If you think this "expectation" of yours is reasonable then you are smoking the bad crack.

The moment you objected to logs is the moment I started suspecting that the quality of your product is poor. I'm not the only one entertaining doubts now.

The suggestion on your part that your map is "reverse engineerable" from log data is a laughable suggestion, from both an engineering and legal perspective.

Lastly, your objection to logs is a slap in the face to the evo community at large.

You do not have our best interests at heart. Never post here again. Thank you.

Your hypocrisy appears to be boundless.

Rediculing people here who are trying to learn out of a genuine enthusiasm for their car is pretty low. It seems as if you think the plebeians here are nothing but ***** or theives.

The problem with EVERYONE learning is that it is threatening to you. So rather than embrace the sharing of the new found knowledge you rail against it to protect yourself. EVERYONE here can become an expert. EVERYONE here has a right to the opportunity to understand their car and work on it. If EVERYONE here knowing what you know would put you out of business, then YOU should probably be spending less time criticising people on internet forums for thinking they could possibly share your mastery and more time considering how your business might benefit.

The problem is EVERYONE is an "expert" and you have a thread filled of "1-3 counts of knocksum is detonation, add fuel" and "no under 10 counts is fine". Everyone speaks in certainty. Everyone wants to add their .02c as incorrect as they may be, diluting much that could actually be learned by reviewing a log.

I think the only fair way to decide if posting logs is a violation is to identify what exactly is being revealed. Not for selfish reasons but to prove the validity of the concerns of tuners over the posting of evoscan logs.
I agree and this I have already considered. If ign timing was removed I would not care. But it seems that 80% of tuning involves finding a specific knock threshold and timing advance. I am not interested in broadcasting ign timing publically at the current time.

You can spin it however you feel you may want to manipulate the situation to make us look like we are in the wrong. No one has been ridiculed. I pointed out two instances where the log was interpreted incorrectly. If that is riduculing, than no one will ever learn any anything from this thread.

People aren't learning about their car, people are trying to learn about KOEvo's car. If they want to learn about their car, post yours and their logs and I will help you analyze it.

This should solve your problem right? You want to learn about your car, correct? So post your maps and logs and let me help you understand them. I suspect that is not your intention however and you are upset that you are not able to absorb KOEvo's tuned map info for free.

TTP will soon have a solution for the masses. Stay tuned for further info. I think it will solve many ECUFlash users thirst for knowledge. Now testing it under a pilot program.

This is why you are not a moderator and never will be.

Suspect whatever you want. My 146 positive feedback count is enough to tell the intelligent evom non-newbie what kind of experience you would have when dealing with such a vendor. 100% positive.

The suggestion on your part that ignition timing numbers is unimportant and cannot be reassembled in a Ecuflash map tells us all how little you really know about the program and tuning. It's no wonder you are so upset that you no cannot have access to the log to hijack.

My objection to posting vendor ign timing is a slap to no one however if you would like to kick your dog and vent your frustration, feel free. Then think about why you are mad that you do not have access to data that does not belong to you... You might as well complain to the mods that you do not have access to the moderator forums while you are at it.

I think there are plenty of experienced and knowledgeable tuners in this forums that don't make it a profession.

So, if TTP doesn't want to share his maps or logs, that's fine. We can share and learn from our own logs. No big deal. He's just trying to protect his investments and time that he has spent on the dyno tuning, testing, tuning, testing, etc, etc, etc.

But, there are plenty of other people here that have done the same thing. For example, I have used DSMLink for years, which has given me a lot of knowledge on how the stock DSM ECU acts. The creators of DSMLink have taught the community a lot, but most of the knowledge on that board comes from experience anyway. After all, experiencing and learning youself is half the fun, right?

All I am saying is don't sweat it either way. If vendors don't want to share maps or logs, so be it. We'll share our own. Tuning isn't rocket science...it really isn't that difficult. It's just difficult geting past a lot of misconceptions that float around an internet forum like this.

One last thing about the removal of logs....someone said that it was laughable that a map can be reverse engineered from a log. I totally disagree. Show me a few logs from a car and I can reverse engineer the timing map pretty easily.

Thank you for your input, knowledge and understanding. It is clear as day why some are upset that this information has been revoked from display.

It is nice to have some understand the big picture.

LOL True^^

I generally like to observe others in their findings but I've done some posting of my own... I've recieved help from TTP and many others and I'm very thankful for this...

I can totally understand where TTP is coming from after the hours and hours of trial and error it's taken to get my car the way it is now. I've been working on my map over a month now... (granted I've added alky among other parts) and I won't be calling it "done" for some time.

Well anyways I'm getting way off track here... i love you guys lol

I am through exchanging barbs. Your actions speak for themselves. I wish you well.

I have seen stock timing on an evo 8 with 20 knock counts. I haven't heard about up to 7 counts being ok yet though until this thread. I didn't know that's ok. I have been keeping mine under 3 counts. it seems to pull way to much timing when its over 3 counts.

This they do, and so do my customers...

One of my actions included tuning this GT35R+TTP meth injection last night: https://www.evolutionm.net/forums/sh...5&page=1&pp=15

Scott's tune is dead on after driving around today and looking at my boost and my AFR they are spot on. Couldnt be happier! You wont be sorry if you go to TTP! He really knows his stuff!!

I agree that the map base is meager at best. But, the stock ECU tuning knowledge has been closely guarded, hence the defensiveness from a lot of tuners who make their living from it. But, as you said, it takes time.

I agree, at least somewhat, that most maps will be useless as a drop in. But that doesn't negate the value of seeing the source code and learning from exchanging information related to the study of cause and effect. The parameters are finite and the components all obey the basic laws of science as we know them.

As for the obsession with knock, I think it is an easy "shiny bauble", but I think it is understandable considering the destructive potential. Unless you have a lot of experience interpreting the data and observing/correlating the results in real life, then you don't have much else to go on.

But I am a little shocked at the removing of logs.. I can understand not posting the map.. The logs however are a diagnostic tool, given enough time you can extract useful data on a map from it, but its no longer a map or any property of the tuner.

I do think people are getting a little knock crazy though.. I posted earlier in this thread, or in another thread about how the ECU seems to respond to knock.

Knock is something engines have ALWAYS dealt with.. Its something you will ALWAYS get.. Minimizing knock is a good thing, but you won't eliminate it, keeping counts as low as possible under varying conditions is the goal. The truth is, its rare that you will get sustained drastic bouts of knock that will do immediate damage unless you are tuned on the very edge, and then force the engine to continue to perform. Damage to bearings, pistons, etc, are due to tuning, either too much cylinder pressure (timing), detonation, or too lean, but generally it happens over a sustained period of time until it finally fails.

Does this mean you can throw caution to the wind? Of course not.. Careless tuning reduces the life of your engine and it will ultimately perform worse than a properly tuned engine. However low knock counts, periodic random knock (generally noise) is unavoidable and sometimes just can't be completely eliminated. This is where tuner experience is absolutely worth the money for his time.. A tuner understands the difference.. This is why the ECU generally pulls timing momentarily when you get high knock counts in a short period of time, but alters the octane number when these knock counts don't subside over time.

also, a knock count of 3 at 2500rpm, is SUBSTANTIALLY different than a knock count of 3 at 6000rpm, this is where those knock filters come in, they set the threshold for the intensity and volume of different frequencies. A knock signature at 6000rpm becomes harder to discriminate from noise, because the background noise is so much greater.. Thats why low counts are important to watch, but its more important to watch how the ECU responds to it.

Unfortunately this goes out the window when you change the harmonics of the engine (removing the balance shafts, or a stroker motor) Even wear on the pistons and rings will generate more noise over time.

Let's get this straight.

A tuner takes Mitsu's property.

Changes a few values--artfully of course.

Resells Mitusbishi's property that they had no permisson from the true owner to alter or resell.

States that it is their sole property and restricts use and distribution of "their" property.

Makes sense...

Sooooo... back to my original query...

Does anyone have any information to share regarding frequency and duration as it relates to how the ECU interprets knock sum?
