Thread: Variations Between Scangauge II,Torque, and DIC

Greetings,

My scangauge came today and Ive been playing with it since I got home from work. Ive noticed some variations in the data between SG, Torque and the DIC. For the record, I am using torque with a cheap, Amazon sourced ELM327. Here are a couple examples:

Voltage:
DIC 14.4
SG 14.1

Water Temp (at fan kick on point):
SG 218
Torque 221

Throttle Position(idling, revving the engine slightly):
SG 12%
Torque 15%

Gallons/hr(at ~750RPM idle):
SG 0.38
Torque 0.59

Im just curious why these values differ, especially since both devices pull their data through the OBD port. Which is more correct, Scangauge or Torque? I would lean towards the SG, given its price and reputation, but thats just me. Has anyone here tested these devices and if so what were your results?

Thanks

Did you get the scan gauge 2? Does it till you KR

Im not sure why they differ, they do the exact same thing. plug into the obd2 and send what the pcm is saying to the screen.

Are the pids on your Torque app right and does the Torque app have all the current updates?
