simple mods for a rookie pt 2: ECU software and sport chrono
Since I can't reply yet I thought I'd reply this way for now.
Thanks dndodd and MCLC26 for your responses. One question - my car has the sport chrono pkg and wondering what are the positive/negatives of adding the ECU software? Or is it basically the same thing? |
The sport chrono can be worked into the ECU upgrade format . The technician will know as soon as he sees it.

Or is it basically the same thing? The sport button still works like before. I just don't use it. I think I have tried it once since the upgrades. I like the non-sport mode profile better especially with the upgrades I have made. |

my hunch is the ecu flash does the same thing as the sport mode..increases throtte response - tricks people to think they are getting more hp
|
The Sport button does more than that. It stiffens the clutch engagement. That with the PASM make the car just more aggressive. Big difference in my opinion

You missed the magic part the Plenum!!!hilarioushilarious
In all seriousness the plenum made a difference in my car. But I wouldn't give up any of the mods I have made. |
you are right - i did not have the plenum...could the plenum really add 25hp? surely porsche would have figured this out? i mean in todays world of more hp = better car im sure porsche would have saved money by simply putting in the plenum in their S cars rather than using a 3.8 liter engine instead of the 3.6 L...im no engineer..i can only give you my first hand experience...giac + evo intake and headers = zero additonal power...i dynoed my care before and after on the same dyno...i also dynoed again on a different dyno..still no power...the after dynos on the 2 different machines were almost identical.....

Don't forget that Porsche still needs to consider things like gas mileage for marketing purposes... I'm sure they were aware of the possibility of increased performance but they may have decided that a more efficient exhaust system and plenum providing an additional 30-40 hp wasn't worth the loss of fuel economy... also consider the additional revenue coming from performance upgrades... all p-car buyers are not hp junkies like us... |

The engineers at Porsche could higher numbers from the engines if they wanted to .. but then it would cross into their other model-markets. |
