You guys make me laugh, but then I want to cry... place
Yes - I have MANY dyno's from testing we have conducted since 1997 on the Boxster (we have been tuning Porsche since 1991). In addition, my own car has been a test mule, as has a software engineers new Cayman.
I must say however, that anyone wanting to see dyno runs (ie. squiggly lines on some paper) instead of listening to actual objective driving perceptions clearly misses the main benefit of software tuning - improved overall driveability!
We aren't only adjusting the WOT power, but part throttle as well as reducing the time delay from the drivers foot into the engine.
IMO MNBoxster is being a little irrational with his comment:
"If you add Intake, Exhaust and Cams, then it's a whole different story, and different engine. But, absent this, aftermarket chips can't hope to gain more than 10HP. You can alter the curves, change the Power Bands, but for the most part, it's not usually worth the money invested, or the reliability lost...
Happy Motoring!... Jim'99"
What he is implying, is that the 'Performance Software Industry' as a whole is fraudulent! In 2006, SEMA estimated that engine control software tuning (ECU tuning) as an industry produces over $1Bn per annum.
I can also show literally thousands of customers that HAVE NOT taken us up on our generous 14-day trial. Once a client feels the extra performance, they are reluctant to take it out - especially considering it is less than $1,000 in the first place.
It is true that in general there is not as much performance to be gained on a NASP vehicle than there is with forced induction - but I am not sure that you are truly in a position to preach what is to be considered 'worth the money' for others.
BUT - the best post Jim'99 was this one:
"These Optimal Points for Fuel Timing and Spark differ throughout both the RPM and Load Range and are independent of each other. This means you don't always want them as close together as possible, contrary to what you've been told. They have been determined experimentally in the Lab and are programmed as code into the ECU (DME in Porsche Parlance) and are called Maps. Using the signals from various sensors in the engine and car, the DME compares actual conditions to a set of known conditions and selects the correct Map programmed for those conditions and energizes the Fuel Injector and Spark Plug accordingly."
... I now can see that you have little idea about how OBD-2 compliant vehicles are designed and developed by the manufacturer, and furthermore, that you know almost nothing about how a software engineer goes about making changes to the manufacturers settings - to improve overall driveability. No offence, but your posts possess the factual relevancy of 5th Grade science report.
The fact of the matter is that our equipment gives us full control over many functions of the engine. These functions allow us to take advantage of high octane gasoline and optimize the engines response time. In the same way that a customer goes and spends $15,000 on the X51 package at the dealership - only to get a chip and intake - there is little difference to what we offer our clients (only at a fraction of the cost).
Bavarian, please feel free to keep on testing it out to make sure your happy. If you are not, then just give us a call and we can put you back to stock.
PS. attached is customers car we are currently tuning! I am trying to get him to join 987board.com
Enjoy the drive!
