    Pre-Injection

    Does setting this to "off" turn off the pilot injection everywhere, across the board? I would assume main event timing needs to be advanced in order for this feature to work... does the Smarty take care of that or does timing need to be tuned by the user to work with the pre-injection off? In my case, I am using an SSR with UDC. Just trying to understand a little more about what this feature does before I start playing around.

    Cruise Timing for 2005

    I have been continuing to add .5* of timing waiting to see some indication not to... and I'm now at 14* in my cruise region. No knock or rattle, probably a bit more injector tapping (remans) Truck is still responsive and builds boost quickly at the cruising loads Exhaust is clear, no haze Rail pressure reads on my OBD app what I'd expect to see at those loads based on looking at the stock pressure map. Up to 2000rpms going through the gears it seems I can here a little more 2nd gen-esque noise, but pretty faint. Should I keep going until I see some sign I've gone too far? This is a lot more than I'd have expected to get away with! The last tank of fuel only ended up being ~.2mpg better than typical, so I'd like to continue looking for a bigger gain.

    Cruise Timing for 2005

    Bump! I am at around 11.5* of timing on my 06 at 2000rpm in the 12-25% load areas and other than being quite a few more miles further along than I typically am at a given point on the trip meter for a fuel tank, I am not noticing any huge difference in how the truck runs or sounds. Running a Jr, so stock rail pressure and untouched duration. Timing map is largely modeled after the SW3 sample other than cruise region. I am used to hearing injector rattle, and have heard that stock and with all Jr tunes. It sounds like a light tapping and from what I have read, it is common for aging and reman stock injectors to do that. I am hearing a hair more at cruise in the subject rpm/load, but not much. When advancing cruise timing and finding the optimal settings, will it be apparent when timing is advanced too far? I am sure I am getting close to the limit at 11.5*, but want to make sure I am not missing warning signs.

    More MPG - Jr w/ UDC or time to upgrade?

    Are there any other maps/tables available? I know SSR can adjust or shutoff pre and post injection events. Are these tunable in UDC? Thanks a lot for your help, Brian!

    Is there any way to compare what tuners have what parameters available in UDC?

    Looking around and seeing used SSRs for pretty reasonable costs... would an SSR with UDC tuning open up more tuning capability than an S-06 would?

    More MPG - Jr w/ UDC or time to upgrade?

    Yeah, I think for $260 I will just take a whack at the Jr UDC thing. Any other option is a LOT more money... I know rail pressure is off limits, and duration and timing are likely where I'll be making changes. I read somewhere that the Jr UDC software is limited to 25* max? That seems like a lot but common rails are still new to me. This might be starting to get into UDC forum territory... but how much timing does a Jr on SW3 run at light to medium load anyway, where I'd expect to make the most timing changes to improve MPG. Hoping AH pipes in soon... he has guided me well over on Mopar1973Man as well. Thanks for the compliments on the wheeling setup! Had many iterations of tow rigs over the years. Trailer is new last year. I've been into wheeling since around 2010. XJ was driven everywhere on 32s. Tow rigs have included Vortec 7.4 Burb, 95 12 valve 5spd, 2014 Ecodiesel (cool truck, thought I learned not ideal for my use) and now my 06. This truck will be sticking around for a while.

    Brian... I have a feeling you're probably writing me a response right now but after some reading, I can see that I need a Touch or MM3 to get to the next level of UDC Pro tuning. Looks like the UDC Pro dongle/cable kit is $450... plus the cost of either the Touch or MM3? That is more than I am looking to spend, at least for the time being. Is the $260 dongle and cable for UDC the same hardware for UDC Pro at least? Ie if I buy the standard dongle/cable, it would just be a ~$200 software upgrade at a later point if I find myself with a Touch or MM3.

    More MPG - Jr w/ UDC or time to upgrade?

    Thank you! Interesting, OK. Looked at the price of the Touch, I realize good tuning is not cheap but that's a good chunk of change. Couple questions. ANY Smarty product I buy will need the UDC dongle/cable to run UDC tunes, correct? If so, I may pull the trigger and play around with the tunes in my Jr and see what I can do. If it's needed either way, I'm not throwing good money after bad. Other question. Does the Touch actually open more tuning options through UDC than I could get from an S-06 Sr? I'm not a fan of being loaded with technology while I'm driving and like how my Jr stays under the back seat unless I want to change the tune. Can an SSR with UDC give me the same flexibility in tuning as a Touch or Sr? There is a used one locally for sale for a good price. Here are some pics of my wheeling setup. Did a 5400 mile round trip from Connecticut to Utah in October. Wheeled Sand Hollow and Moab. Jeep is a 97 I've owned since 05 back in high school (bone stock at that time.) Now caged, one tons, Atlas, beadlocks, 39" sticky tires... Trailer is a 30' United my girlfriend and I setup for living out of on weekends we go wheeling. Has shower and sink with hot water on demand, full size mattress, portable toilet, and lots of cabinet space. Jeep noses up to the countertop for a good tongue weight. Really simple to maintain while offering a lot of niceties. SO nice having a setup where all that's needed to head out for the weekend is to strap the Jeep down and load the cooler and go.
  10. Hello, I have an 06 G56 w SB clutch, DRW 3500, stock HE351 with 64mm turbine, 178/208 cam, 33" 19.5 tires. Use this truck for towing my tall enclosed trailer with living quarters loaded with my Jeep. Around 12k loaded trailer and 21k combined. Running the Jr on SW3 POD90, best economy I have seen with this truck over the last 10k miles is 17mpg empty with cruise at 65mph and 10.5 towing here in the moderately hilly northeast at 65-70mph. I do like to use the power sometimes but for the sake of mpg discussion, I am using examples of tanks of fuel where I drove normally and under normal conditions (not romping and no strong headwinds.) This mpg is surely better than stock, but I believe there is more on the table. Ideally, I'd like to be consistently around 11mpg towing and 18-19mpg empty on the highway. I think these are realistic goals but I don't seem to be getting there with the Jr right now. Would I be able to get where I want to be fine tuning using UDC through my Jr playing around with timing? SW3 power is plenty for my use, just looking to consume less fuel. Other options I'd consider would be the Sr with UDC, SSR, or EFIlive (since it's an option for my 06). I would like the ability to dial in a tune myself and am a competent shade tree mechanic type but am have no experience custom tuning and don't want to get in over my head writing tunes which has me thinking UDC could be a good option for me. Last thing: third injection event. How much is this hurting my MPG? I have read on here that SSR is the only Smarty product that will kill that. Thanks in advance, looking at you Brian! :)
