I have being trying to get my TCU to Jerry for the longest time and finally today with it winding down for the holidays, I got the chance to stop by and have the meistro do his thing.

I have to say that the tune is so worth it. Smooth shifts are the order of the day and those shifts happen quicker than before.
I finally have true M mode so I have to learn the shift points all over again. Even in M mode before my nanny TCU would shift for me. Now the cluster glows a bright RED telling me to shift LOL.

Driveability at lower RPM's seems improved for me too.

Thanks to Jerry and the Eurocharged team for getting this done for me. If you were on the fense on this mode all I can say the smile alone is worth it!

I am so torn on whether to do this or not. I have a modified valve body in my car that improves the quickness/firmness of shifts but I am wondering how the TCU tune may work with the modified valve body. It looks like the videos of peoples tach with TCU tune jump faster between shifts than mine does, but I suppose the tcu could be holding me back some even though I have a modded valve body to increase line pressure and quicken shifts.

Get both and report back. This is a very good upgrade. It certainly makes the car sportier.

Did any of you do the pedal reset?

BenzoDoc

Swung by the shop today, unfortunately missed you but saw the car!

Glad you're liking the tune

I am half on the fence, I just dont want to have any kind of problem for over doing it or something. Maybe I should inquire about this with Eurocharged.

This is a video of my gauges with the modded valve body, the shifts are firmer and quicker but I am just wondering if they could be even quicker than this with the TCU tune. Then I am curious about how some mention the car feels stronger like it gained power after the tcu tune.

I use my paddle shifters so much more now after getting this done. They actually respond now. I'm glad I got it.

do you have the E63 cluster? so Jerry can make the shift light option work? did it work before the tune?

berti_00

i did my ecu and tcu tune and my traction triangle hasn't flashed as much as it does now lol :/ good times

Hoping they come out with this for the 63 soon. Anyone know if it is in the works?

I received my tcu back from Jerry and I must say that I expected a little more from the 1-2 shift. I have done some spirited driving but haven't had a chance to try a WOT 1-2 shift. If the float between the 1-2 shift has been fixed, I'll consider the tcu tune a success.

My tcu flash in my 06 gto improved my quarter mile time by .2!

After the TCU flash or before?

grantwoodtx

Yes I have the E63 cluster. Not sure if it's part of Jerry's flash but the red flashes when it know you need to shift. It never worked before the TCU flash.

urbamworm- Who did your VB? Could they make you a more aggressive valve body? The ones they make for the 4R100 in the Lightning are awesome, and bark the tires on the 1-2 and 2-3 shift:

I can't wait to get mine back tomorrow!!!

Which car are you putting this in? and please give us your feedback

munich55

My tcu shifts up automatically even in m mode by high rpm.
Will it still upshift in m-mode after the tcu-tune?

blackbenzz

Its going in the E55 which already has a valve body and torque converter. Clk55 going to go under some major surgery so tcu tune fit that is on hold for a while

grantwoodtx

No in M mode the trans will not upshift automtically.

What is the TCU tune cost?

blackbenzz

I think there is special pricing still available for $450 + shipping. Normally $600

Ahmad, who did your valve body and what stall you got? My tcu is also enroute for the tune.

Saw on another thread about this, where someone asked if the TCU tune could eliminate the granny-shifting transmission adaptions that inevitably seem to occur - IIRC, Jake replied that unfortunately that couldn't be done.

It got me thinking... once when I had my TCU adaptions reset by the dealership, getting the car back felt like the tranny had a new lease on life - quick, responsive shifts in C or S. It practically felt like the programming had been tuned, it was so different.

So, my question is, has anyone had the TCU tune long enough and done some easy driving in traffic for those softer-shifting adaptions to come back? Does the TCU tune at least help mitigate how sluggish it gets in C or S, i.e. does it narrow the range of adaption?

Well I did all my Trans stuff years ago before any Mercedes tuner offered anything. I believe eurocharged now offers a torque converter. In the E55 the valve body and torque converter was done by IPT. On my Clk55 I have IPT torque converter and fully built Trans by southern hot rod. Stall is around 2800ish but can't use it in the clk because it snaps axles like twigs. Let me know how you like your tcu tune

c32AMG-DTM

Can/will DSS make you some beefy axles?
