Yea you are completely wrong. Look where the IAT sensor is on your car.
Why would you need to touch KFTARX? Do you even know what the map does? Please do explain.
There is IAT based timing correction already. Why would you need to adjust the main timing map???
By your logic every winter you would need to tune KFTARX and KFZW... I think you need to put down ME7 and pick up a book that deals with forced induction motors. Some brushing up on the ideal gas law that gets taught in primary school is probably a good idea too :/
This thread is completely ridiculous. To put it bluntly, there is absolutely nothing you have to do when changing charge cooling.
The IAT sensor is in the intake manifold, right after the TB. I don't understand why this means anything at this point. Will you please explain?
Since I am completely wrong, why are you asking me to explain what the map does? It's like you are trying to get me to make up some mumbojumbo or something..
I obviously don't understand what the map does. Please! do explain sir what the map does.
I know you are a super guru when it comes to this stuff. If you are going to speak up, please at least back up what you are saying with some kind of explanation and with some understanding that most people on this forum aren't making a living doing this and are amateurs at best.
I'm sorry you get annoyed when people are wrong in what you are a professional in. (I've read some of your other posts..) Just telling people they're wrong isn't really helping anyone. I don't understand how it would make you feel better either.
What I know about KFTARX ( what I thought I knew about it rather..) I posted already. I didn't even know it existed until it was brought up in prior conversation with another member. I'm not denying I'm wrong (or him), the truth is, it was explained it to me like this after it was brought up in prior(months prior) conversation and I didn't understand. I assumed he was correct and it made sense to me at the time..
"Why would you need to adjust the main timing map???" Don't you anyway? Can't you get just that little bit more timing because it's made "available" via colder IAT's @ the higher rpms and load?(comparing to the stock intercooler setup) I guess really throughout the whole rpm range.
I noticed how you worded this: "there is absolutely nothing you have to do when changing charge cooling" I'm NOT saying this must be done to use larger intercoolers, just saying you can reap more timing advance in the range where the ECU would normally back it off due to high IAT's because of a stock intercooler becoming heat soaked.
As far as my logic with the winter tuning: I live in FL, USA. Winter here is like 76F and sunny and for like only a week...might hit the 30's 2 or 3 days a year...I don't even own a heavy coat or jacket! It's pretty consistent around here...usually somewhere in the 80's.
just want to make it known that my tone here is not "smart-ass". I seriously want to understand what this map is about. I assure you your explanation won't go to waste.
