I agree !

Yep--went straight for the stage 2. Oliver even sent me a personal follow-up email last night asking if I was happy with it--nice customer service. The only downside of this is my gas mileage has gone down. Primarily because I really enjoy stomping the throttle down! this is just plain fun and what I expected from my car in the first place.

For all who just want a little more punch this is probably the best mod for your money. Pull the trigger and do it.

Kevink2,

The throttle lag is pretty much gone. Where I was tromping the pedal to enter traffic last week I find myself having the back off the pedal to keep from going too fast into traffic. Very pleased with this.

Crippled

same exact results here. you took the words right out of my mouth ITCINF

I guess this means the laggy performance was an ecu issue, not the tcu. I'd assume the upgrade includes:

1) remap of pedal motion vs TB opening (a bit like the SB, but better as it is designed for this car)

2) more ign advance at initial take off, and sudden acceleration



Just Curious, for those that might know :

does the shop add a mother or sister board to the ecu circut panel ?

and does this upgrade require the use of higher octane gas, or is 92 pump gas ok?



The only negative is having to send the ecu to their shop, if a dealer visit is pending, under warranty period.

If you can handle that, this is the best bang for the buck!

No other board is added, just a simple reflash.

The dealer has to look for it deep to see and match the file to see if your flashed which they rarely look for.

ltcinf

Absolutely. After flashing the ECU we did a procedure to realign the TB. The stage 2 is meant for 93 octane fuel which is fully available here.

this sounds like exactly what I want to do for my car. and the price is right!
only problem is i can't ship off my ECU each time (from Canada).
guess i will have to hold off until this becomes available here.

thanks for all the feedback and reviews on this, really good info.

Crippled

it wont be available in canada, he doesnt have resellers or want them, he can over night you the ecu back when he gets it!

Crippled

yes you can tune the lag out, but remember when MB builds a car, it has to cater to the whole world who buys the car, not just the members on the board, these cars are more luxury grocery getters or mom type cars (sorry fellas) and most of not all of that crowd will not like the touchy throttle.

If this is true I wonder if it applies to the other CGI models in other parts of the world. Unfortunately here in Hong Kong, MB isn't really MB but more of a franchise and therefore harder to deal with. I'm not even sure how I would go about explaining this to them.

kevink2

As I said in the prior post, normal aligning (rotating) the TB on my Rx7 involved rotating the TB ***'y to set the pedal's idle and WOT positions, making sure the output voltages from the TB were within the specs for each position. There was no power gain for the Rx7, that I can recall. The ecu just used those set points to reflect idle and wide open throttle valve position.

Note the Throttle Position sensor was on the same axis as the throttle valve shaft.

Itcinf , what was the proceedure you guys used to realign the TB ??

I searched around and there is a place in Canada (Toronto) that does the ECU reflashing. Only thing is that it's almost twice the price quoted at $550.00 CAD (and likely will be plus 13% tax like all purchases here in the cold north).

Might actually be a good idea to ship ECU to the US for half the price.

Crippled

turn key off, then back on and let sit with the car acc on but engine off for 2 minutes.

Crippled

i read that correctly, but this thread has nothing to do with the c250's. he said he may be able to get tunes for that car but you would have to contact him.

kevink2

Sorry Crippled, my mistake. ... definate senior moment ... definite senior moment ... definite ...

I'll delete the posts that wandered off topic.

Crippled

No biggie, call him and see if he can hook you up with a tune

ltcinf

Okay--several weeks into the tune and I'm still cracking a smile every time I jump on the throttle. No regrets whatsoever and highly encourage those looking for a great tune for a reasonable price--this is your solution. Off the line and passing and lane jumping in traffic--good stuff!!

So you're the son of a bit**!

same here as well!

ROGER THAT!!!

Ok so I am looking to get a tune. Eurocharged is local but is their a differnce in eurocharged, kleemann and the other tunes?

Knightmare69

The AMG forum seem to have nothing but good things to say about Eurocharged.

Merserybenze

I just got my c300 ECU tuned by speed tuning. Stage 2. Made no difference what so ever! They gave me some line about "it takes 2 weeks for adaptation" (I only use 93 octane). Any truth to this before I ask for my money back?
