i'd love to know the real reason for this as it's the reason i don't run a dynoflash map anymore, it just doesn't seem safe to do this and i can't get an explanation as to why. tuners that use this method just beat around the bush and won't explain it , so like many others, i assume it's to cover up a not-so-great tune.

If I had to guess I would say where a car has ghost knock and wont advance??? I have no clue honestly, that was a wild wild guess.
In the few cars other then mine that I've tuned I havent seen it, but you guys tune 100s of cars a year atleast.

The one thing that you forget is that sometimes the car knocks when there is no real knock present, and the ECU will still pull timing. Sometimes it's hard to replicate this. Sometimes the fuel that you tune on is better or worse then the fuel that you get the next week, sometimes the air is worse, etc.
I think that you have a good grasp on tuning, but you try to play yourself up as a guru and you are not.
That is of course, just my opinion. I wouldn't have said anything because it's not really what I'm about, but you chose to attack me in another thread and try to discredit what I was saying because it went against the grain. Specifically this:
Personally, I think that you have a minor bolt on car that I could tune in my sleep, yet you post around here acting like you're Sean Ivey. I'm sorry if I've derailed this thread, but seriously dude stop, you know enough to make yourself dangerous and that's about it.

In the thread you refer, you said that it was OK to run an Evo at 10 deg advance at peak boost, because you had done it. The OP had a pretty stock car, but you neglected to mention you ran that timing on your car with cams, an big turbo and not on pump gas, not exactly apple to apples was it?
So you don't seem to like the fact that I have disagreed with you, yet when I posted in different thread in agreement and made an effort to be friendly, you just got sarcastic. So your in the knock is OK camp, fine, but if others don't share your view you get a bit testy.
Can you flatten my boost curve tonight? Sweet dreams.

I've tuned non-cammed evos to see 10 degrees at peak boost without a trace of knock. I've said my piece though, so I'm done arguing about that statement.
About the boost restrictor, i said in THAT VERY post, that I was unsure. I had my BCS for about 3 days before i put a MBC in, that is why I didnt know, and I had recalled people buying used evo's that had MBC's previously that had been taken out to be traded in and people not seeing full boost because there was no restrictor pill in the line, this is why I was confused, and admittedly so.

Stock injectors, but I had thought maybe somehow it snuck out of the factory with something other than 560's. It had the type 13 ROM so I couldnt look at scaling so I switched to a T15 and it was 513 like stock and is fine. The problem didnt go away until the maps were all the same in my car. I have tuned plenty that didnt do this, I for some reason have one that does.
On the same wavelength anyway...Sean said some cars just need it, end of story.

sure enough the low and high octane maps were matching giving the ecu no way to correct the situation.
explain to me why you'd send out maps like that to a car you don't know anything about as the standard flash?
I just don't think it's a good idea to force the car to plow through with that much knock.
I could get away with matching maps on my OWN car because I'll make sure the map is perfect and I'll also monitor the engine.

no disrespect to you sean, i was looking for al to give me an explanation. some cars you CUSTOM tune may need it done, or you know it has 0 knock so it's a little safer. but al did this to my maps on an email flash, so how does he know my car is one of the ones that you just HAVE to do it on? since he can't explain it to me, i use another tuner that will explain the reasons he does certain things to my maps.

A big part of the problem here is most people have no clue what the knock #s mean, is 15 high or low? Is it dangerous? What impact does it have on the engine long and short term.
Without this type of information, it is hard for some people who are only starting and are only tuning one simple combination to determine what it is they are shooting for, also some tuners have a different approach where they let the car run on the knock control.
Experience is a huge part of the tuning equation.
Ask yourself, "how much knock would it take to push a stock rod through the block?"
