So I bought myself an OBD plug (one of the wifi OBDLink ones, works a charm) and a copy of Torque Pro on my phone....I'm trying to find out as much as I can about using it to display certain bits of info on my phone, but I'm a: pretty lost, and b: overloaded with questions...hopefully others on here have played around with this, I noticed there hadn't been many recent posts but here goes anyway:
1: I have the "Current Drive Cycle Status" info block displayed:
Secondary Air Sys
O2 Sensor Heater
I usually notice that O2 sensor can take a while to say complete (out of 'not avail', incomplete and complete) when turning warming the car up as I'm guessing the sensor has to heat up (are standard o2 sensors narrow or wide band?) Driving home today I was looking at that page and it took a solid 10 minutes of driving home to change over to complete as i was pulling up outside. I turned it off for maybe 5 minutes, then went for another drive and it was back to saying incomplete (as well as the catalyst) and didnt change over to complete in the 5 minutes i drove around the block. Surely the system would have been hot enough to use the sensor straight away...so how come it stayed incomplete? I'm getting bad fuel economy at the moment, 390km to a tank of 98 from full to the warning light... just a thought.
2: I had both ambient and intake air temp come up in my list of available PIDs, so i put both on but noticed they change identically, so i can only assume (by comparing the number to the ambient air temp displayed on the cluster) that it is actually intake air temp? Does anyone know where there sensor is? I'm guessing post-I/C?
3: I also had transmission temp show up as an available PID at one point, but i noticed the oil temp was matching to the engine coolant temp suspisciously well...is it trying to access the wrong part of the ECU for that information, getting confused, and showing coolant temp as trans oil temp? Can someone possibly explain how we get something like that up? I know it comes down to custom PIDs, but has anyone ever published a list of things that can be displayed in an RA/Evo?
4: Can anyone tell me if the following info can be displayed:
- Transmission temperature
Oil pressure (I'm guessing this is unlikely)
radiator fan relay (as in are they running or not)
A/C system relay (same deal as above)
Current SST gear (Would I be right in thinking that can be done in Torque Pro by using a formula to analyse RPM against road speed to work out likely gear?)
5: Can anybody recommend a good place for info on setting up more things to display with Torque?
... for now
