Incredible, and with a worse 60ft time to boot! Nice job! it def liked the better air. Seriously wish id joined the TCU tuning party in NY!

try m3

Nice this is great news and a huge step forward on this platform! Can the tcu tune be programmed remotely? I just ordered some r888r and would love to get the tcu tuned lol.

Winner winner chicken dinner... all hail the current stock turbo king...
I said all along tune only we could hit 10.7 @ 130. Its great to see it come to fruition.

Please dump your 0-60, 1/8 mile, 1/4 mile and 60-130 onto draggy!

I see you are stilling spinning into second gear... time to get better tires I think...

I have one question regarding the TCU tune:

With our ECU tunes, for those of us that went with a cloned 2nd ECU to save our warranties, we have the option of swapping out ECU's very quickly.

Obviously we can't do this easily with the TCU. I gotta believe that the dealer can detect the modified TCU? So if you still have a ELW you could be in trouble if car goes to the dealer. Mine does not expire until 1/22.

Just curious if TCU tune = no more warranty, or only for those with expired warranties.

PeterUbers

or can tcu be tuned via obd?

I’d like to see how first gear will hold up after the TCU tune. Any idea how much torque was increased in first and second?

BCP

Not too far, and it would be great to meet up with some of you guys in addition to TCU tuning. Please keep me in the loop -- definitely interested.

​​​​​Using that analogy, it would mean Mercedes-Benz tuned and ran the crap out of the m157 at 518 horsepower circa 2012. So this was the max the m157 could handle.
But then in 2014 the horsepower level was raised to 550 and then 577 on the s models. Does that mean Mercedes rebuilds the engine entirely to handle the extra 50 to 60 horsepower? I think we know the answer to that

I’m sure there is a complex choreography going on. They might have jacked the stated HP on the P30 and S variants but what was the dyno actually showing? And perhaps they put more aggressive TCU protections in place to compensate for more HP. A lot of the changes they make could be for Car and Driver subscribers. Marketing geniuses.

Getting better quicker shifts. It’s playing a major roll

brutus_tx

Are you still launching at 1500 rpm?

Am I seeing over 2G on launch? Damn Son...

Cifdig

Yes. Trying to keep spin to a minimum. If I can get a hard clean start I’m confident I can hit low 10.7

brutus_tx

don't sell yourself short... shoot for 10.6 on a prepped track. If you are pulling 1.7 60fts, and launching over 2 G's while feathering at 1500rpm... imagine launching at 3K on a prepped track...

Cifdig

never thought we would be having this convo of these times for this platform a year ago [img]blob:https://mbworld.org/8aa843ad-e3f1-47d7-8164-1bab776c1a6b[/img]

Cifdig - incredible what you’ve accomplished with your tune journey and thanks for sharing your knowledge which is so appreciated.

I’m curious, does Race start work with your tune? If so what kind of launch do you See with RS out of curiosity?

Cifdig

a lot of spin. Once I get tires that have more grip I’ll try race start again but brake boosting seems to work best at the moment and suspension on soft.

np I always share what I have done. That way we can all enjoy this platform

rjpacman

any change you could take of video of a run? Being on the west coast ill end up being late to the game.

PeterUbers

So cifdig- what are your official mods now?

just tcu tune and ecu tune?

thanks for all your contributions!!

Breaking parts gets expensive as you know. Some have deep pockets and will spend whatever it takes to beat their PB, while others just want a little more to scratch that itch. You need both to fully support the aftermarket R&D, so to dismiss the “keep the HP safe” crowd is cutting off your nose to spite your face. I’m 100% for those willing to take chances and spend a ton for the benefit of the community. Just like I’m grateful for the guys that buy E63’s new so us broke-azzes can buy them at a huge discount 3 years later!

brutus_tx

LOL... we're kindred spirits it seems... I can't bring myself to buy new. I'm somewhere in the middle with all this though with respect to the aftermarket. I want to push the boundaries of the existing hardware and to dip into the safety margins of the mechanical hardware.
I operate within this space professionally in the subsea engineering field. We build safety margins into everything we do. Heck API mandates we test to 50% over design to ensure the unit is fit for purpose.

If MB AMG is going to build a high performance vehicle and equip it with a bumper to bumper warranty, you can rest assured they've built sufficient design safety margin into the components. To get TUV certification they must adhere to similar design criteria as well.
This is the world I come from and which formulates my thinking behind the development on my car. I don't buy hardware for the sake of hardware... 9 times out of 10, the people telling me I need hardware are the people who sell the hardware.

I realize that the OEM components are built to withstand much more stress than Joe Public puts on his car daily. I'm trying to shed light on where the performance boundaries for this car actually are by operating with the stock hardware.

My experiences with the E50 tune aside, we have been delving into the TCU tuner world. The tune that Efrain is running, arguably from all the investigations and talk with people in the know, is considered the safest TCU tune available on the market.
It still operates within the hardware envelop of the existing transmission components and caps the available torque below the limits of the MCT transmission hardware.
This should be considered a stage 1 TCU tune, as it doesn't require additional hardware modifications to the transmission.

There are other TCU tunes out there, and some people are running TCU tunes with zero torque management. When running these tunes you will quickly find that axles are the weak link...

I can't wait to install this TCU tune on my car. Am I exposing it to risk? Of course; but I do that daily running E50 as well.
I have confidence in the tuning ability of this TCU tune provider and the shear library of successful tunes under his belt.

It would be nice for someone to release this as a Port flash. It's kinda a pain to have to get the car where TCU tunes are available. Unlike a custom dyno tune, theres no real reason to have the tuner " on site " for a TCU flash as they are not tailored to the specific car.

NoVAe63s

Just raced a bike out on Lee Hwy, goddamit needed a few more horses to pull away! But surprised the hell out of the rider.

Maybe I need to jump in on the TCU tune group buy!

NoVAe63s

When I took my DSM from 195hp (keep in mind this was a 1991) to 240, the clutch couldn’t hold. Then at 276 I snapped a rear axle. Then the turbo started roasting at 18psi etc. etc.

That’s sort of my hesitation here, the DSM drivetrain failed at 20% and then at 40%. Yes we’re not talking about an E63 which probably has a lot more over engineering in it - hopefully it is 50%. And I have no problem swapping out some relatively inexpensive parts to match the new output, but I’d prefer not to rebuild a transmission or change the character on what is my DD.

I’m as excited as everyone else is, hopefully the skepticism isn’t received as being a doubter. Everyone has their levels of risk aversion and mine is probably on the lowest end.

I share the same view, very well said..

When i visited the AMG engine factory 2 months ago, in the engine test room, the engineer told me they ran the M157 AT REDLINE, non stop, 24 hrs a day, for 3 weeks during testing on the engine test bench... These types of things really put a smile on my face to geek out on!

Cifdig

I wanna stop but it’s so hard too when the times get better and better stock turbos!!!! Stock intake
