Looking forward to the long term reviews ... 6 month, 12 month

can this tcu be done remotely?

Look in this space for an update on a TCU tune only E63S running stock ECU.
Having looked at the data, I'm starting to think a TCU tune is the biggest bang for buck for daily driving, then followed by a ECU tune for improved ET's at the track.
Whats even better is the fact the TCU tune is completely transparent... it doesn't get flagged in the ME. This should help alleviate some concerns for people still rocking warranties...

Brutus - hey totally agree and another appeal of the TCU tune is if you blow up the trans its maybe $6-8k to replace compared to the motor at $25k from an ECU tune gone bad.... so to me the TCU seems like a no brainer!!! Are they coming to Chicago/Milwaukee area anytime soon to do a group TCU session? Think we could get 10+ for sure in Chicago to step up and do the TCU.

I'm waiting on a RWD version that is streetable in the first couple gears.

That can all be managed in your tune, and by your right foot We can tune for whatever you want - but doesn't really make sense to leave the tq limits low... Just get a tire on the car and you'll be fine

Thanks!

Im in for that Chicago tune! I'd like to see how this compares to the RennTech "TCU tune" .

billvp218

what are the stock default torque limitations by gear for the rwd m157?

DavesMeanE's

There's a lot of interest coming out of Chicago! Y'all need to just go to the website and sign up! If you're "In" just put down the deposit, you literally have nothing to loose, as it will be refunded if we don't end up making it. The only way we will make the trip is if we have the roster filled

Chicago session will be in Addison, at Pinnacle Motorwerks Form for that location is live on the website, so go sign up.

Nothing for the north east region?

DavesMeanE's

Most of the Northeast is gonna be handled by @5soko - Get in tough with him and I think he can work it out with you

Thanks!

Can someone please explain what is happening on the 2-3 gear change in the video posted in the link above? There is like a swing of 500 rpm after the shift. Someone mentioned boost limitation because of a lack of a DV or blow off. Thanks!

brutus_tx

That video was graciously provided by Cifdig the weekend following his TCU tune.
We all saw and commented on the video. There were a couple of ideas thrown about. Another idea was wheel spin may have caused it.
Truth is we don't know.

I defer to Cifdig to answer with his experiences post TCU tune. He's probably done 20 launches or more if his draggy activity is any indication. .

Hopefully he can come into the thread to provide some insight.

Here is another Ridealong from in CIFDIG car from a fellow memebrs first time in a TCU tuned car

Tq limits can be set to your desire and tailor made to your wishes per gear as mentioned by Dave

Without muddying this thread... here's a link to a EC ATX world record pass of a stock turbo W212 2014 E63S...
It benefited greatly from a TCU tune and an Ethanol E70 Tune....

we need a Bay Area - N CA day to be put on the books - who's in?

For resale lookup, how would one verify if the TCU tune has already been applied in a used vehicle?

brutus_tx

I suspect the only way to tell without having access to the original flash hardware would be to log a data run and compare throttle closure against full throttle request in the lower gears.
Stock turned TCU's will show throttle closure to restrict boost in the lower gears. Modified TCU's running this tune will allow for full boost in the lower gears. 5soko created a post around this....

maxknuckles

That's two of us

I can't wait!

OMAHA NEBRASKA just added to the list of cities/regions to get the TCU tune.
SLM Auto Care...sign up here

It doesn't get any more centrally located than this.

Nebraska, Kansas, Iowa, Missouri, Oklahoma, and Colorado... Its a team sport, and I need your help.

5soko

I know this thread and many others have gone off topic, but as mentioned, doing a quick datalog of a 1-2 gear pull would clearly show, unless the customer opted for a low tq limit tcu tune below that of stage 1, would need more a good eye to see. Same
goes for most tune only ecu tunes out there for resale.
Many dont know their used car is tuned until they either datalog or they opt for a new tune, and this case, if your car is hooked up for a TCU tune, the tuner would be able to see it has been applied and save you the trouble

I'm in $300 for tcu with Jvakos and others

Anyway this can be done remotely?

brutus_tx

not currently... where are you located?
