What do you use to retard your timing?
What do you use to retard your timing? I was looking into getting a timing tuner, so I can still run my car with the N/A tune on the street. I dont really want to have to put in two different tunes every time that I run the nitrous. How are you guys doing this? Any help and suggestions would be great!

You can put a resistor where the IAT goes to trick the computer into thinking the air is real hot, and it'll retard timing accordingly. Only a couple of degrees, though. Or, if you're going to tune it with ls1edit or hp tuners, you could adjust the timing tables for that intake temperature & use a relay on it, so when you spray the resistor switches in, the IAT shoots up and the computer uses the timing you put in the table for that temp range.

I haven't tested this yet since I have sprayed this year yet... but I believe this should work... (requires HPT or some PCM editing software)
for low IAT values I just pull timing... since I don't drive the car in the winter/really cold weather should work fine
but the resistor mod should work fine too on a stock PCM w/out editing ... looks like 122* or higher it pulls 3*, 113 pulls 2, 104 pulls 1

Do a search on the timing tuner and you will get alot of information.
