Hey guys,

I have a 99 Firebird Formula with the following mods. I am also tuning with a V2. I do have some experience tuning with XFI and a Haltech. So while Im not completely new to tuning, Im no professional either.

LQ4 Block
LS2 vette rods/pistons
Mild cam (less than 217* I think)
Ported 317's.
Fast 78mm intake
42lb injectors

As Im messing around with the settings, making little changes here and there such as Inj Flow Rate, g/cylinder and such, I keep coming up with the same problem Ive had since I got this car running. It idles at 1500-2000 in park. In gear it comes down to 1100. I force timing to 6* in my dashboard and the car idles along happily at 900.

Before I start randomly removing timing from the tables, I was wondering about what adjustments I should make. In the "Base Spark in Park/Neutral" table, its reading 18* from 800 and down to 22-35* range from there till 2400 RPM. Should I bring those numbers down and smooth it back out and see how it goes?

There are better ways to reduce idle speed. Without seeing the tune it would just be guessing.

Ill post it up in a few, my laptop decided to be a ******* a few minutes ago.

Keep in mind before you guys bash how bad the tune is, I only just started messing with it. Mainly correcting settings and trying to get it to idle. Everything else has been untouched.

Edit; Either my battery or my laptop just died.
