I'm looking at adding some custom PIDs to RCP which I've tested in Torque pro (info was in a torque specific thread) which shows the correct values.
However using the same in RCP, shows maybe half the value that torque does?
Torque setup, which returned around 32c which seems correct based on a sunny 20c day.
IAT1 (post-intercooler):
PID: 0168
LONG NAME: Intake Air Temp
SHORT NAME: IAT
MIN VAL: -40
MAX VAL: 300
SCALE: x1
UNIT: °C
EQUATION: B-40
RCP:
channel: Intake Temp
postfix: none/none
PID: 0x0168
source data: 0x0000
equation: B-40
RCP first test showed null output. using 'Test connection' showed a value of 17. unfortunately i ran out of time to test any further at work. Do i need to do something with the source data field maybe?
Comments
I'm interested to hear what the real source data is when the test connection is enabled.
Max value should be 215 with that equation, so 300 seems a bit strange.
gotta love forum info! i guess 300 was just high enough so the real data was within that limit.
i'll try again on the drive home and let you know...
0x0167, B-40 is for coolant.
0x0168, B-40 for post IC, and C-40 for pre-IC IAT's.
What is the ’source data’ for IAT PID when using the test connection?
seems weird to me that the 'vehicle profile' screen shows 009 when using Test Connection, but live data shows 0x0000.
Are you able to connect the OBD-II reader using the Bluetooth Terminal app (assuming you're using Android, and have Bluetooth OBD-II reader (not Bluetooth LE or Wi-Fi)? I'm curious what happens if you do:

Type commands without the >, it is the ELM 327 prompt.

torque: postIC (B-40): 49, preIC (c-40): 36
super useful tool that, might come in useful trying to stumble upon other useful PIDs on the car
Thank you for this. Looks like RaceChrono is having trouble with that response for 0168. I will investigate.
thanks!
