Great work, I’m really impressed! If you are heading to Germany you could stop by the stern garage. They are tuning manly older mercedes but their work ist really good and I think they could be interested in your tcu!
I have a 2005 Sprinter with a 722.6 NAG1 transmission. The VIN for this vehicle doesn't look like it matches anything on your site. Interested if you plan on updating this in future? Also interested in the security/safety video! Very interesting channel! Great work and hope you have steady progress
I chose to work on the .6 as it is hydraulically safe. Reverse can only be engaged by means of the gear selector, never electrically, and if I activate any shift solenoid out of order, the box will hydraulically go into neutral! So it is super safe!
this is impossible. If you are in 5th, activating the Y3 solenoid would shift you down into 4th. Not 1st. The solenoids are activated in this order to get to 1 to 5, and back down to 1 again: Y3, Y5, Y4, Y3, Y3, Y4, Y5, Y3
I can't figure out if it rev matches and how well. One of my main complaints with manual mode in w219/w211 55 AMG cars is downshifting. It feels like it jus slams the lower gear, causing sudden and unpleasant engine breaking. Can you clarify if this TCU addresses this and if so, what are the improvements in this area?
Great Work!!! presume that all of your testing has been on standard VB and solenoids for the M113 (E55) large 722.6? Interestingly MB did introduce an updated TCU and tune post 2006 on the large 722.6 for CLK55, 63 and E55. Noticeably faster with paddle shifts working in any mode, but still dimwhitted software, and overly nanny protection. Tested later TCU's in my CLK55AMG 2004. Market place tunes of standard MB TCUs are an improvement, but always leave excessively snappy down shifts due to lack of rev matching. I did notice in your video that some snappyness still remains with your TCU in M and S modes on the downshifts, but improved. Do you intend to introduce rev matching with your developments?
@RANDASH HI can you tell me if you can put one more profile to auto profile sorta an E profile to tweak it for max fuel economy? It woud be nice to have like a 30 sec of Sport profile if you give it kick down 😅 Thanks!
Great job mate, will you sell the product at the end? I'm wondering if you will have one for MB Vito 120 CDI, 3.0L, V6, 2009 model. It has the 722.6 5 speed. Thanks
I'd rather not though. It is never sustainable. And, I'm taking working EGS units off the market forever by doing this. So easiest solution is to make a connector and case from scratch for it
Just because why not?. I felt like having too much power is better than having too little. Ryzen also has far better 3D performance than ARM, which might be useful to me later on
I just found your RUclips and watch the video regarding the rx8 you are insanely smart and I need help with My project. It's not a mondain thing for a regular person, might be for you but I deleted my abs which made me lose my wheel speed wanted to know if you could help me out
Hey, awesome work! Quick question about manual mode: Is possible to make it closer to "true" manual? As in rev it like a mad man in first without second gear ever kicking in and maybe even stall the engine before shifting to lower gears on low rpm? Love to throw my w211 4matic cdi around especially winter time, but trans still does kind of what ever it wants even in manual mode on stock tcu 😅
Not really no. Auto boxes rely on pressure generated by the input shaft pump. So you need to have hard lower rpm limits before downshifting or unlocking the converter to avoid serious gearbox damage. Rev matching is near impossible on 124 platform as it's engine ECU was never designed to be told what torque it should make
semi standalone. It requires CANBUS to function. But I am building another module (No ETA), which acts as a sensor gatherer module and relays the data to the TCU over CAN
Word up! I also always wanted 722.6 on my b230ft volvo. So that means, that we have the question: which external signals does it need to run properly: engine torque signal, output shaft speed, engine rpm to adjust the lockup, and what next?
good catch. This is the case atm due to the TCU trying to prefill the clutch packs before moving the new clutches into place. This helps with jolting and also prevents burning of the friction discs. We are working however to learn when the minimum prefill time has been achieved, so we can reduce the prefill time down to when the gearbox starts to behave badly. Atm we are using a 500-1000ms value to be really safe.
@@RANDASH Understood. I am acquiring parts for a fast om606 build and am keen for an autobox, rather than the 6 speed manual from the sprinter. I want both fast and lazy shifts depending on mood 🙂 Im yet to do a proper deep dive on your TCU. How does it implement torque reduction requests to the engine... can data? Have you got a spare output pin that could do this? Also I assume trans-brake is out of the question thanks to the fundamental gearbox design. Keep up the good work
regarding torque requests, it is done over CAN with OM606. We are testing with a few others who have 210 OM606 builds and it so far works fine with my TCU! Regarding trans-brake, the stock valve body is impossible to do this, but if you modify it (Companies can fit a trans-brake solenoid to the VB), then my TCU has a MOSFET that can drive it!
@@RANDASH Any updates regarding the rev match for the w211 E55 ? I’m getting one of those TCU’s anyways just wanted to know if you plan on a rev matching feature on the near future .
Slow shifting, bad software, no plug-and-play support (This TCU can be a drop in for any car with EGS51,52 or 53), mainly though, the stock TCU only adapts in 1 way, which doesn't take into account hydralic wear and tear, which is where issues such as rough shifting and/or flaring come from. We are trying to make an adaptation system that will fix all of that.
depends how you use it. If you are using the TCU to get 50-100ms shift times with 400bhp, then yes. But if you want a stock like experience with it, then no you won't wear it down!
SHUT UP AND TAKE MY MONEY - I ordered one after the first 5 minutes of watching
A video about the security aspects you mention would be very interesting! Greetings from Spain and happy new year
Can't wait to blow up some gearboxes
Great work, I’m really impressed! If you are heading to Germany you could stop by the stern garage. They are tuning manly older mercedes but their work ist really good and I think they could be interested in your tcu!

The NAG52 is an amazing project! I have a W203 C200 with 722.6 its a great transmission.

Dont forget my Caps ;-) Shifting seems as fast as my 2016 AMG DCT Speedshift.

Hello! Great job! What about Porsche 997.1 with 722.6?)
Take a look at the website. There is a Google form link there if you want to try testing the tcu out on a non Merc car
Will you ever work on one for 722.6-equipped Porsches?
@RANDASH

Hey, I’m building a jeep suv (the ecu is megasquirt 3) do you think is possible to run W5A580 (which is essentially 5g tronic) using your product?
Could you please demonstrate where Can b is? Is it the obd2 port? Nothing is working for me. Thanks
You could set up a core charge for the OEM TCUs, to help source the parts you need
I'd rather not though. It is never sustainable. And, I'm taking working EGS units off the market forever by doing this. So easiest solution is to make a connector and case from scratch for it
Great job on this! Is there any chance it could work with a SLK r170 2.3, year 2000?
Is it plug and play? Cant find info about your TCU installing procedure
will there be a way to switch drive modes for w210 chassis, or will it be limited to S/W?
Hi! Love the project. I have a (probably stupid) question. Why did you go for an x86 ryzen PC and not an ARM SBC? Did you really need all that power?
Just because why not?. I felt like having too much power is better than having too little. Ryzen also has far better 3D performance than ARM, which might be useful to me later on

I want one ! Will it work for Dodge Charger they have a nag1 trans which is the same as 722.6 trans just renamed by Chrysler

@@RANDASH ok, so you need to have the hard lower limit to maintain some minimum pressure on the gearbox for it to continue doing it's thing. Thanks 👍
Can this control be use as stand alone tcu? I’m planning to install my 722.6 on my old Mercedes and I’m looking for options,
semi standalone. It requires CANBUS to function. But I am building another module (No ETA), which acts as a sensor gatherer module and relays the data to the TCU over CAN
Perhaps a silly question, but will this TCU work with standalone ecus?
Word up! I also always wanted 722.6 on my b230ft volvo. So that means, that we have the question: which external signals does it need to run properly: engine torque signal, output shaft speed, engine rpm to adjust the lockup, and what next?
The shift speed may be improved but it still looks like theres about 500ms - 1000ms of delay between paddle press and shift completion

How can I order tcu for clk320
I assume this will not work on my 2001 r129 sl500 with EGS51?
It should!
will this wear down the transmission faster?
depends how you use it. If you are using the TCU to get 50-100ms shift times with 400bhp, then yes. But if you want a stock like experience with it, then no you won't wear it down!
@@RANDASH can you explain better, please?
Hello, is this unit for sale? How can I buy? What is the price? I am in the Russian Federation.
Check the video description
Has anyone here purchased this item as yet?
bruh
Do you have rev match downshifting?
