UDC Pro 0.0.0.12 was released last Wednesday and I've been re-tuneing my truck. 

 

I did my last tune revision at the end of last years tow season and have been very very please with how it preforms so I really have done too much with the big tables, timing, rail pressure, and duration. 

 

I started off looking at the fuel limiters, of which there are many. Since my truck is used as a towing/hunting/camping truck I am not going crazy with the fuel. I was able to improve spooling and mid rpm fueling but utilizes the stock limiters to have a smoke free experience. I can now put my foot on the floor at 1500 rpms and not have any black out the tail pipe, yet it still lights the turbo and takes off as fast as before. 

 

After a few drives it feels like I have all my power thou I won't know until I hook up the trailer and head into the hills. Since my duration table hasn't changed and my timing is the same it should be the same... just depends on how the limiters are setup. 

 

Then it was time to address the pilot injection event. I had already completely killed the post even in my first tune. The pilot on the 04.5-07 and the 03-04 is HUGELY different. The DEMO and licensed version of UDC Pro have all the stock files from 03-16 in it which makes comparing easy. The 03-04 uses a smaller pilot with less timing and even shuts it off at higher rpms and loads. Before even looking at the 03-04 stock tunes my intent was to kill it above 2400 rpms from 0%-100% and above 2200 rpms from around 40%-100% load. 

 

Because I have the 03-04 piston I studied the stock stuff for 03-04 pretty hard and it gave me about an 80% solution. I have setup my pilot to be much, much, smaller and not have the huge timing advance that the 04.5-07 did, as much as 57° ahead of the main event! WOT at 2900 rpms the pilot was firing about 58° BTDC! The 03-04 only uses about 4-5mm3 per pilot shot while the 04.5-07 uses up to 15mm3. 

 

I was able to cut my pilot WAY down and bring the timing back a bit on it too, as well as drop it at the rpms I mentioned above. The transition from pilot to no pilot is very smooth and quiet, and the reduced pilot in normal driving rpms is an improvement as well. 

 

I have noticed my load is a little higher at idle now but I am guessing that's from a smaller pilot and thus a bigger main event. 

 

 

It's also easy to tell there was a lot more emissions restraints on the 04.5-07 engines than the 03-04. The 03-04 only has 2 altitude adjust tables while the 04.5-07 has 5! Aparantly the EPA was worried about emissions while towing at 18K feet... 90% of owners will only ever operate in tables 0 and 1 and the rest will likely never get to 3-4. Tables 0 and 1 are both for the same elevation, up to around 10K feet, but have different tables and triggers based on intake air temp. This is handy as you can mess with timing with a very high IAT. The tables start to blend at 90° and fully into table 1 at 180°. 

 

I was also able to drop my CC engage speed to 20! I have always hated the 35mph minimum from Dodge. 

 

As for licensing dongles only 1 is needed per tuner, not per VIN. So if you have a MAIN or VIN dongle you can get a Pro tune from a tuner with no additional dongles. If you want to do Pro yourself you will need a Pro license dongle. 

 

So there it is in a nutshell. There is also some real time tuning capabilities that I haven't messed with yet, but plan to purchase the hardware to do so shortly. 

 

 

Where  did you pick up your dongle? I'm looking at working on my brother's 05 over the summer.

 

His acts VERY weird at >10K elevation. The rail pressure spikes to 23K and stays there. 

On the Smarty web site a user posted this information for the UDC Pro dongle.

 

"1 866-211-1533, call these dudes. The key is $349 until the end of the month, then $449 I think. These guys have the key in stock now."

I got my dongle a couple months ago from MADS/Smarty... but I couldn't use it until this weeks release. 

 

Tyler, I am guessing his rail pressure is going to 26K? This is fairly common and one of the things I have been very excited to rectify with Pro. I have seen it happen as low as 3500' with the proper ambient pressure and IAT but generally it occurs above 7,500' and a 70° IAT. Marco and I have discussed the issue for a couple years with a couple attempts to fix it; however, the fix will be best implemented in Pro. 

 

Let me know if you have any questions when you start to tune. 

I have around 4K miles now with pro and it's been great, but still now towing... been an odd year for that but I should hook up to the trailer soon. 

 

The biggest thing I have done is with the pilot and killing most of it has been very very nice!

 

I am currently playing with fan control as it was just released. 

We also have control over the 2nd WIF sensor option so my 2nd senor will be going back in at my next filter change. 

 

I have installed the ComMod and now can tune/flash in real time. It's great for messing with small parameters you want to test prior to a 5 minute flash. There are some tables that deal with fueling during 0 load rpm drop (think rev to 2500 and let off the throttle or shifting a manual trans truck). Tuning them in real time is sooo much better than a full flash. A small tweak on the laptop, transmit the change and check. It's literally that fast. 

 

I did cut my pilot completely out the other day and it sounded like a 24V. For the little testing I did my timing was fine where it was but the sound was much different. I may mess with that more in the future but a lot of the pilot stuff cannot be shutoff in real time, but timing can be. 

I did my first towing with UDC Pro this weekend... and WOW. 

 

The only really big difference to the power portion of my tuning is that the pilot is removed at the rpms/loads I pull hills at.. so just a single event. Otherwise pressure, duration, and timing are relatively unchanged over the last 2 years or so. 

 

I made some tweaks to the OEM fan programming and it was noticeable. 

 

As long as I have been towing with my truck I have never heard the fan come on based on ECT's, ever... The OEM programming should have it start to engage at 210° but mine never did audibly, but I could see minor rpm increases with my touch but never enough to lower ECT's. 

 

I revised the initial ramp up rpms and ECT. I lowered the initial ECT to 207° since that is where the thermostat is full open. 

 

The grade I pulled this weekend is horsehoe bend hill. It's about 2 miles long and 6-8% for most of it. I normally pull the hard spots at 80% load, 1200-1250° EGT and 213-215° ECT running 63-65 in 5th and 2300-2400ish rpms. 

 

This last weekend I weighed in at 19,020 lbs right about 3 miles after the big grade I pulled. 

 

I pulled the hill at 1190-1200° peak, 80-85% load, and didn't hit 211° on ECT's. I would watch the ECT's hit 207° and the fan would start to come alive on the touch and then I would hear it!! The ECT's would drop to about 205° and the fan would disengage. It did that 3-4 times over the course of the hill and the highest it got, on the first cycle, was 210.98°. It didn't break 210° on the other cycles. 

 

Without the pilot (OEM pilot is around 12-13 mm3 at those rpm/load which is more than 10% of the main event) the load was a little higher than normal but the EGT's were a hair lower than normal and it was hotter than average with temps at 101° at the base and 97° at the peak. 

 

All in all.. UDC Pro FTW!!

 

 

The towing experience with Pro is as much better than UDC as UDC was over Revo tunes. 

You's guys talking about your "dongles", makes me laugh!!!!  

 

This is a family website isn't it!!????

You should see the pile of dongles I have lying around the house....

I thought most of y'all only had 1 "dongle"!!!

I'm a pro... and need more than 1

But does your dongle have bluetooth?  Mine does  bluetooth makes everything better.

300 mile tow yesterday. Much of the drive was at 70-72 and I really like how it drives. No real change in mileage over the previous trip on this road, but the truck is much smoother and much better overdrive power on the hills. 

 

I am certainly down a little peak hp based on the lack of the pilot (based on a little more load than normal), but it all runs a fair amount cooler on EGTs. Even at 5000' and 75° I peak out at 1200° in 6th WOT at 2000 rpms. I haven't decided if I'll add any fuel back or not. I'm not sure I need that much power in 6th and its rather nice not needing to watch the pyro in 6th as much. 

 

Flat ground at 72, just over 2000 rpms, is about 40% load, 1000°, and 12 psi. All numbers I am quite happy with. 

 

Thats just the camper, not quads, and about 17.5-18K GCW.

I noted you stated stated you got your truck to sound like a 24V..  What did you have to do via UDC?

 

Only bumper here is I have a 2004.5 .. I would really like to just do as you noted .. And have tried / tested..  Having never even looked / messed with a UDC I could be 6 months away from hearing a 24V ?

It takes a single event tune, which has to be done with UDC Pro. 

 

Do you have UDC (S06 or SJR) or UDC Pro(Touch or MM3)? 

Thx for typing bac ..

 

Yes I have a S06 ...

No way to get a single event tune with that tuner. 

 

Let me know if you want any more info on Pro and a MM3
