Eurocharged 722.9 TCU tune dyno

- Graph explanation of Eurocharged TCU tune of the Mercedes-Benz and Mercedes-AMG 722.9xx transmission. Showing torque gains, shifting time changes, and torque decay changes.
Notice that RPM of shifts does not change, only torque, and time endured to accelerate and shift is reduced.
DISCLAIMER: The test is performed on Dynojet 424xLinx without Eddie Current resistance to simulate wind and friction resistance. Actual gain varies by vehicle weight and road conditions, but this demo shows the decrease in shift time and torque increase based on the dyno roller inertia.

Small gain for such a large amount of money. $2K plus 😳 I will say the ECU tune is fantastic!!
several tenths of second in quarter mile is not a small gain. TCU tune is recommended as next step after ECU is done
Just ordered my TCU tune today. Will do that first, since the 10 year old CLS63 transmission has "old" software. After the tune, I'll consider doing the ECU. Looking forward to better shifts!
TCU tune is not very effective without ECU being tuned first. It also should not be used to speed up a slow shift caused by wear and tear, or be expected to be a replacement for Mercedes software update.
@@EurochargedBoston Thank for the info.
Would you consider making a tune similar to something like the stock Amg-Lite models have (like the C43) with ignition cut on upshift
Contact us at sales@eurochargedboston.com to discuss your request please
Well explained. Thank you. Any comparisons with CPC tuning?
CPC tuning is intended to remove low torque limits imposed by the factory, intended as a hardware safety measure. The two products are not "either or", and the two products should not be compared per say. Any AMG with CPC limits from factory need the CPC tuned in order for it to realize the full benefits of ECU tune.
ALL AMGs can benefit from a TCU tune, regardless of CPC.
Omitting CPC tune in a car that will need it will cause a limp home, and the graph will be a flat line at 0 lol
@@EurochargedBoston Thanks for the clarification! Is the differences in power really noticeable with a CPC tune?
@@Truongy1991 read above, last line
@@EurochargedBoston Also is the TCU tune available for newer model 9-speed transmission?
what about TCU tune 722,6 the upgradet 2007 models, what have there ?
Contact us directly please. contact info in description
Great video! I have the stage 2 ECU tune from Eurocharged-Dallas on my 2018 C43 and it seems like it has issues shifting at low speed when stepping on the gas its almost like something is binding and I have to let off the gas. Would the TCU help with that? The car seems to get confused when shifting at low speed when you step on the gas. I've heard other have this issue as well with the tuned M276.
Please visit our shop in Dallas to evaluate the situation. eliminate the possibility of mechanical issues, make sure you have the latest ECU and TCU software. TCU tune is not intended to repair any issues or improve shift quality.
This is a question for anyone who has a little knowledge, anyways to tune a 722.903 ina diesel v8 to shift a tiny bit faster ??
we can. Send us your vin and details to sales@eurochargedboston.com and we can set you up :)
Any way to tune the 722.9 so it would hold gears in manual mode and it won’t upshift by itself ?
I would bet you can custom do that, or go through BenzNinja. Doing many upgrades with them next week, euro highbeams, auto start/stop off, etc. Edit: will ask
Hi i have a Mercedes e400 w212 m276, i already have a stage 1 going to stage 2 after i put the exhaust and downpipes i wont race my car really, just have fun on the highway every now and then, do you think its worth having the tcu tune done anyway?
Hey man, I have an E400 w212 with Eurocharged stage 1 like you. Have you gone stage 2 yet? If so, how's your car holding up?
@@sb2h not yet, i need to get my downpipes fabricated then put on, last Saturday we put on the cts intercooler, cant wait to install the DPs then upload the stage 2 tune, maybe in another month or so.....
@@DeAssassin345 how was the intercooler install? I'm thinking about installing a better one but staying stage one. My oil temps are about 10 degrees higher than they were stock on average.
@@sb2h it’s awesome, car feels more responsive even on eco mode, I feel like the ecu finally made adjustments for better air flow and she pulls better….
Any chance you can request the tcu limits be disabled entirely?
You can in theory, the transmission will last between 3-4 shifts before it turns its clutches to silver smoothie.
It's shifting way to soon, losing time ET fall off and that's why people saying they are losing .10th in 1/4 mile time, Stay with stock tcu 1000%
The graph is against time, and not rpm. look again at 1:45 and observe how RPM shift point is identical to stock at 6100rpm when graphed against rpm
