I have my allocation and should be going hard in a few weeks and one option that I am not sure on is the Increased Speed limit.. not sure if it also increases other performance? or if I do a RennTech ecu, that would do the same? Then there is the resale down the road?
thanks for any info and thoughts

 

It’s just a speed delimiter nothing else to it. Purely for bragging rights does nothing else to the engine etc.

I have a lead foot but I get anxious in the G when it gets up to 90 mph. I cannot fathom how crazy it must feel when it’s going above 120 mph!

 

Not that crazy, I have done 140 and it felt absolutely fine and planted, got to it very quick. I have delimiter option.

 

Totally agree - if you have a need for speed, there are other more aerodynamic and lower CG coffins than a G wagon.

 

Does anyone know if the RENNtech ecu overrides the limiter? I have the Renntech in my E63 wagon and it really performs amazingly. I have a call into them to see if on the G63 it removes the limit... then there is the consideration when one day I go to sell it and having that option over the another that does not? Thanks for the input

 

I ordered the speed delimiter, not sure how often I’ll use it. I have a Porsche 991.2 GT3 if I want to go fast.

 

Lol. Like anyone would go 150mph in a G.
save on the option. No one will care if u have it.
and im sure Renntech can remove it if u going with a tune. Its only a software limiter.

 

The Porsche is the prudent choice, and its massive rotors and calipers bring some comfort to the experience.

 

yes agree, not that often on the g63, I’ve done just once. On my 9114S I’ve done 175

 

Doubt it will make a difference with resale. Probably the only things that do are night package and upgraded rims.

With that said even a base G63 with no options will still have strong resale.

 

Well the e63 wagon easily goes north of 150mph ( so I hear ) ... I have a couple of weeks to make all of these option tweaks, a fun process.. right now the increased speed option is not checked. I agree it would be rare to go north of even 125 in the G - just feeling out what all of you chose. Thanks for the input.

 

I added the option to my G63. I figured what's another 1% of the cost at this point! But I'm also the type of person who will think about that option forever if I don't get it.

 

Frankly - I NEVER have my client's order the factory Delimiter Option - for USD$3500 I have them order the RennTech HHT (Handheld Tuner) instead - much more "Bang-For-The-Buck so to speak that way.. Removes Top Speed Limiter and upgrades to RennTech tune.. much better "upgrade"..

 

I spoke to RENNtech this morning and you are right. I have the full ECU on my E63 wagon and it really is a great bang for the buck! night and day difference. I am not ordering the MB delimiter

 

EC can remove the Speed limiter while they do the tune and TCU tune....I'm back in the hunt for a 13-16' Magno to replace ours...

 

There is a 2016 G65 on Bring a Trailer right now (closes later sometime today). 28K miles or so and it's the grey magno color. Good looking truck, and that V12 motor is fantastic. I had the Renntech tune on our 2017 G65 and it was a monster!

 

I wonder when automobiles will transition to the business model of computers. That is, you can buy this piece of hardware that's useless without its operating system and application software. And you have to sign a license agreement acknowledging that you don't own the vehicle's software and you're not permitted to make any changes or modifications to it. If you do, your license is voided and you're left with a useless hardware platform. Of course, this is a small problem compared to the legal jam you'll be in. My guess is that Tesla will lead this transition, mainly because of its apparent leadership in self-driving technology, and the obvious consequences of tampering with this technology by adding aftermarket gadgets and/or behavioral software revisions. Longer term, automobile "ownership" will likely disappear. Like everything else, we'll be able to "subscribe" to an automobile, pay a monthly fee and have access to transportation -- and most probably the automobile will be a different vehicle each time we summon it. But we'll have our choice of a Kia or a Maybach. On the plus side, my garage will transition to a full-size cave with a 6 ft. TV with surround sound, a billiard table and a kegorator equipped wet bar.

 

Glad to see there are others just like me... lol !

 

I was going to get it as well on my build, thinking that it enhanced lower end performance as well. After the reads, it seems I wont need it after all.....

 

Unfortunately this will likely be sooner than later... At least you will be able to enjoy your garage in a different way!

 

Talked with RENNtech again and really there are so many good options that you can go with, from the simple speed limit eliminator that enhances low speed performance as well to engine ECU upgrade giving you roughly 90 hp/ 90 fttq and the best part is that with a simple plugging in the module, you can go to and from stock settings in 60 seconds. Then there is achance I may not even need/want to add this once I have G63 in my hands. - I also ended up ordering the first non white / black or siliver new car ever... I went with China Blue after seeing one in person..

 

Chevrolet tried to retain ownership of software in a vehicle just a few years ago (2015) and was shot down over this.

 

Interesting -- I found a bit more about this at https://www.techdirt.com/articles/20...opyright.shtml including a couple legal briefs filed on both sides of the issue. Intellectual property -- patents and copyrights -- is a deep, complicated and abstract branch of law, and is made more so by the underlying technology. A patent or copyright protects the ownership of the property by outlawing others from reproducing and profiting from it. However, I'm not aware of any law(s) that prevents a person from modifying a patented object to better suit a particular personal use, nor one that prevents a person from modifying copyrighted material for improving its utility for personal use. For example, I once borrowed a text book from a colleague to whom English was a second language. He had written copious translation notes in the margin to improve his comprehension. Did he violate the book's copyright by noting the definition of words in this manner? But had he sold copies of his notated pages to others, he would seem to be getting into a legal gray area. I'm certain there are some legal minds among the members of this forum, and it would be really interesting to hear some opinions on this topic.

 

Which is a better option? Renntech or Eurocharged?

 

I've not used either, but I would say Renntech only because it seems that Mercedes is tolerant of Renntech (and actually some MB dealers are Renntech dealers too), so it would lessen the risk of having any warranty issues.
