Edit.
It's a long story but I have just fitted a switch pack from a 997.1 GT3 which Doesn't have the now obsolete spoiler button but it does have the Sport button. I have examined the circuit board and cross referenced it with the wiring diagram (kindly supplied by an awesome forum member) and now that I fully understand the switch pack, it seems that my car is pre-wired with the correct Yellow with Yellow trace wire that signals sport mode to the initial ECU that would link to the DME. It seems that my cars DME has been reprogrammed and has the VIN & data from a 2007, orange 997.1 GT3 RS. (Why, I'm not yet sure, but if not for performance reasons, it may have been so that it communicates with the GT3 instrument cluster in my car.).
I have a Carista for my 2018 B9 A4 Avant. It is remarkable what hidden toys you can unlock with this bit of wizardry.
I wondered if the Porsche system could be coded to tell it that it has sport mode to see if it selects the 2nd map I suspect may also be in my modified DME.
My brain is hurting. But I love a challenge like this.
BTW. I have no desire for more power. The car is quite frankly, bonkers. But. I do like to play around. It's not a big deal if it's not worth exploring as I have other plans for these new switches any way, which is why I sourced the new switch bank.
Need an expert for this one me thinks.
Note. Even though the GT3 switch pack is slightly different inside and is marked TC off (my original switch says PSM off) the pin locations are consistent & resistor values were close enough to give me confidence to fit. The PSM still turns on & off correctly. Result!
The PASM switch have gained will be used in a future project. Just so happy to have lost the spoiler switch.
Original question.
Can you let me know what the SPORT button does on a 997.1? Is SPORT mode only available on S models?
I assume that the small extra light on the SPORT switch illuminates when in Sport mode.
Q1. Is there an indication in the instrument cluster that the car is in SPORT mode?
So, I imagine that the DME will select a more aggressive map with improved throttle response etc.
Q2.
Is this instantly noticeable when you select sport. Does the idle speed change for example?
Q3. Does the 997.1 have exhaust valves & if so, are these influenced by sport mode?
Thanks in advance.
