PLX EGT via EIO Input

[jakebdb56]

Just curious if anyone else has logged EGT through the EIO. I can fudge the calculation and have it appear 1/10 or 1/100 of the actual figure, but was curious if there's a workaround for this?

The linear for Fahrenheit comes out to V / .00185 + 32

HPTuners only allows three decimal places for the voltage calculation, so I'm kinda screwed there

Attached is the linear output image from their manual.

Suggestion: plug .0028 and 273 into the user-defined inputs to start and see you a very close workable scale in Kelvin and then tweak from there. You can always convert back to Celsius or Farenheit once you can log it.

I'll give that a try and probably just make a custom histo/PID to convert to fahrenheit. It's one of those things that I'll unrealistically be looking at the EGT gauge while making a hit, but want the data for nitrous/FI. Thanks for the input

Sorry for missing the point.....if I would have tried it I would have realized that Celsius works great too if not better...... .0033 and zero......cheers

Use the list view instead of the transfer function. I do this for my wideband calibration in lambda as well because the equation doesn't allow enough resolution in decimal places.

To make it simpler you can erase the entire list and re-write it like this:

0.00,xx.xxx
5.00,xx.xxx

Once you input the parameters it will automatically populate the graph to the right of the list and you are setup at that point.
