So, purchased the 991 Aerokit Wing from Suncoast a while back for my 2012 911S. Removed the OEM wing, installed the aerokit wing during the winter. Didn't bother with the new control unit for the sunroof but did have to do some re-wiring on the rear-end electronics control unit b/c of my production year on my car. I followed the instructions provided step by step. Last step was to go to dealership to have it programmed so the car knows the OEM wing that moves up and down is no longer there and the Aerokit Cup wing is now in place. That was what I did today... Kind of a disappointing trip to the dealership...Went there to finally have them program the car so it knows the vehicle is now equipped with XAA - Aerokit Cup. I even saw it on the computer from the mechanic who was using PIWIS 3. When i left and proceeded with testing out to make sure I don't get the spoiler loss error message again, it happened again. :( When i went back to the dealership to show the picture of the "Spoiler Loss" error, he plugged in his computer to my OBDCII port and launched PIWIS 3 (not PIWIS 2 since they upgraded). It clearly showed the car now knows XAA - Aerokit Cup. Didn't know what else to do now. sigh...any suggestions would be greatly appreciated
As many of you know, I've started a company to sell electric spoiler ram (eRams) kits for the 996 and 997 turbos - replacing the finicky yet over-engineered hydraulic system. It does away with all hydraulics. Anyhow, I'm playing with the logic that was ultimately programmed into the ECU. I'm wondering if there is a way to get the logic from Porsche? Or perhaps someone here has some better insight? At this point it seems to me as something like this: To raise wing: 1. Momentary push of switch or cluster speedo (75 MPH) signal to ECU to raise spoiler. 2. ECU send current to relay 1 coil which activates motor in one direction. 3. Wing travels up and closed circuit from top limit switch (passenger side ram on top) within ~14 seconds. If no limit switch contact - then WARNING at cluster. ALSO...Wing will not go down either by switch or cluster speedo (37 MPG) signal from ECU to lower spoiler. Similarly to lower wing: 1. ONLY for cluster speedo (37 MPH) signal to ECU to lower spoiler. 2. ECU send signal to relay 2 coil which activates motor in other direction. 3. Wing travels down and closed circuit from bottom limit switch (passenger side ram on bottom) within ??? seconds. **this is different than "UP" as the push to lower switch can be let go at some point before the wing is fully down. Therefor the time-out counter only works with the speedo signal... If no bottom limit switch contact - then WARNING at cluster Not sure if the wing will go up "at next signal to raise" unless fault is cleared (cycle key off). Any info out there?? I'm also wondering if there was a logic change between '01 and '02 model years. There seems to be two wiring diagrams out there for them.
