What company does the best job (dollar/hp ratio)?

Upsolute

Powerchip

I got a dyno on powechip and compared with Upsolute in my site:

www.paulscrossfire.com

Hope it helps!

 

With all due respect, they are both the same program... They are all the same program...

 

I agree, they are the same! So it comes down to price where as Upsolute will win!

 

Kleemann chip tuning. Guaranteed 15 hp at the crank with dynos. Email them and they will supply you with dynos from a MB SLK. Very nice people.

 

Just got finished reading this thread. Lots of good info here.

Just to confirm, the SRT-6/C32 AMG/SLK32 AMG software that Renntech sells for $1,500 or whatever is the same file that you can get for $250 - $300 at SpeedTuning or Inmotion Tuning USA? That's good to know!

 

Dyno-schmymo...

You can figure actual horsepower simply by knowing the actual weight of the car as tested and plugging in quarter mile E.T/mph figures in to a simple formula. Go to www.dragtimes.com to find out. If you plug in typical times /speeds posted for stock Crossfires and figure a 185 lbs. driver plus the published weight of the car it figures out to 215-225 Horsepower. Just as advertised ! I know 60 foot times can vary but averaged between runs along with the top end speed the "formula" has proven very accurate over time.

I think it's a h*ll of a lot more REAL WORLD than dyno figures. Dynos are good for tweaking A/F ratios and the like but it's really ACCELERATION we're after here !

Go to the strip, make some runs, do your ECU or other upgrade and repeat.

If the car's faster, great, it works and you've spent the money well.

If you run slower you have wasted time and money.

Been there done that...

But that IS the REAL proof !

Slim

p.s. guess I'm spoiled since there are two dragstrips within a 15 minute drive from my house but NOT A SINGLE DYNO...

 

Does Inmotion work.

 

SpeedInnovation is about $600 and is for real. The people there are great to work with and are concerned about your opinion. I can only speak for my experience but man I'm glad I did it, my car kicks a*$... Call the guys at SI. The other ECU people like upsolute may be good also but I can vouch for SI.

 

Here... do your own and do everybody else's.

Can anyone here vouch for this product? I always lift my brows when I see ad's with spelling mistakes!
Sounds like a good product if you know what to change your maps to.

 

the page has spelling mistakes because of the translation. I've yet to hear about any custom relash accessories for the SLK or Crossfire.

 

They're even cheaper on Ebay...

I also found a few guys selling all of the tuning files on CD. These are more than the likely the same files that companies like Upsolute, Speed Tuning USA, Inmotion, Kleeman, and even Renntech are selling for hundreds or even thousands of dollars.

 

It'll work on the Crossfire and SLK. In fact, when you purchase a "chip" from SpeedTuning USA, they actually send you their "flash kit" after you give them a deposit. The flash kit is essentially the KWP2000 cable and "tuning file" specific to your vehicle. That is the same file which comes on the Ebay CDs (along with thousands of other files!).

That's what I'm talkin' 'bout! I've got a Hypertec Power Programmer for my diesel, which is essentially the same thing, though the program is installed in the programmer, and takes all the guess work out of it. Bottom line is - yes, you can do it yourself!
