It's still sort of rough and more of a band aid for now. I used a mercedes tune uploaded onto the module. I just got this done yesterday and we finished at 3am so I didn't mess with it too much. Once I'll drive it for a few days I'll chime in more.

Anyone tried this procedure?

Yes, Avos and several others who have used the blue top solenoids for firmer shifts after I posted about it in another thread.
Very popular amongst the Chrysler Hemi + NAG-1 racer crowd.

Well not entirely. It's just worked out as a band aid for now.
Basically I finally got a hold of my buddy that is a master tech at benz. We used an older MB E320 (uses an egs51 for it's 722.6). We plugged my TCM into the E320 and than used an MB HHT to code the TCM. The problem is that you cannot mess with the values, but pretty much code the TCM to the MB cars on the list. On a hunch and some searching of MB cars with steeper diffs I picked the C280. So pretty much now I have a C280 tcm in the car.
Before the car would go into limp mode as soon as I'd drive it and be stuck in 3rd gear no matter what. If I'd reset it with a scanner it wouldn't even budge and be locked in 3rd.
Now, the car goes into limp mode every other time, however once I'm going 30, and if I clear the codes using a generic OBDII scanner the car drives as in the vid and all gears are operational without triggering codes.
I did the adaptations procedure and the car shifts way better, but still trips the code every other time. Not an ideal solution but 1000% better than being stuck in 3rd.
Avos is working on an affordable permanent fix, but for now all I can say is that the LSD and the 3.58 are definitely worth the hassle. The car is quick and I didn't even do the smaller top pulley yet.
This also settles the conflicting info that I've been finding on the web that EGS51 is write once only as apparently it can be rewritten, but proper equipment is needed.

What do you mean? I'm sure the shift points differ depending on the torque curve and redline.

lying to the TCM
I was looking at the lsd listings again. And a thought came to me.
I previously suggested lying to the TCM using a black box.
Well how about lying to the TCM using mechanical tricks?
The TCM matches rotations based upon signals from the ABS speed sensor. So, how about fabricating reluctor rings that have ... oh say .. (3.58/3.07 * stock number of teeth) on them? That way the TCM sees 3.58/3.07 more "ticks" representing wheel rotation for a given engine speed with the 3.58 installed in place of the 3.07 stocker. That is exactly what the TCM expects/wants.
The caveats are that the reluctors will need to be on all four corners to avoid invoking the ABS, and the speedo is going to be off by 3.58/3.07 as well. Having the speedo recalibrated using WDS may or may not have enough wiggle to take care of this.

Although it is a thought, you will alter much more, as in effect you are also adjusting the ABS braking. It will not be cheap either to make 4 of these abs rotors.
I am still very optimistic that we can have the TCM tune done, just the ratio is the easiest part, but focus is on the program and data now. Unfortunately my tuner was traveling all the time with higher priority work, and couldn’t spend quality time on it. It looks he will have some good time again this week, so I hope I can test something next week.

Bear in mind that the NAG-1 guys routinely run drag type ratios, so they must get their tunes somewhere. In addition, the tranny is also used in the Sprinter van and Jeep Cherokee lines, and they run some seriously low ratios.
Apparently, there is also a ECS53 which is from Siemens, whereas the ECS51/52 are Bosch.
Finally, there is a $250 "off road" version of the TCM sold by Mopar Performance:
My Review of the Mopar TCM P5153332
So once I got the adaptives set it was now time to beat on the car. From a stand still rolling into WOT the first to second shift is very quick and very firm, the shift is very crisp. Now a few RPM's into second gear the change in the car is very noticeable it feels like I gained maybe 20-30 horsepower this is due to the converter locking up quicker. Second gear is simply awesome the higher shift point into third gear is again very quick and firm as is third to fourth gear! The 6400 shift points really help even though power is dropping off hitting the next gear higher feels so much better. Also if you lose traction on your launch a person can burn all the way into third gear and as you do the transmision will shift very quick, I never even hit the rev limiter. Old TCM would bounce off the limiter and then shift and that is with the limiter raised 600rpms in drive.
...
So how does it behave in normal driving? WELL you know its there for sure, it does not hide and pretend to be stock in any way. with foot to the floor driving the downshifts are quick like they should be, its not like stock where the RPMS rise as the transmission shifts down and then you go, it drops and you go. So much improved.
Daily driving like you would with your mom in the car or a trunk full of go fast mods....., shifts are very quick you dont even feel them. The TCM really moves you through the gears quickly, meaning under soft throttle it will shift really early and gets to the highest gear it can in no time. Which along with the second gear torque converter lockup has added a 2mpg's to overall average mpg's which now are around 18.5-19 during a normal week when I drive like an adult.

Had to smile when I saw this.

Good Info.
DiabloSport :: Gas and Diesel Tuning Systems
Looks like the Predator Can change the axle ratio on these cars (Dodges). I wonder if it's possible to do it on our cars using this programmer.

SUPER OLD THREAD ALERT
But what ever came of this? If I clean up the bottom of the car I want to try the x300/xj12 powerlok too.
This is the best thread that came up with info so i'm bumping it

What's the deal with the upgraded torque converter the Mopar guy's are posting about?

That alone may help.
