I have been playing with the DA-A and DA-B tables lately. I have been playing in the low load columns.
Something I have noticed is the DA-A table is used when the coolant temp is below ~180F and the DA-B table is used when the collant is over ~180F.
This is on an 04 Sti. Has anyone else seen this behavior? Again this is all in the low load columns, no boost.

TMS,

I just got finished running this test. DA A was set to 3 everywhere and DA B was set to 1 everywhere and DA C was set to 0 everywhere. My Dynamic Advance followed DA A completely. To clarify, the Dynamic Advance followed DA A independent of coolant temperature. This included taking logs well past once the coolant temperature reached 180d.

Are you sure that your learned knock advance was zero across the board? What was your IAT? My IAT was between 68 and 72 the entire time.

Well I won't be using the DA-A,B,C anymore. So no more guessing what the DA maps are doing.

lol. Full static timing in the primary ignition with DA A, B, C all set to Zero? Can I make a compromise suggestion? Fill DA A, DA B, and DA C all with the same amounts. Make them all identical. This will still allow you to have DA while not worrying about what is coming from where. Another option is to get a copy of the special base map that ONLY uses DA A. I myself have run this and it works just fine.

Why am I suggesting this compromise? Because it will still allow your car to have that extra safety margin built-in that is dependent on the IAM (DAM).

This is what I did.

Cool. It's nice that we have options. We can run static. We can run dynamic (WRX Style). OR, we can run full dynamic (STI Style). I like having options

Gimme, I am sick of having to copy-paste the DA-A map to DA-B and C.

[cnstman]

is there a copy of this map for a 04?

The map link was deleted because I caught wind that Cobb might not want those who have the map to be distributing it. I need to follow up with Trey and/or Christian before posting a link to it.

Would you still be able to PM the map? I just want to look at toher peoples maps, and compair to my own.

I had the same map and it still used B

Be wary of setting DA to 0. I have been told that the ecu may be able to add to 100% of the DA, and take away up to 100% of the DA. I have never tested purposely running into negative DA, and I don't plan to.

If it's true though, and you set DA to 0 and tune only with primary ignition, the car wouln't be able to pull any timing if it needed to... this could be bad.

I've seen WRX's in limp mode (from broken UP cats) run more negative DA than they should have been allowed, but I don't think anybody knows much about the car when in "limp mode" (very low AM numbers).
