looking into an ECU tune, wat is a piggy back ECU? is that possible to do on the C36? how much and where should i go to get thid tune? mmaybe in a month i'll be going to do this to my car

2PHAST

A "piggy back ecu" is a a programmable ecu wired between your cars orignal ecu and the car itself, it intercepts signles to/from the ecu and modifies them according to your specific tune.

I have a Unichip "piggy back ecu" in my CLK and it is used to adjust the timing and fuel curve, since I am running higher than normal boost (Kleemann) and larger than normal injectors (C32, 40lb).

I don't know of any specific "piggy back ecu's" made for Mercedes, mine is a generic ecu which Unichip happened to have a wiring schematic for (E240). They may or may not have a wiring schematic for a C36, you would need to check with a Unichip dealer and have them search the Unichip archieve and see what is available.

More info on my install at www.clk32k.com

you are better just getting the SpeedtuningUSA tune for your C36, Oliver can gain just as much from his ECU tune than a piggyback can all without the headaches, plus his ECU tune costs MUCH less.

I think C36 tune is $299 but I can probably put in a good word and get you better price, PM me.

2PHAST

Yes, if a stock performance tune will be good enough for you, then that is a good idea, but if your dealing with unique timing or fuel issues, a pre-configured tune probably wouldn't be suitable. This would apply mainly to forced induction applications.

Powerchip also has a very good tune.

check them out.

powerchip is pricey compared to STUSA

thanks fellas sounds good!

anyway i thought i'd pop this question on here,

when im driving between 60 n 80MPH my car's rpm tends to dip when i tap the gas lightly for it to pick up, it drops 500RPM then bounces back up
it gets annoying i'm not sure why it does this bt when i hit the pedal own harder it just goes, no rpm dip. so like if i'm doing 60mph at 2500 rpms i tap the gas lightly, it goes to 2000 rpm then back up. hte rpm needle would nt stay steady on the gauge it would like would get all shaky if u will...its not as bad as it sounds tho, car hauls *** when you punch it, bt is it a cable maybe? a sensor? anyone have this probelm? already replaced both 02 sensors, i'm running a straight pipe exhaust with a after market magnaflow highflow cat, no muffler and a stock reso. my buddy has the exact same exhaust setup as me and his car doesn not do this. i really hope it's not my tranny. bt doubt the tranny holds the load everyday witht he way i drive it. bt please any help or leads would be REALLY appreciated.

im gonna do you a serious favor and give you first hand knowledge.


powerchip is garbage and they damaged my ecu.. veloce fixed my ecu but offered no gains.


the best company out there to get you some serious HP out of your ecu is MHP. contact Andy his sn is MHP since hes a sponsor on the forums.

also i see ams posting here

your pulley is complete garbage also. since installing my car is losing severe horsepower and MPG is down alot since the past couple months ive had it.

getting that crap taken out tomm and going back to stock.

do not go with powerchip save yourself a huge headache

silence

i'm going to say do nothing and spend the money on repairs

the gains are minimal at best with any "mail order" tune like this (unless you are upping the boost on a fi car)

ohlord

Now I'm really confused.Some kid from Brooklyn that claims he is a financial advisor for citigroup at age 22(when you need a degree and 5 years of business experience as minimum experience just to get hired)Has an export business,owns a restaurant,is an amateur kick boxer,spent $130,000 modding a $22,000 S500
(If you're thinking it's Tommy, it's not remember he crashed his 165mph m104 powered mystery motored E320)
So now the same guy who told me
"Also what are you doing on a w220 forum since you dont even own one"

Is now "gonna do you a serious favor and give you first hand knowledge."
he's asking about sprintboosters and is gonna do you a serious favor with his expertise on ECU tuning?

PM me ZO6 silence is dead on .And the other Guy knows not jack,doesn't back up a deal and probably should practice his own medicine and stick to his own little group

Z06EATER

thanks bro i'll take that into consideration

Z06EATER

so i'm lookin at no sig gains if i go with AMS chip?

ohlord

To require an ECU mod means the engineers left power untapped,and that was not in AMG's book of design.OR you do mods that require the potential to be untapped.Up compression,head work,power adder ,etc.
You may be over scavenged.

300-400 bucks for a questionable 10 H.P. is a joke.
$1400 for a "veloce fixed my ecu but offered no gains" is Thievery.

Z06EATER

ok soo then lets screw that mod lol...i'm just gonna try to improve my intake....also ohlord, u seem to always recc. people to change the trans fluid in our cars if they have high mileage, my tans has 130,000 exactly, i'm thiking of changing the fluid and a tranny flush, good idea? would flushing it be bad?

ohlord

it this way.With average 97 C36 prices dipping into the 7's in some areas and yours being in nice shape.It would be a shame to have to spend almost half the value on a rebuilt trans and labor if the fluid has never been changed.
Mercedes changed their tune on the lifetime fluid deal and even issued a TSB for the same 722.6 transmission in the w211 models to have fluid and filter changed at 39,000 miles.That was along time ago in AMG miles
No flush.You have a drain in the pan and one on the torque converter and fluid at autohausaz.com filter and locking clip for the dip stict tube also.I have a delivered price on the dip stick and diy tips.Also diy on benzworld.org w210 section and mercedesshop.com.
Or have an indie do it,after making sure they just drain and use mb spec fluid.
non spec fluids are playing russian roulette.
The trans will shift smoother,last longer,you will not believe the condition of the old fluid that comes out.
No flush,the 722.6 hates flushing
no linty rags,when cleaning out the pan.The 722.6 hates dirt.

lets see college 4 years with with a major in finance.

currently working for citicorp trust bank/citibank.


are you just so jealous that at 22 i have more then you at 50.

speaking i made a new thread with rules for your ny trip which your scared biach self never posted on.


i have a legal document that needs to be signed by you from my lawyer just incase i paralyze or kill u. pm me your email/ fax pussbag so i can forward this to you asap.

but your too much of a H-0-M-O to do so...

again you have no knowledge on ECU tuning since you cannont afford one so why are you again Trolling another topic you trailer trash.


go back to the navy and suck some Catti sailor homo.

S5LorinserF1

use royal purple atf... i just changed to it and its great.. gears shift much smoother.



lol 22,000 for my s500 maybe so but its still worth more then all of your cars and yuor Trailer Park put together


fudge off stop embarassing yourself with your posts anymore troll

silence

wow, i'm not really a part of this (since you ignored my statement) but-

your sig, avatar and modification choices certainly point to you being the immature one.

are you also suggesting I also can't afford an ECU? for that matter are you suggesting ohlord's car doesn't have an ECU? do you know what an ECU is?

I will say again that the gains from ECU tuning on an otherwise stock (and i certainly include z06s exhaust mods within the stock umbrella) are not worth the $ or effort. He needs to get the vehicle in tip-top working condition and then, if possible, do some significant modifications.

Z06EATER

makes sense! thanks silence!

S5LorinserF1

silence, obv not intended for you

bagelsjustbagel

now now ladies, lets keep focused no fighting please, your both very knowlegdageable and thats alwasy a good thing, different opinions make people who they are

And just dont ECU it Lenny, you should get a Valentine 1 radar detector.

silence

yeah- get a nice radar detector

get some wheels/tires you really like (if you don't already have what you want)

be proud of yourself for having such a cool rare car

wait a while and buy something else (or keep it and plan on dropping HUGE money into it way down the road when you get rich- this is basically my plan)

-drew

Z06EATER

sounds like a plan, for now i'll scew the ECU and juss work on my intake and save some cash

silence

i have a spare aem dri-flow filter laying around new btw- give ya about 25% off ebay prices?

you could use it and reroute some things and make minimal gains at least- but beyond that you don't have any significant mods whatsoever to look forward to cheaply.

Jons95c36amg

My C36 has 103k miles checked the tranny fluid which was reddish. I bought the car at 85k so I think the fluid was changed?
