Et30 I am very familiar with brian and steve. Do you know mike t.'s jetta, the one that broke brians record. C&M in nyc are my mechanics, both are boost nuts. I would love to have them do something, just have to find the money.

yea i know who mike and chris are, yea i think if i do this to my c43 its gonna take a good chunk of money to make it happen.

e30t387

yea defenatly if i can get any, i know some kid that still has his, i know last year he put down 670whp on the single turbo setup, it was fast, i dont know if its still running .

has anyone successfully installed a standalone or true "full" piggyback on one of our cars?

I know it "will" work, but without the "how" part it's pretty useless.

i'm very interested

.........no one has done it. Don't believe the hype.

ProjectC55

Not tru Ted. My friend has a Motronic Standalone ECU installed in his TT C36. Make that two of my friends.

Ted Baldwin

.........yea but that is not the issue. Mercedes started using CANBUS in 1999. Doing stand alone or piggy back engine management in a non-CANBUS 1996 C36 is no different from what has been done in Camaro's etc. To do so in a modern Mercedes with CANBUS you need a CANBUS adapter. There is a lot of hot air on this topic. Again no one has done this in a CANBUS equiped Mercedes. It can be done. You need a CANBUS adapter probably. I currently have a working CANBUS adapter in my W210 E55. Next step is to try an engine management system. I know that some have argued that you do not need a CANBUS adapter, but they are probably talking about older MB's like the C36 you mentioned.

..........Kleemann has something similar in their ML63TT. Their's is a stand alone unit. This however is boost limited to 0.7bar.

so if i want to swap superchargers, build the motor and run 12 psi (and i win the lottery) what's my next step?

Ted Baldwin

.......if you want to run 12PSI of boost, your immediate problem is not engine management. Your immediate problem is compression ratio. You would first have to rebuilt your engines internals to handle the boost, plus you would need to have custom made low compression pistons. No for the faint hearted. With low enough compression and reinforced engine internals, you might be able to get away with boost sensitive fuel pressor regulators and larger injectors. This is exactly what I have done currently. I do not know if my car is any faster but I am running 8.5:1 CR, 12Lbs of boost and stock Kleemann ECU tune. Like I said earlier, I do have a CANBUS adapter in case a stand alone engine management becomes neccessary. I did all this to go the TT route, but I simply love my car as it is right now.

Ted

silence

ya, i understand all the other work involved.

I'm just stating the hypothetical situation where i simply can't not have full tuning capability and have it run safely- then what?

cicbenz

What the hell is CANBUS?

Ted Baldwin

..........best way to describe is a wireless module to module communication in the car. The traditional wires that things like remote car starters and engine mnagement units hook up to do not exist. You first need to convert the wireless to a wired system.......hence CANBUS adapter.

Ted

Ted Baldwin

...........that is exactly why non one has done this. The engine management in a CNBUS equiped Mercedes needs to be resolved first. I don't think this is impossible. I'm just suprised at people who don't recognize the problem. Anyone can stuff a turbo in a car....big deal!

Ted

silence

yeah, that's definitely true.

Here's to hoping my psc1-003 is flexible enough for the power numbers i feel safe running with a "stock" motor

solo36

i don't think it's all about stuffing a turbo in the car !
It's about installing the turbo and having everything function like facory
but have the dyno numbers high...........

silence

yes, but what we're saying is---

it's easy to get it in there and plumb things up/hard to get it to run right since we haven't cracked the computer...

ECTurboGSX

Its a Bosch unit and there should be software out there that can allow you to adjust the fuel maps and timing maps. The various aftermarket tuners are doing it, they just aren't sharing the secret.

silence

yea, totally agree with you.

However, despite all the stuff i've done to the car in the year i've owned it- i don't have infinite deep pockets. Anything that is done to the car needs to be done by me, and often done using used parts etc. or else it isn't going to happen.

Therefore, until someone shares the info of what will work I can't outlay the funding to make it happen.

svt ricco

try to contact nitrogenbalance...i think his hps gen1 works just fine

silence

it isn't an issue of hps gen I running "just fine"

I'm talking stage II or stage III type "hps gen I kit"

ECTurboGSX

I know that I've seen a few 202s with an SAFC. They basically modify the signal from the MAF and trick the ECU into adjusting the injector impulse so that you can run larger injectors.

Ted Baldwin

..........i believe what you said. With moderate boost, you can probably just do a boost sensitive fuel pressure regulator and the ECU will adapt. There are several types of so called engine management systems. The one you mentioned manages just fuel and is the least complicated. For someone that wants to do 12Lbs of boost or intall a TT system, you need to also control timming. This is where it gets complicated.

Ted

silence

yeah-

i'm running fmu and splitsecond psc1-003 (splitsecond piece is half installed, will know if it works more tonight)

i have no timing adjustment and can only modify fuel trim in closed loop

Ted Baldwin

...........good luck with it. You seem to be the only one in the thread that has understood the issues involved. They are probably ultimately soveable, but not if we refuse to acknowledge they exist. There is too much hype on this topic, but not a single solution. This is probably why a solution has not been found. Everyone wants to ignore that CANBUS exists.

Ted

NitrogenBalance

Oh I understand it too Ted, I also don't understand why it comes up so much like you stated. I personally am little help in this department so I'm just waiting for someone to finally do it also. My system is exactly as stated, 5psi with a split second clamp @ 4.89 and a rising rate FMU. Caveman setup but works and I have no other choice at the moment...

Drew, I would search GregC posts as he used the adjustable split second unit with much success. You will be able to pull timing where my system runs probably close to full timing and relies on the knock sensors..which is ghetto and not good. 1 of the many reasons I don't/can't drive my car in hot summer. I'm curious to your outcome as I will need to upgrade to this unit if I want to add a 1lb or 2 of boost.

For now I would also look into a good H20/meth injection to act as another bandaide tunning device. Solid cheap insurance. Get one with alot of brains and you can set inputs off of IAT's, boost, MAF, RPM, pretty much any signal. check out coolingmist
