Android App "torque" Tips And Tricks ?

[Bulletime]

Wouldn't those temps make sense if you take into consideration that you're reading the temp on the outside, ie through metal that might be absorbing/insulating/cooling off? I dunno I could be on smack but if the temp externally has cooled off then it kinda make sense, to me anyways...

I agree with you. You have the collant running through the engine cooling it down. I wouldn't consider reading the EOT on the outside of the engine accurate.

I agree with both of you. this was all in an attempt to measure how accurate the equation that barnz posted up earlier in this thread. we're just not sure if its reading the correct temps

what we really need is someone with Forscan to take and compare temp readings with IR. or the sct x3 flash tuner(does this read engine oil temp)

unfortunately I dont have a lap top, otherwise I'd try Forscan myself to compare.

I have forscan. how accurate do yo think it is?

I assume it'd be more accurate than the torque app EOT, as that PID formula was guesstimated by barnz.

he used the PID number from Forscan but had to come up with his own formula for the torque app

he thinks its about -10c out

Well I am assuming this is the formula:

(((A*256)+B)*5)/72

​I may just go out for a drive...............

Interesting, readings on the pan should be reasonably accurate due to the way heat transfer works. The equation is wrong as I said from the outset.

I did expect eot to be closer to ect though. On a cold startup though the eot temp sensor should be quite close to ambient so that alone tells me its way off.

Can you do the same check against forscan's readings?

[masda74]

Went for a drive. keep in mind that it can take up to 30 seconds to a minute to swap between torque and forscan. I am not sure how accurate this is.

Results:

Torque -------------- Forscan

70 degrees -------------- 93.0 degrees

78 degrees -------------- 95.6 degrees

77 degrees -------------- 94.0 degrees

75 degrees -------------- 93.1 degrees

74 degrees -------------- 91.9 degrees

Please remember that you can not have both Torque and forscan running at the same time.

how long was your drive masda74?

[masda74]

15-20 mins mate. the first reading was after 5 mins of driving. I then drove for a while and when I got home I took a reading while the car was on.

I then turned the car off and waited a good 10-15 mins while the temp cooled down to take the other readings.

Why you ask?

what are you trying to say? I didn't drive long enough?
