I've had 3 different TCU tunes with 3 different TCMs for my CLS55 from TJ and each has been better than the next. Looking to upgrade again. What codes are you getting? If you put your stick TCM back in do the codes go away and driveability restored?

Just installed my MK Ultra Stage 1 TCU and unfortunately had some major issues which were so disappointing.
1 CEL on
2 car is stuck in Sport mode and wont cycle modes, paddles dont work
3 shifting gears and from P - R or D its extremely jerky and the car nearly hit the garage wall during the cold start maneuvering.
apparently it got damaged in shipping , anyone else had this problem?

Yes I have. The file is not programmed correctly as in he forgot to send the file over to TCU from what I remember/he told me, and needs to go back to Troy to fix it. It was NOT damaged from shipping.
Do not drive the car as pressures in transmission are EXTREMELY high and damage can occur.

What can be achieved in a facelift w208? What I'm interested in is a bit higher shift points ("I'm pressing the pedal just go already d*mm!t") and if it could solve the issue where it does not upshift during coasting so when I press the gas it scrambles to upshift and does so with a jerk.

TJ is great to do deal with. If he does a major update on firmware after you purchase, he will update it for free. You just pay shipping.

I have had an early tune and a recent one. The difference is huge, the newer one is much more comfortable, more responsive and better performing. The early versions were very harsh. Don't know about the other ones but I suspect the difference is very minor. The description it gives on the website doesn't make them seem of much benefit to the majority of people.
I believe the "upgrade" is the stage 1 tune which I assume is what you received?

I am ordering the "race" type version that eliminates the shift delay with the paddle shifters so will give you guys a review on that one.
I have 5 TCU tunes from Troy and the one I race with works really well but that time delay on the shift is really a pain since my engine revs so quickly especially on nitrous.

So installed the "Sequential" TCU from Troy and here are the results.
You must do an "Adaptation " and is mandatory for this unit. to work correctly as it NEEDS to know what the clutch pack gaps are to adjust to the speed/overlaps in shifts. Meaning you are trying to control each shift with no binding-sliding from leaving the last gear into the next, mostly 4rth. You will need 40-50 shifts at low to medium speeds for this prosses to be performed correctly.
You will only have C , S , and M mode, no more Agility. C and S shift a little better than stock and I was hoping for a little firmer but don't really need it for around town.
There is no longer any switch or wiring to deal with, plug and play.
Now the "M" mode !! Very very fast with "instant" upshifts meaning two things, how fast the shift itself is from hitting the upshift button and how firm-hard the shift is. As soon as you hit that upshift button,bang she's in and this was my biggest complaint with these cars. Now that my car makes more power and the rpm comes up much faster than ever I would have my shift light set at 6,300 and it would actually shift at 6,700-6,800 rpm which was no big deal and used to it but felt that this was in no way any type of performance reaction from the ECU-TCU for racing in my opinion. The shifts are VERY firm and instant up and down and is perfect for what I do.
Going back to "S" mode and it's almost stock performing.
So two thumbs up for this TCU and again thanks to people like Troy at MK Ultra who continue to make improvements on an iconic platform and go places that no else does especially with these transmissions.

Great feedback thanks. Weird question but have you tried it at low speed on the street? For example in S mode it goes from 3rd to 4th at exactly 48km\hr at low acceleration for me. If I try the same shift in manual mode it refuses until a much higher speed.

It does need some speed to upshift of course but yes. And remember if you are considering this unit ...it shifts very very firm when you start with harder acceleration up the rpm.
Not for everyone.

Sorry for the late post ..............
Until I drive the car again when the engine is back in I can give you very specific information on it but it is an "instant" shift as soon as the button is pushed and totally changes the driveing habbits of the car.

I would like to upgrade to either the stage 1 or your SLR tune. I have e-mailed him but he must be busy as no response yet. Anybody have the SLR tune?
Stage 1 Street Tune (03-20-23 Update to new car shift performance) gives faster around town/street nice shifts depending on the load of the engine. Wot Fast crispt shifts. Torque Management Overhauled. No bogs/dips in power during shifts during normal driving. Torque Limiters Raised. Agility Mode Included and Modified for faster firmer shifts. No gearbox learning with A mode. This has been updated to shift like a new car now. Blue-top solenoids gives the best results. Most E55 cars have them, 05-06 came stock with them. I can verify through Vin #
Mercedes-Benz McLaren SLR Hybrid VERSION Tcu Custom Firmware For E55 AMG. Speed Shift R Ultimate. After a massive amount of development, live testing, and software editing with MAJOR changes to pressures and adders and many other calibrations as in gearbox learning corrections for lateral and acceleration values for traction control and other parameters. This calibration requires BlueTop Solenoids, Adaptions are cleared and TCU requires an “adaption period of driving” for TC clutch and clutch volume indexes. Comes standard with full M-Mode if you want auto M-Mode option is available… Comes with standard C/S/A modes you toggle with the stock mode switch, Agility mode Included,. . Shifts are unique to my calibration due to clutch pressure adders have been scaled out to give a positive feel throughout the torque curve and rpm range. Slow driving has fast smooth positive shifts all up to wot super positive powers into the next gear with no harshness but a nice fast positive feel. TCC lockup/slip is different than stock m113k tcu values, with no lugging at low speeds that get annoying, This is a daily driver to high-performance driving.

I have the stage one for sale. I had the SLR,DTM and others and saw no difference really. A friend of mine and myself have multiple TCU's and onestly every revision we expext something "obvious" and really don't notice much change.
Trust me Troy is a game changer for these cars and im thankfull he does these, my Stage 3 and the new Sequential unit from him are unbelievablely fantastic but I also need/want firm shifts. With that being said PM me and let me know if your interested.

I received my upgrade from Troy at MK Ultra. I went with the Stage 1. The car shifts very similar to the 7 speed in my SL-500 when the E55 is in "C" mode. Kick down is extremely fast and smooth. The "A" mode is really quick and the shifts are pedal dependent, no gear hunting whatsoever. Transforms the car. This is what should have come from the factory. My buddy who is MB tech said "wow" when we were dialing it in with the Mercedes computer. It's fantastic!
Do it if you haven't.

@SICAMG It appears the TCM I purchased from you has finished the adaptation after a week or so of driving. I like. 
Many thanks for the fantastic deal. Always wanted one but never knew if it was worth the cost. I now know it is. The transmission shifts "authoritatively" is the best way to describe it.

Told you you would like it !! And if it is a little too much you just put it in C mode when family are in the car.
I have had many from Troy and my latest Sequential version is crazy fast in M mode for racing with full pressure. Troy is a game changer for these cars for sure.
I'm thankful 99lightning,Tim, turned me on to him a few years back.
