Economy setting w/Smarty Jr.?

You update the Smarty from the web, with new software; then upload that to the truck.

What exactly did the update to 5. 12 do for you?
I have the 5. 08 and ..... of course..... I can't use a Mac to do the update, so I have to go find someone with a pc who can do it for me.
Well, anyway..... what improvements have you seen with the 5. 12?

The main thing was a major decrease in smoke... its pretty hard to make it smoke bad unless you really (purposely) lug the engine. That was my biggest complaint with the JR, and that update made it about perfect for my uses.

Less smoke is a good thing, but no noticeable mpg gain?

Jim, I will update your smarty for free.

The difference between the 3 software (Revo settings the same) is fuel duration. The timing is the same (again same revo settings) from SW1-3. SW1 is timing only and the power gain is in the mid range, with the max power only being a couple hp above stock. SW1 make the biggest difference in the 1400-2500 rpm range, where the extra fuel of SW2 and SW3 keep that power gain all the way until the defuel limit (2900 stock, and not sure if Smarty raises that).

I have ran SW1 mainly over the last 55K Smarty miles, and SW2 some. I will be running SW2 at a minimum now based on my mods. SW1 still does everything I need it to, but I have the supporting mods to run SW3 all the time, if not more, and will see how I like SW3 when towing. . I don't need the power, but why not.

One of the things I like the best about the Smarty is you get full timing (based on revo settings) at any SW level, so on the lowest setting you get the full benefit. To me timing is very important on a HPCR, and I don't want to have to run a full on performance tune to get the full benefit of timing like you would on other tuners.

Thank you, Bob. That is a very kind offer. However, would it not be more simple for me to find someone locally with a pc and just do the online download? I would need to mail my Smarty Jr to you to do the download... correct?

Hi Bob,
Well, I bought a USB 2. 0 cable and took the Smarty Jr to a friend's house and plugged into his pc.
After about an hour of trial and error, we were not able to download the upgrade. Maybe because he has Windows 7... ??? I sure don't know, but I think I will need to take you up on your offer to update the Smarty for me.
This is Friday evening, so I will try to call you on Monday and make arrangements with you.

Bob,
Thank you for updating my Smarty!
