SAFC
 
I am running a z6 with a 14b turbo and 450 injectors and prolly around 7-8 psi. i need to find out what i need to set the Safc at. I believe i read -36 for boost and -26 for idle but i cannot remember and i want to make sure.I also need to know if i need to rotate my distributor any. Thanks Austin

read the faq, i thought it was like 40 for idle and 36 for boost, then add more fuel per 250-500 rpm. and with an afc you should be lookin at retarding the dist. almost all the way.

right from the faq

1) 240/450 = 0.53
2) 0.53 - 1 = -0.46
3) -0.46 * 100 = -46

So we have a 46% difference, we add our 5% for injector latency compensation, which leaves us with these settings:

1000 - 40%
1500 - 40%
2000 - 39%
3000 - 38%
4000 - 37%
--- VTEC set to 4400 RPMs ---
5000 - 35%
6000 - 34%
7000 - 34%
8000 - 34%

Can I use these same settings for a Non Vtec DOHC ZC?
