I was wondering how much fuel to add/subtract at Low Throttle to make these cams idle a bit better. Anyone else still using the old school S-AFC? I also read on here that retarding intake 4 and exhaust 1.5 realy smooths things out as well.

 

I have the 264/272, which I know are different than 272/272. At 800 RPM I am subtracting 8%, this is with 680cc injectors and 255 pump.

 

I only have 264s but really the best way to clean up your idle is to add timing, which the SAFC cannot.

I tried adding and pulling fuel but wasn't able to fix my idle until Turbotrix threw some timing at it with a reflash.

 

Looks like Buschur Flash is in the near future.

 

anyone tried to increase the idle to let's say 1200rpm ?
