Speedtuningusa Group Buy??????
How many would be interested in a Speedtuning USA group buy???? I know its not Renntech or Kleemana but for the money its worth a shot.. Its a flash only.. They have revised the 55 program so hopefully any short comings that people experienced have be fixed!!!

The graphs are obviously from a German (correction Austrian) test house....does this imply good ol' German engineering in the product?
Anyone had +ve (or -ve) experiences with these products/folks ?
I know a lot of GMC tuners (SUVs and Trucks especially diesels) love their work.
so long and short of it...I'm in if you hurry

Scared me to death....the guy recently who was having nightmares with his. Glad to see Oliver redid the program.....questions then are,
1) Where did he get the original program from and why was it causing havoc on some cars??
2) What did he do to the program to make cars stop having all kinds of problems?
I do have first hand experience with them.....got the Speedtuning ECU mod right before going Kleemann. ECU wasn't bad, car seemed to run okay and I had no major problems. Throttle response was improved but wasn't earth shattering improvement. Only problem was that it ran ultra ultra rich. So rich that when you stomped it, there was some fuel smoke in the rear....when I went to Kleemann, they kinda stared in amazement. I mean it was DUMPING fuel into it and they couldn't figure out why Speedtuning would do that. My air fuel mix was just saturated.
Just to show the difference, Cory went and popped out the ECU and flashed it and put me on the dyno. I don't remember the exact numbers but it was something like 491 for the Speedtuing chip and 516 for the Kleemann chip.
So that is the bottom line....roughly 25hp difference in ECU's but there is improvement over stock with Speedtuning. I would say if you do this thing, just know that you get what you pay for and there have been some guys with problems already. Hopefully the new program works and you have no problems.
Best part is, if you hate it, you can have stealer reflash the ECU for you and you are only out a few hundred bucks. You'll have to do some creative talking, but you can usually get them to do it for you if you play the "it's just acting weird lately" card.
Best of luck.

I know it might not be the "best" but for the money.. It cant hurt .. and like you say.. Its better than nothing and for the price.. I thinking about doing the ASP pulley and the Speedtuning ecu.. If it sucks im only out 1200.00.. and that will be the price of learning.. I know some others have considered this combo.. Does anyone have any follow up to what im thinking of doing??

I too had Speedtunning's ECU a while back and had same exact experience that Jak did. Sent my ECU to Kleemann and they told me the same thing, the thing is dumping fuel.
Heck, my CL55 with Speedtunning ECU and pulley only pulled 440RWHP or something like that.
My Renntech Stage 1 E55 pulled 460RWHP. Now to be fair, the CL55 with pulley, ECU, and headers, Kleemann BTW, pulled a dismal 467RWHP.

From all the info i can gather is that the speed tuning program is designed to be used with a larger pully.. IE the Hennesey or the ASP .. With more boost more air and therefore need the extra fuel.. So I guess i will just do it and see what happens.. I will only be out 1200.00 .. and if it works awesome i will have enough left over for the Eisenmann!!

By replacing factory-sized crank and accessory drive pulleys with a resized pulley, the accessories are slowed, resulting in more horsepower available to drive the rear wheels. MB crank pulley are factory harmonic dampners reworked to ASP specs."
Not sure how much they add.. But they are 17% increase over stock.. They have to be in the same ballpark as all the others.. I guess the biggest variable is going to be the ECU program.

from underdriving accessories (pulley changes) I'm more interested in understanding if this mod really works as :-
1) just an ECU change
2) Pulley and ECU
Its #2 that seems to make most sense if the a/f ratio gets to the high levels described here....so is this just that people are trying ECU programming for solution #2 as solution #1 ? Or is there a real problem with this ECU map for both approaches?
Griffin377 I've been talking to Oliver also - he swears this is old news and that the mods work. If so this is the low cost k1 as far as I can see...and to read that E55_Power's CL55 made only +27 RWBHP more at K2 (with headers) than the Speedtuning (ECU and Pulley) seems to make sense if the speedtuning is really at K1 levels.
Also isn't EVOsport using this same "powerchip" maping - no one talking about over-rich for them?
Q. for JakPro - are you saying that at Kleemann on the way to getting the K1 that without pulley just ECU your E55 made over 516? (I presume this is estimated to be at the crank!!)
That would itself be a good mod for me - just remap to get almost +50 (using stock at 469) - with no other mods, no signs for the stealer to see as "changes"
Does Kleemann simply sell this??
Anyone have a name who I could ask to quote that?

Yes he has revamped his program and does offer pullies.. But im not sure where he is getting them...
