3500 Four Door 373 6speed Truck Owners! What are you running your Smarty Jr on? What fuel economy are you getting? Auto or Stick?

kandgo

Hello?? Anyone else driving a 3500 4 door 2wheel drive with a Smarty Jr outthere?? What's up?

rockcrawler304

My truck in sig is getting 19mpg mixed 80 highway 20 city driving. SW1 TM2 TQ2

Will go back to SW3 after the clutch is replaced

Thanks Rockcrawler for the response, I would imagine a 2500 4x4 w/manual would be close to the same as a my truck. I just re set my Smarty to SW1 TM2 TQ4 and POD to 75. Was just wondering what others are doing out there. Would be great if once we settle on a Towing Setting and just Driving Setting to put em in our Signature line for others to see????

Somewhat close to yours, my dad's '06 3500 SRW 4x4 MegaCab 48RE is showing roughly 19mpg according to the overhead/lie-o-meter. Hand calculated comes out to about 14-15mpg. I know the transmission has a lot to do with it. Smarty Jr. settings are SW-3, TM-Default, TQ-Default.

My 03 3500 nv5600 gets 25 by the lie-o-meter, and 19 hand calculated, with smarty on sw7.

I am giving SW3 TM default TQ default and Pod on 80 for awhile now. Will report back on what it does.

I run SW2 TM4 TQ4. I have version 5.13A and for whatever reason the throttle is far more responsive on TQ4 than any other setting. The truck runs great, minimal smoke and I treat my automatic transmission with great respect. I get about 21 mpg hwy and 18 average mix of town and hwy. My trans has a billet torque converter but it is just habit apply power smoothly.

Sig truck gets 16-19 hwy, 16-17 fwy (80). I have ran SW1/2/3 with no change in mileage.

Here is every fill up I have ever done. I don't DD the truck anymore, so the avg economy has gone from 16.5 to 15.7 in the last 2 years.

ive recently switched to sw1/tm4/tq2 and i like it, but the truck loves it! the thing i like most about sw1 is i dont have to worry as much about the trans and i can drive the truck more aggressively than on sw3 and it doesnt effect mileage near as much. ive also thrown the rokkrech sensor back on at full advance and i love the way the engine sounds/feels. ive never wanted a drag truck i want a tractor-trailer. sw3 just started feelin to top endy, meaning i felt like i had to go 83mph to utilize that setting.

That's potentially a LOT of timing! It must smoke like a freight train and have a constant haze to it.

kandgo

TM4 is allot of Timing!! Well I have been running on SW3 Default Default Pod on 90 and so far so good! Mileage is back up from SW1 2 2 pod on 65

kandgo

Now that is some Fuel Tracking!!!!!! Good Job!

VADERPOWER

AH, i assuming thats still alot less timing than many settings on the smarty senior? am i wrong on this? it seems like , based on threads ive read that the senior cranks much more timing.
