Just got my Smarty Jr. What is everyone's opinion on the best setting for MPG around town and then a highway trip every once in awhile. Tow a small trailer once in awhile and a 2 place snowmobile trailer in the winter. Thanks Pete

set it on sw3. the problem is going to be the teenage kid in you with the added power and throttle response. keeping your foot out of it is a learning curve and once you do that, the gains will come but not much

EDIT- scratch that unless you have tranny work. do sw2 timing 1 and be good

pete97

Ok thanks.

I've found SW1 and timing 1 to get about the best mileage.

I sometimes tow a light weight trailer - about 5,000# or so. Same setting feels good and gets the best mileage then, too.

Turning the PoD down didn't seem to change the mileage much. But I keep it at 70 when not towing to take some strain off the drive train.

With a stock auto I would run SW2 TM2 TQ4, if you go to tow heavy drop it to SW1.

Thats stock!

SW1 is timing only and TM1 is stock timing. All you gain is the tq management, but that doesn't effect cruise mileage.

Ok I will give SW2 a try the TM2 and TQ 4

When it is slick out I go to sw1.

There must be something more to it. At that setting it definatly runs better and gets better mileage than the stock tune. The Butt-Dyno often lies, but the math never does.

Well I ran SW1 with the standard defaults on the trip to camp. I got 20mpg but the bed was full and the cab had 5 people. I ran SW2 TM2 and TQ4 on the way home and got 23mpg. I was seeing 26-27 for bit but the hills of PA kills that mileage !!!!!

It could be the tq management helping you on the bottom end.. But SW1 TM1 is stock other that tq management. SW1 TM1 TQ1 would be stock.

Id kill for 23 in mine. 26 would make my little fella stand up in my pants.

Im lucky to get 17 with the same rig you have, doing nothing but highway driving at less than 70 mph (about 68). guess I gotta buy a smarty

Sounds like your reading the overhead, or you fill up every few miles...

I can easily read 24+ on the overhead, never actually broken 20.

AH64ID...

I've currently been running SW2, TM4, TQ2. Seems to be plenty of power till the Garmon's goes in, and I am happy with the throttle response and driveability of the truck (she seems to really like this setting). However, if I were to "switch my seeting around" to TM 2, TQ4 what can I expect in changes? (effects to throttle response? smoke? etc...)
Not to concerned with MPG right now considering my daily commute is 15 miles roud-trip.

Thanks...

Less smoke and a little more torque management. Your trans would like you better.

Thanks brother....Boy do I feel out of the loop. I just realized that there is an updated version (19) that's available as of 7-11.

Have you run the tune yet? Any feedback on this one yet?
I can't remember what version I'm running, but I dowloaded it the day after Father's day (June 19th)
