AC shows on in TS even when conditions turn it off

Post by jsdevel »

In TS, whenever I have my AC switch turned on, the green light is on after the specified idle up delay, then it never turns off, even when I set min rpm artificially high and wait below that for a while. Is there a way to make the Green AC indicator in TS only come on when the AC output is actually on?

So I looked at the source for the MS2/extra-3.4.2-release firmware, and I don't think this is an issue with TS. The AC status ligh does turn on and off when I flip the switch on and off. I think outpc.status3 &= ~STATUS3_ACOUT; needs to be added to the if (outpc.rpm < flash12.ac_idleup_min_rpm) { block inside the idle_ac_idleup function. I'm going to try this tomorrow to see if it works. Assuming I can get it to work by updating the firmware, should I take this over to the MS2/Extra development board?

Also, is it acceptable for me to copy bits from the source code here in the forums?

That did the trick! AC light shuts off now when min rpm threshold is reached. I'll report this in MS2/Extra Development. Sorry for the false alarm here. Issue filed in the MS2 Development board here.
