RE: Techs to install parts and Tune
Guys, there are a few factory trained and certified techs that do modification to MB AMGs in NoVa, MD- Euromotor Cars- they are the only AMG authorized dealer in the market area and a couple techs at MB of Tysons Corner. Designo Motorsports does alot of exotic modification, but don't have the SDS or XENTRY diag. equipment necessary to monitor the cars after mods, or clear fault codes.... keep in mind that companies that modify ECM data may lock out the MB diag. equipment, and you may end up with various malfunctions throwing in a computer- that should be left for a tune day from a professional company....just my 2 cents

Its hit or miss with them. Sometimes I can reach them and sometimes I cant. It would be nice to know all the details for the tuning day, we are only a little over a week away!

what's the dealio w/ this...if it's on Fri 18th I'll come out and check it out...maybe dyno for a baseline like Clayton...on Sat the 19th I'll be at the AT Speed Motorsports open house and show...I know a lot of you are interested in this also...if that's so maybe let those who plan on going to the show Sat get their LET tunes done on Fri? I'm mainly going to hang out and chill for a min...if I get on the dyno for a baseline cool if not that's cool also...I have LETs stage 1 tune which I can't feel any power difference so it'd be nice to dyno to see if there was any

Couple more weeks would help me to order a pulley, install it and then to do a custom tune. I guess I will have to wait for a next one.

Wait Sunir, I must misunderstood what you wrote, you didn't feel difference with stage 1(pulley,ecu) and stock tune? I am officially won't able to make it Couple more weeks would help me to order a pulley, install it and then to do a custom tune. I guess I will have to wait for a next one.
Couple more weeks would help me to order a pulley, install it and then to do a custom tune. I guess I will have to wait for a next one.I got this done by Tony from LET...he was down here in late May/early June and he flashed my ecu with a file he recieved from Wayne Sustrunk for a stock SL55 I believe....LET can chime in but I'm pretty sure that's what he did.
I drove the car immidiately after as per Tony's instruction that and really didn't feel that much of a difference, I was told that the car needed time to re-learn and to drive it harder so that it would, which I had done during the test-drive. Regardless I did just that the following few weeks; plus I took the car onto a racing circuit at VIR since I instruct track/driving events for MBCA GWS chapter and they had an event mid June...so I was full throttle on a race track which you can't get a better environment for adaptive ECU...still, even till this day I don't really feel a difference?

No I just have their Stage 1 flash for stock parameters... not a pulley with tune

Did you run your SL55 ar VIR previously? If so, did you turn better lap times after the LET tune?

I've driven the SL55 on closed circuits in stock configuration, VIR being one of those, in fact one of my students had a stock e55 there at that event.
I know what the car should be doing coming up to the braking zone on both straights and how to gauge by feeling how the car pulls through the powerband in certain sections of the track with a certain index or landmark (i,e. under the bridge and entry speed onto the uphill esses, oak tree corner exit to markers 2 and 3 at the braking zone, corner exit onto the front straight and terminal speed & rpm at the end of that straight approaching Turn 1). Ironicly I could feel nor observe any difference with my car and the stock SL55 in any of these measures.
I perhaps should have done a before and after dyno when I got the flash done; but I was not comfortable with the dyno that they had at that event; non-load bearing, mobile tow behind configuration, etc...ideally I'd like an in-ground eddy current mustang dyno for measurements

Me too. I mean, thing thing feels fast...real fast. But look what I have to measure it against. A tuned E500 and an R500. I mean...c'mon.
I just wanna make sure it's healthy before I start doing anything to it. Even an unhealthy V12TT is gonna feel fast compared to the other cars I own.

I have no idea It would be good to know though. Its just one week away and there are no details at all
What's wrong with a dynodynamics? Unfortunately I dont choose when/where the tuning gets done. Otherwise I wouldn't have been waiting however many months its been to get a tune!

Mustang dynos are great for tuning...most race cars and teams use this for calibrations to things like Stack or Motec engine managment systems. For incremental rpm/AFR tuning for an ECU in this case a custom tune this type of dyno is the one I've seen most competition vehicles using.
just my $.02 fwiw

Looks like LET/Eurocharged might need to bring out that fancy new V12TT tune they have for my car.
Damn you Wayne/Jerry! I didn't want to spend anymore before Spring!
