What causes 0-2 timing advance?

[phunny]

At idle I get like 25-30degrees of timing advance, but when I make a 2nd or 3rd gear pull it drops to 0 no matter how much I turn the fuel up!?. And one more thing, I just ripped the boot on the turbo inlet(small rubber piece that intake bolts on), where in the world do you get it?

Hey guys, what in the world can I use instead of that rubber piece on the turbo inlet for the intake?

get a new one from the salvage, DSMtrader, or the classifieds here on DSMtuners.

sounds like knock is pulling your timing. Check for boost leaks and fix that inlet hose.

depends on your settings. with 680s you want to tune at a boost setting that allows your ecu to see enough airflow to be close to the stock timing maps. I found it much easier to tune at ~18psi instead of 12psi so I didnt get such crazy timing. But when I did this, my ecu saw too much airflow when the boost came on and timing dropped to 0 even though I wasnt knocking, I was getting a split second of rich stutter. I had to then lean it out a bit at low rpms to get it back to normal, then tuning was super easy. Just mess around with it and you will find a way that your car likes, just make sure you arent running too lean.
