instant through email. I'll probably continue to fine tune the BEF with him during the off season.

Also, 17psi is impressive, but I'm PWG. Curious to see how the PWG stage 2+ compares to EWG. Might even grab the ethanol map for track events, assuming my intercooler can keep up.

I have timing corrections as well in my logs running on stage 1 stock, 91 octane. Car is only 23k miles so I don't think it's plugs/coils.

Is this common due to low octane?

I'm using 93 oct stage 1 flash so it's not a octane issue

yep...that's why splashing in some e85 is so helpful to those with low octane...

i can run the stg2+ 93 map with 0 zero timing corrections on e20mix...super punchy low/mid range, great spool, very smooth...don't necessary need e30 maps to benefit from e85...

I'm 6mt, thanks for your help!!
Aren't the N20 plug colder plugs than the N55 ones? I thought a lot of tuned guys were being recommended to run these plugs..? And I hope you mean 0.025" but why that gap?

I don't know if advising people to arbitrarily splash in some E85 is a sound idea. Although ethanol does raise the octane level, it is also less energy-dense and more of it is needed, so it's not just a difference in octane level. Unless they know how to calculate the ethanol concentration and are ok with possibly deviating from the map's intended targets, they should probably just stick with the octane rating for the map they chose. What works for you may not for others and they also may not have the same level of knowledge that you might have.

thanks for all the self righteous concern but this e85 stuff is kinda old news....

wait, you're right i should retract because many in this forum apparently can't search/google "e85 n55 pwg ewg" and/or perform basic algebra ...

400 at the wheels? with pwg? sir, are you ok? 400 at the wheels converts to ~460hp at the crank considering 15% of transmission loss. while this car has 306hp stock _at_the_crank_ (~300 in reality), so do you really think that you added 154hp to your car with stock pwg turbo just adding some ethanol and tune )) really? to make something around 450hp _at_the_crank_ from 3 litres you need at least 1.2-1.25 bar at high rpms (17-18psi at 6000-6500rpm) not 0.7-0.8 bar (10-11psi) you have now. make a video of your 100-200km/h (60-130mph) acceleration and I will tell you how much approx hp you have. If you have 400whp (460 crank hp) you should do 100-200km/h in 8seconds easily (stock m4 does it in ~8.7 seconds), let me guess how much it is now? 11-12 seconds, right?

The plugs were on my previous car and had hesitations with jb4 and I tried different gap and forgot to re-gap them when I did the installation on my 335.

I will put back my old bosh spark plugs today (gapped at 0.032 from the factory ).

What type of plugs to use seems to come up a lot, from what I've gathered the stock plugs work just fine unless there is some special circumstances, very highly tuned for example.


What octane fuel are you using? If you're using 91 absolutely try supplementing with e85. www.*************/howie85 for my noobies guide on using e85 to supplement octane.

Still responding to posts like a douche I see. Don't take it so hard, it's not a dick.

It wasn't meant to be self-righteous, but more of an advisory to those who may blindly throw in E85 because they read on the forums from a stranger that it'll magically solve their problems, lol. It's a valid concern to have considering the type of posts that are constantly being posted.

I came from stock turbo PWG and I can tell you software won't fix hardware problem. The turbo is so tiny no matter how much power you have, you will still lose vs a EWG top end, even stock EWG.

Its the worst turbo BMW can put in the f series.

E85 mix won't solve anything, changing the turbo will.

Your link is blocked. what "solid" tune will do? will it increase compressor diameter or turbine flow? I dont care about peak psi, its useful for gearbox breaking and loosing traction only, 24psi at 3000rpm is useless. 16psi at redline (7000rpm) with stock pwg turbo? sorry, I think its PS2 or maybe PS1 territory. If you still cannot believe that stock pwg turbo is crap, add jb4 to your existing flash tune, jb4 will completely close wastegate letting turbo make boost as much as it can (if you believe that current flash tune not enough pushing turbo) and make 100-200km/h run. post your video here. We will watch and laugh how "460hp car" does 100-200 in 11-12 seconds, that's it. For power you need boost. And healthy ignition timing. Period. I'm running 1.05-1.1 bar (15-16psi) @ 6000rpm along with 9-10 ignition timing there and trust me, I'm far away from stock M4 100-200km/h time. M4 does it ~1 second quicker. Yes it's 60kg lighter but in this case it makes more power also. Every stock pwg log I see, stock pwg turbo falls off the cliff after 5000rpm and it's physical hardware limitation, it's very sad that people do not understand that software will not convert their tiny pwg turbo to PS2 ..

Dude get off your high horse, 400 whp on a PWG car has been done before with just a JB4 and an E40 mix of ethanol. No one here is saying PWG is better than EWG, just that you can still make good gains with the PWG setup.

What plugs/gap/mods were you running that were no good and made you go back to the stock plugs/gap?

Wondering as I just flashed bm3 and they recommend the ngk two step colder plugs gapped to 0.02, I bought them but haven't installed yet and am looking for a reason to or not to install them lol
