Just into third week. Very pleased with mpg especially around town and rural roads. Didn't do bad plowing 8-10" of wet snow for 9 hrs. last Fri. either. The city/rural is running 14.5-17 mpg. Highway trip 255 mi. @ 69 mph- 1725 rpm averaged 20.3 all HC. It seems a little better on SW2 on mpg- much snappier throttle response. Still testing/playing haven't run SW3 yet and I don't drive like I stole it either. Plenty of torque low end - haven't pulled a trailer yet. BTW did I see an update for the 67MEJR on Mads site? Have to check it out tomorrow.

 

Had my smarty jr s for 3 weeks now
no deleats, running in tow mode, first two tanks 15,5 and 15.4, third tank after new update was 16.4 all hand calculated.
The computer is running within .6 of hand calculated mileage sometimes up somtimes down

Runs great, very snappy

 

just got my jr Saturday. Loaded it up, but haven't had the truck out of the driveway yet...

 

is there any way to put the jr67ME to the north american version so i dont have to do deletes?

 

the whole point of the ME version is to run with deletes. not deleted? run the jr67 and download the ME software when you do decide to delete down the road...

 

BTW, I'm seeing ~2mpg better on SW1 during my commute. Throttle response is much better and acceleration on the onramps is dramatically improved

 

how do you put the jr67 software over the jr67me software or can you do that?

 

new to the forum, lots of good info. have the smarty j67me and delete pipe in route, can someone tell me (probably in directons with the smarty) do you do the deletes first or install the tuner.
thanks, jchaskel

 

Yep...hardware (tuner) is the same. Just download the tune you want (jr67 or jr67me) and load it on the tuner.

 

smarty is great love the power on sw#2, however sw#1 i get a lil bit of surging. Anyone have this problem?
