1G-GTE Rev 3 ECU Adjustment Pot

[Karma Supra]

Does anyone know what it does??? - Its under a small cover held on by a screw on the side of the ECU. My stock one has it, as does my mines ECU, it seems rev 1 and 2 engines don't.

I have asked before on various threads but no one knew, I thought I'd ask again incase anyone ahs discovered it, or missed my original slightly off topic question in another thread

im gueesing open the casing .. read resistance for where it joins the circuit board.

note this number then play with it ... with the original reading you can turn it back to OEM
if it fouls things up.
