Great post, this shows that the JB4 causes nothing more then "mild knocks" so mild that they don't seem to currently damaging N54's..

I can nail you once and kill you, or i can tap you 1000 times and kill you, either way the bat is hitting your head, just like either way the car is knocking because it set up to use a timing curve for a stock car.

If you perfer a bat hitting your head lightly everytime you floor the car then more power to you. Personally I rather not get hit with a bat in the first place.

Or you could tap me 100,000 times, ill be fine, and you will be unable to figure out why

Lets find ways to inform users how to rectify the problem regardless the tune we use.

1. Low octane fuel = Use 93 Octane
2. Incorrect spark advance = ?
3. High cylinder pressure = Use Methanol
4. High intake temperatures = Larger FMIC
5. High backpressure = Catless downpipes

Actually no it doesnt show that at all.

It shows that the knock sensors can only handle MILD cases of knock.

So anything above stock boost would not be Mild. Even Mike himself mentioned that pushing more boost, lowers the safety in which the DME can handle knock.

Again, get a clue.

It's like a teaching a kid how to put the square block, in the square block Hole, but he keeps insisting there is way to get it in the round hole.

I'm not sure where you learned your background on engine tuning and advanced engine tuning, but you have failed the class sir, might I recommend a refresher course?

How many cars have you tuned?

There is no data to support this.

1. or lower timing/boost
2. Lower timing
3. Raise octane or lower boost/timing
4. lower boost or get a fmic/meth
5. lower boost, or free flowings mods.


Theres no one solution to any problem, they are work hand in hand.

you already shot yourself in the foot on this one by demonstrating that a stock car knocks. I'm pretty sure BMW knows how to tune a N54. If you have some proof to the contrary other than "Knock is bad mmkay?" then by all means share it.

I used to follow each of your posts with interest and even made plans to switch to a Cobb, but this whole thread stinks. By your logic there should be at least hundreds of threads with "JBx ruined my motor". I want to believe, but to simply take your word for it against all other evidence puts me into the same group of "know nothings" you and your nutswingers are railing against here.

Please. Enlighten us.

i guess everybody is either slaying dragons, or running the gauntlet.

this has been very uninformative for the most part -- if someone could see the forest for the trees we could get somewhere--

at least thats what i think...

laying out engine operation basics and then overlay the principles used by the tune to enhance performance using safe practice guidelines could resolve this whole thing quickly.

If you want actual information contact the two manufactures independently.

Do the search, or show me your proof, I'm not asking you to reinvent the wheel. For some reason this community believes in hand outs, well I dont.

I did my research, now do yours.

I agree. If he wanted to humiliate someone he should have just started a "yo momma...." thread.

I don't give a shit how much prices are....the market will stabilize it, and that's a laughable argument to begin with.
I think you're confused. This thread shows the timing advance system used by the all the JB tunes over the years, since JB1, safely retards timing under higher boost levels. I think the frustration from your side comes from the fact that the JB method works well, as evidenced by the thousands using it since 2007, yet you can't get your head around why it works and why there are not major engine failures all over the place with it.

A stock care knocks at stock boost in those horrible conditions. What is you point, thats the point of the knock sensor, to save the engine incase the customer finds himself driving in abnormal conditions. If you don't believe a knocking engine is destroying it self, then i simply dont know what to tell you. However I will ask you one question.


Take two bran new 335is, put one in the arizona desert and floor it till it breaks

The the other one and put it upstate new york, and floore it till it breaks.

Which engine will break first, assuming the engines are identical? The only changing conditions is that one is running in conditions that allow the knock sensor to constally drop timing due to knock, and the other is limited by stock timing curve.
