Hi,

Are the below parameters available for Datalog in VCDS?
I can't seem to find these parameters anywhere in my buddy's VCDS on my 2014 A7 - want to get VCDS for datalog, but defeats the purpose if i cannot find the following.

What i'm looking for, but unable to find:
1) Charge air pressure actual value (hPa, actual boost + ambient)
- In the B8 S4 forum, VCDS calls it Intake manifold pressure; absolute, which I'm unable to find for C7.
- there is a Turbocharger intake pressure sensor, but not sure if that's more for the 4.0TT

2) Charged Air - Intake air temp (IAT)
- Unsure if Intake air temperature parameter measures temp before throttle body, or charged air temp after heat exchanger.
- Or is it Charge air temperature sensor?

3) Supercharger bypass valve
- In b8 S4 forum, it's called RFP_AV (bypass valve %), again, not found for C7.

thanks!

When you had your buddy's VCDS plugged in, did you save an autoscan by any chance?
If yes, please post it and someone will be able to look at the controller on your car and tell you if those parameters are shown

Best regards

Hi there, I asked him and it looks like he did the scan with a obd eleven?

The parameters available to log are not determined by VCDS; they are determined by the software in the ECU in the car. It's nearly impossible to give you definitive answers without knowing exactly what ECU the car has and what ASAM data it uses.
