Hey guys what A/F ratio should I shoot for, so far I tuned it at 3000rpm’s about 11.2 and than starts dropping as the rpm’s climbs up and I am ending up at 7800rpm’s at about 10.8 A/F is that good, I am asking because some Tuners tune it for like near 12 A/F and than again some tune It for like 11 A/F so what is the best and safest tune?

 

Lower the number richer it runs. Tune it in such a way that you don't see a knock, then you may add a little fuel to be on a safe note

 

Tune for 11.5:1 a/f on straight pump gas 91/93octane. The higher the RPMs climb, the less fuel you will need so you can pull more out to achieve a stable a/f. Make sure you don't see any knock figures and if you do try to add more fuel in. Now, this is relative because I have seen cars fold their motors with zero knock and some run great with a few degrees of knock. Depends on EGT/Boost/Timing/Knock/Weather..all figures go into play.

 

thanks for the input guys

 

You have a smart systen try to leat it out to 11.5 and note any corrections over a good sample of driving conditions and see if any kinda corrections occur. You can correct these by adding a bit of fuel of possibly taking out .3 degrees of timing at a time. Also if you can run any config al the time without knocking then see what an additional 1 psi does

 

Yes it’s definitely easier with SMART
