Actually, I did not read it wrong at all Drew. I very simply read it along with the other comments made by the author and in the context the author intended.

Sorry buddy, it is you that is mistaken. And citing the last couple sentences of the post carried over to this new thread does not change what Sal actually said, the restated, and then said again slowly . . . , lol.

Hes not a nobody, unless you call holding 5 patents in Hydrogen fueled engine technology a nobody. He knows WAY more then you or me.

Different gasoline with different amount of ethanol have different electonic properties associated with them.

You interpreted it one way, myself another, fair enough buddy.

Since no one answered I will. The system works by measuring electrical resistance between between the spark plug electrode of ionized fuel (it ionizes once it is burnt). As you said all this data is compared to data that is tabulated using very complex algorithms. I understand a pre-ignition will cause a very different ionization measurement as the source of the spark is not at the plug which it knows is the norm but which ever part of the combustion chamber caused the ignition.

It is not a very fancy system as you can see but I guess it works for its application. I do not think anyone can tune any changes to this system as the maps are several hundred pages of bytes and I also do not think it can be switched off as the same system is used for several other engine purposes including i.e missfires etc.

He may hold patents in unrelated hydrogen engine technology, but that doesn't make him an expert in the MSS60 ECU.

Lol when the time is right sure. I don't know if the guy wants his name posted. From what I know he also a professor at a university.

It's not my right to post the individuals information but I will if he gives the ok.

Anyways what are your credentials in the topic of the MSS60 tuning?

LOL. I'm not claiming expertise about MSS60; and I'm not even discussing any technical details of how it works. Therefore I don't need to provide any credentials on this subject. You're the one who made the earlier claims that this "world famous tuner" had something to say that would be of major importance. Funny that he's now been downgraded to a professor in a glass bubble at a university.

Who said anything about him being a world famous tuner? He's a professor holding a couple patents and knows alot about this topic. That's it. Why can't you understand that? I'm not posting his name until I get an ok. Geez man.

Glass bubble? Lmao. Come on man you're more mature then this, why are you attacking me?

What are LSB's credentials with dealing with the s65?

Yes, that's what I meant, LBM/Celveland

A few were wondering why low boost would cause knock.

The simple answer is this, either not enough octane or too much timing.

I've never been a fan of dyno tuning, seen too many motors get hurt. And you only leave the dyno to have to re-tune again for the track because there is no load on the motor. Just my .02.....

As most of you know the S65 motor is high-revving, high-compression. There are some great kits out there making good power, but who knows what the longevity will be. The proper way to do it would be to change the pistons or run a thicker copper head gasket to lower the compression.

Huh I didn't delete, if anything I was adding comments. And yes I've been talking to a "world famous very experienced tuner" on this subject as well. From what I'm getting the amount of meth injected matters and unless it's a huge amount it should hold no effect on the knock system. Meth will definitely help prevent detonation though.

What is your experience with high performance engines and tuning? Just a question, since you can question everyone else on anything you want.

I'm also wondering what kind of deposits will be left on the valves as a result of using meth.

Why in the hell are you asking about using methanol?

. . . can't you see there is chest thumping and creditial checking that needs to be done man!

Depends on the amount and if it's straight meth. Meth will evaporate quickly especially if used in a low amount.

I used water/meth for 3 years with zero issues.

I saw your car today at Gintani and was told what is going on.
I must say... WOW!
The sound, the power, the low-ness.
You're car is easily the greatest M3 of all time.
ENJOY!
