Title: PC5 recommanded AFR
Post by: francky2000 on December 09, 2009, 09:19:37 AM
Hi,

Does anybody recommand a specific Air fuel ratio for the PC5 on the raptor?
The PC5 comes with 13.2 all the way.

Thanks

Franck

Start at 13:1 and work from there on the dyno and see what your combination likes. Tune for max torque instead of max HP.

I think he's using only the Auto Tune and asking what he should be running.

There's a few that have had issues using the Auto Tune. Give Colorado, Gunz, and Preddy a shout. They have good reviews..... :help:

The problem is i don't have a dyno near by...
I am confused as the best ratio should be 14.7 and it comes at 13.2. is there some changes to make here on the required AFR?

PLease Heeeelp!

14.7:1 is too lean, 13:1-13.7:1 is about were it needs to be above 5k rpm for best power and 12.5:1-13:1 from idle to 5k for best torque.
