Seems Sprint now calls their new version auto as it is a toned down version and works with all newer models of MB. The old/manual version causes newer MBs (06+) to kick in the check engine light or into limp mode as one member has said. I use a old/manual version with no problems and it is actually much more sensitive than the auto/new version but my car uses an older ECU setup (altho as said it is not an ECU mod, the speed of the fuel feed does affect the ECU's interpretation of the car's health, hence sends the newer ones into limp mode or the check engine light lights up) and has less CC's. There is actually a 3rd version specifically for the W221 S's as the ECU is different again.
2. booster's location
I have personally installed them on my buddies' R171s and and regular W203's and they are under the dash - I think also the same on a W211 E55 I saw being installed. On mine and a W210 E55, it is in the engine bay - 2 minute plug and play. I presume the C32/C55's might be a bit different but haven't checked - if you guys have confirmed it to be on the pedal, then it is.
My apologies for the confusion.

Just following up again as promised.
I've used the thing for a few hundred miles now in mixed mode city/highway and in various driving styles. I'm still a big fan and I suggest it, that hasn't changed. However, I have decided that the reset trick still needs to be performed periodically to maintain sharp and consistent throttle response in our drive-by-wire cars. It took the car a lot longer to "learn" how to be slightly softer around the edges than before the Sprint Booster install, but I was able to discern a difference. I'd say that before it was necessary to perform a reset every few days of normal driving. Now I'd say the interval can be more than a week. Your experience will vary based upon how you use your car - I think I'm too gentle/non-aggressive in my normal driving, since I use it for my daily, mostly highway commute in the Summer months. This tends to give the computer a lot of "I want to take it easy" kind of information. If your drive to work is a blast through canyons daily, you might NEVER have to perform the reset again after you install one of these
Also, I can report that the car is not too touchy after performing a reset with the Sprint Booster installed. I guess there is only so much slack to be cut out of the DBW system.
One last thing I have noticed: If you go from light throttle to WOT at a speed that would require a two-gear downshift of the transmission, the pause until WOT is delivered is not shortened from stock. The ECU still has to decide how many gears down you want, etc. - Sprint Booster does not help there. too bad there's no GIAC-style chip for our transmissions, like in Audi S4's!

Wow, you took the words right out of my mouth. I was about to post something similar today.

AMGSC and Tump43 (and I guess all others who want in on this group buy). To get more info, and to give him your info, he asked that you please email him at: mmz-timelord@sbcglobal.net
He said he will add you to the list, he's just waiting for you to drop him a line with your info. That is also his paypal email if thats how you wish to pay.

There is no snake-oil salesman lurking about here
Second, the install. It is exactly as jgsx said, and like the photos boohooramblers posted. Took all of 10 minutes, and I saw immediate improvement. The car really does behave much more like it has a mechanical linkage throttle now, though if you drive in many varied traffic types you will still be able to detect some non-linearity. It feels as if they wired a logarithmic-scale potentiometer in series between the pedal and ECU, such that the phase of the stock dampening effect and the phase of the fix cancel each other out. The result is a decidedly more linear feel. You could theoretically get similar effects by modifying how you use your gas pedal normally - but it would be bizzarre because you would have to stab at the throttle fast and to exactly the appropriate percentage of travel every time. Good luck developing that kind of precise leg and foot muscle control!
My favorite thing about this mod: the "D" (auto) mode of the transmission is finally usable! After a long tiring day at work, I can now leave the car in auto and use the gas pedal alone to call up throttle and downshifts exactly appropriate for the amount of pedal travel, instead of (1) guessing, (2) waiting, and/or (3) just using manual mode to ensure that it downshifted the right number of gears. How many times have you been cruising along in traffic at say 45-55 MPH, and needed a single downshift + some throttle to get into a briefly-open hole in traffic? Before, if your car was in "D", you would press the pedal and get almost nothing. Then, you'd press harder and even if you were smooth you were gambling that the car would not just go two gears down and give you more than you asked for. I'm not some kid in a Civic with a giant wing on the back
- I want smoothness AND responsiveness, without getting all out of shape and embarrassing myself and/or scaring other motorists. The only reliable solution before was to call up a downshift manually via +/- mode, then press the gas at just the right moment to accellerate smoothly, then upshift to "D" again when the traffic move was complete. With the Sprint Booster installed, I just press the gas about as much as I THINK I should to go a little faster, and presto! The thing does as I ask instead of "Oh, you want to go faster? Umm.... how about NOW - ZOOOM!". Also, I don't get caught in auto mode with my pants down by quick cars who want to show me something. Nail it a little, nail it a lot - you get whatever you ask for.
Oh - and yeah, you can chirp the tires in 1st and second if you like
Finally, I deliberately did not perform the throttle/trans ECU reset trick when I installed the Sprint Booster. I want to know if it will provide most/all of the reset benefits, without requiring resets all of the time. I had been in the habit of doing resets almost daily before. So far, it is working great, and I'll wait for a while before trying a reset to see if it is good enough alone, or if the tranny will "learn it's way around it". I have a feeling it will be fine, because what the transmission is now learning is throttle inputs that more closely resemble those I actually desire! I also want to see if it becomes too touchy after a reset now. I'll follow up later as I learn more.

Both, actually
The first pic is how it looks out of the box. The second (set of pics, actually) show the install as if the module did not have it's harness connected. That's just for clarity, I assume. Written another way, pic #2 shows how to install what is in pic #1.

The first pic is what an MB one looks like.
