Hi!
The car is a 2008 Subaru WRX STI. Using an M150 with a GPR based firmware and a pnp harness.
I need help with a single issue regarding A/C setup, I might be overlooking something, but its taking me quite some time to figure out.
The I/O is setup correctly. When I push the A/C button in the car, Air conditioning Request switches it state, and the Air Conditioning Clutch State as well, so the A/C system works.
The only problem is that the driving polarity of the Air Conditioning Request Resource is inverted.
When the A/C button is off (in the car) the M1 ECU recognizes it as On, (and vice-versa)
It might seem as easy as just inverting the clutch polarity. If I do this, the system works correctly, but the compensations that are applied when Air Conditioning State is On doesnt work, because they need the state of the A/C to be On in order to be applied.
Since I am using the Universal Digital Input 8 as the request, I believe this issue would be solved if the M1 could understand that 0 is On, and 1 is Off, and not the other way around. Is it possible to be changed?
The second issue is that, once I start the vehicle, all of the accessories (such as Radio, A/C, clock, etc) are off for around 40 seconds... After the engine is running for that period of time, the accessories relay turns on, and everything comes back to normal. I searched for the word " delay" everywhere in the map, but nothing seems to be related to this issue.
There is a function under the STI specific tables called "ACC Off" , but it is currently not in use.
I have no idea what to look for here, any help would be appreciated.
Thanks in Advance.
