what is the difference in advanced timing and no timing?

txarrowhunter

Advanced increases cylinder temp, burns fuel More efficiently, reduces smoke, and better mpg.

agreed you have to play with the timing my truck likes timing 3 way better than 2 and on 4 it pops 1 is ok but 3 made it really come alive with the smarty on 7

Yep, but on a 04.5-07 CR the timing advance really increases low load, pre-boost smoke. It has to do with the piston design.

The 04.5-07, (and the 03-04 but not as much), has retarded timing for emissions reasons. The injection timing was optimized for clean exhaust, not most efficiency. Smarty timing is how it should have been from the factory.

O just go with the no timing

AH64ID

No.. on a 04.5+ you need timing.... Thats the best feature of the Smarty. I run SW1, which is timing only...

txarrowhunter

yup, sw2 is nothing but smoke for my truck

SW3 was tons of smoke until I bumped the timing and dropped the POD to 75.
