Who make does and how much and what gains

Sincity

Went to the site and that is some high-quality work. Let's stay on topic. I'd suggest you start a new exhaust thread otherwise this will get lost inside this thread.

It doesn’t matter if it gets lost in this thread. The photo is not about the exhaust, it was in reference to the comment that MHP are the only ones who make LT Headers. Maybe I should have been a bit clearer about it. Aussies have the same problem you are discussing, why are tunes so expensive along with cold air intakes, exhausts and other mods for C63’s. The fellow who R&D’d this exhaust is one of the most respected LSx tuner’s and mod shops in Australia. He also happens to be a Merc fanatic. His solution to the ridiculous costs part suppliers ask for their mods, was to design, supply and fit his own at a sane price. Same with his in house tunes for the C63 and other MBs, he doesn’t flash tune, he throws them on the dyno and goes from there. The power increase is good, the torque phenomenal. Apart from being a mechanic he’s also a former IT man and a quiet member of this forum. Sorry to intrude.

that is some nice work. if we here at mbworld would of have seen this before i would of not said MHP is the only ones that have longtubes.

so spill the beans who's product is it.

I will take a pair if they're cheaper than what's available from MHP or evosport, those look awesome.

Bob from Renntech and the distributer in Taiwan.

The price is $120,000NTD(around $3,750USD) in Taiwan.

Sincity

NP. Your contribution is most welcomed.

Could you please ask him what he did with the Torque Limiting map? Did he have a chance to look at the E63 Torque Limiting map and go from there? Tks.

Sincity

I wished GIAC would get involved with C63 tuning. Emailed them and no plans at the moment.

GIAC is great, that Flash tool you posted is awesome, tuned map, stock map, even valet map all at the finger tips.

mthis

whats true

i know my friend asked for the rat and they told him no. is renntech hiding this from us here in the u.s

jangy

The aussies led the way for the E55s as well.

jjb03

Told not toled.
That is all.

soldier2304

That's sick work. More info on this please!

RNS-11Z

im hoping to order that exhaust from sonny next yr.

its true though, you guys in the us are getting screwed for everything.

those one peice wheels for eg, i got quoted 4500 us for 19s, one piece. for approx 3k us im getting 3 piece wheels from japan made which also includes shipping. my tune costed me under 2k us with phenominal gains.

hooleyboy

The RAT is not for the 63's The 63's have "The Brick"

RAT=55's
Brick=63's

They work in the same way basically, but since the ECU on the 63's is much different than a 55s they have to have two units. Will Renntech end up calling "The Brick" "The RAT" at some point is yet to be known. Either way who ever is naming things over at Renntech needs to do a better job..lol.

There is no doubt, having the ability to switch files at home is great.

As a software engineer ill chime in here... Sincity I think your looking at the whole ECU tuning development costs in the wrong way.

The actual "maps" are the easy part of this whole process (in relative terms that is). What most of the companies are spending most of their time/cost is cracking/de-assembling the ECU in order to figure out how to get the new map on there. This type of reverse engineering takes a LOT of time/cost, and if im not mistaking the C63 ECU has not been fully cracked yet either (they can only change a few of the parameters).


With that being said I do agree with you, 2-3 k for a tune that essentially removes the factory detune is a little overboard.

mthis

what where your gains.

Sincity

Kleemann is not as bad @ $1400 and supposedley LET has a tune for less than that.

Are you referring to programming through the OBD-II port? I hear that has xx bit encryption and is difficult. How about flashing through the ECU plug? Also, aren't other tuners cracking open the ECU and using "fingers" (referring to usage in video game console mod chips-not sure of actual name) and reading/flashing off the chip? This whole thing is still a mystery to me and I am getting bits and pieces of information.

Sincity

I was browsing the BS forum and came across a thread mentioning that a company called Asura Desgins has a C63 tune. Has anyone ever heard of them? http://www.asurades********/tuning.html

Merc63

Renntech doesn't crack the ECU open. It remains in tack like you sent it to them.

Simply call renntech and ask them why the price is so high. Im sure they will explain what is involved in cracking and programming the ecu.



AUSTRALIA GUY: Can we purchase that exhaust and have it shipped to Canada?? That is beautiful.

Sincity

LET will soon be able to program through the ECU port. How does Kleemann do it?

Just called Asura Design at their 714 area code # and it forwards to a 408 cell (presumably). No answer....????

c32AMG-DTM

By ECU, do you mean OBDII? Just clarifying. Also, you say "soon" - but LET's already been tuning 63's - so did they crack those ones open, but are changing processes "soon"?

AFAIK, Kleemann, Renntech, MHP, etc., all currently open the physical ECU box to flash their proprietary tuning for their C63 customers. I've been wrong before, however.

Sincity

No. Jerry says programming through the ECU port itself; not OBDII. You send him your ECU and he plugs it into his hardware for the flash. He mentioned he doesn't have to crack the epoxy. Or, he can also do a dyno tune.

c32AMG-DTM

Ah, okay - cool info, thanks Sincity. Dyno tune would have to be OBDII (I think?) ... so I guess that would mean both options exist.

jangy

How without going OBDII?
