I might have to agree. GAD stage 4 turbo upgraded GT63s is only running 10.14@137mph (they claim on 100 octane but that’s likely RON so our equivalent of 95ish). Regardless, that’s not much return on a $35k investment!

it’s the same ECU and they spoof **** over CAN/OBD as well as boost TMAP sensors

dav461

same ECU ?
to give same orders through tmap sensors, these two models must share same turbos, is that what you want to say?

MuffinFlavored

boost is just a number electrically over some wires

dav461

you might be disapointed, but these two cars have nothing in common (even ECU as you mentioned) between two engines, except marking "m177"

MuffinFlavored

they are both bosch med1775 units

dav461

software inside units is different.
even p/n for units are different.
if you get ecu from w205, you have to erase it and clone to your car specific. that's how it works Muffin.

MuffinFlavored

yes but you have to look at it from the context of a JB4

what is a JB4? a $30 PCB from China that is reading input (CAN PIDs like fuel trims, octane level, blah blah blah) and that spoofs input (turbos making 21psi but you report to the ECU they are making 19psi so it overboosts an extra 2psi, I think... maybe, don't wanna spread fake news)

You can run different software numbers for sure, but they are pretty similar and the "tuning" related CAN PIDs surely have to be in the same locations or similar. I know you have a Xentry computer thing, you can monitor all of this with that, then sniff the traffic and make your own JB4.

Do you think I am missing something/confused? I might be. But, from a JB4 perspective... read 5-10 parameters, spoof 5-10 numbers on the fly, pretty similar for 2 MED1775 M177 backed "powertrains"

You're funny.

I’m leaning towards keeping car as is and just changing platforms. I don’t think I want to dump another $5k into the car.

MuffinFlavored

I take it as you think I am grossly oversimplifying what a JB4 or any piggyback device does. I'd be curious to hear what I'm missing. I truly do not believe it is some pinnacle of automatic engineering by any means.

MuffinFlavored

Go high pressure fuel pump and get an E85 map. You would be one of the few/only people in the world running E63S E85 from what I know.

What platform were you considering again? You've said before but I forgot.

dav461

you are missing one simple thing... jb4 is bad.
now imagine spoofing data ( in case with jb4, all parameters are universal, as you said c63 and e63 are same lol) that was configured to do job for one engine to spoof to absolutely different engine hardware, different turbos different compression ratio different max boost (1.2bar for C, 1.3 for E) different gear ratios
well, why i am even surprised, results of jb4 speak for themself. its same as buying universal "racechip" module, which is btw shows same results.
ps you cant beat system so easy as many can think, mercedes new platform seek in tailored tuning.

MuffinFlavored

> different turbos different compression ratio different max boost (1.2bar for C, 1.3 for E) different gear ratios

I'm confused as to why you think it would be difficult for the JB4 (which connects to your OBD/CAN bus) to do some part number/software number detection, detect if it is E63S or C63s, then tweak the general formulas/parameters. It's still doing wildly the same thing. I wish I had the source code so I could prove it...

But it sounds like we agree overall. It's not a device I would put on my car. I had one on my F10 M5 and it left me stranded in traffic. Took it off, 2 weeks later, entire engine blew. I can't prove it was the JB4 but... just not worth it for me.

The same car is now in the 9's

MuffinFlavored

how much of an improvement is that compared to stock, stage 1, and stage 2?

MrkiC63

I run yesterday a stock 2019 E63s station wagon ... soon software 🤪

MrkiC63

Stage 1 / 780hp stock hardware
Stage 2 / 820hp catless downpipes

MuffinFlavored

100-200kp/h pulls:

stock: 7.95s
stage 1 (just software): ?
stage 2 (software + downpipes + filters): ?
stage 3 (software + downpipes + filters + turbos): ?
stage GAD: 5.26s

MrkiC63

I will share the Stage 1 results soon.

MuffinFlavored

33.8% improvement

1% for every $1,000 spent 🤪

MrkiC63

if you are the only one who can perform that times you can ask for it 😊

MuffinFlavored

CPC unlock: $2k

stage 2-3 tune: $2-3k

downpipes + installation: $2k

hybrid turbos + installation: $4k

$10k-ish with no supporting mods to transmission. i wonder how “reliable” this setup would be

MrkiC63

Yes sounds everything so easy but needed lot of development.

Here an other fast W213 E63 Sedan from GAD 😀👌

MuffinFlavored

5.03s is very fast... i wonder it that’s on race fuel.
