The temperatures are dropping around here and I was wondering if I should pull the predator out and change my timing? My custom tune has quite a bit of timing (9-10 Degrees advanced I believe) and I was just wondering how the weather affects the that?
I thought that was the rule when installing a nitrous kit.I'm actually wondering the same thing. My car pulls much harder now that it’s getting cool out. But I notice that once the engine warms up she will ping. I think I will drop my timing buy another 2% bring it to 4% below the custom tune I have. Are there any bad effects on lowering the timing? I heard that every 25HP increase you should lower the timing by 2%.
I might be wrong, but I've always thought you could add a little timing in cooler air.
The theory is that when the engine gets hot, the EEC retards timing. Too hot cylinders are prone to pinging. Hence, when it is cold out, the engine is not so hot and you can afford to have more advance.Sorry for being off subject, but it was brought up...The general rule for nitrous is every 50shot you pull 2* timing.
Also, im a little confused...So do you add or subtract timing when it gets colder out. I thought you would take some away. As it gets colder, the air gets denser meaning the engine gets more air. More air = leaner. On top of being leaner, why would you want to add more timing?

Yes cooler air lets you pull a little more timing. You could probably pull 14^ safely while running 91-93 octane.

9-10 degrees is not alot of timing
Thanks, my tuner didn't explain much to me.. Thanks everybody
