Dial On Side Of 32 Gts-t Ecu?

[Johnny Cash]

hey fellas

Just wondering what the dial is for the on the side of the stock 32 ecu? I just discovered it today.

Thinking to turn it up, but not sure what it'll do, and I figure at least ONE of you would know.

Thanks,

Adrian.

You can touch it. It is used to put the ECU into diagnostic mode.

Turn ignition to ON, then rotate the dial fully clockwise, hold 2 seconds, then rotate back to where it was. The LED next to the screw will start flashing a code (or series of codes) - <search> for how to interpret the flashes, and what the codes mean.

The other use is (apparently) a fine control for idle speed; however I've never really noticed any difference when i've twiddled it.
