Logging IAT values

[suprashy]

Hi folks,

is it worth tapping into the THA signal at the ECU to log IAT? Looking at:

http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=FI&Page=60

Does 1-3V mean IAT = 68 deg?

What if we see other than 1-3V, what temp. would that be? Is there a way of knowing or is this approach a no go? I'm using the Innovate LM-1 and RPM Converter.


Thanks!
