2. We know you doubt we need 2 modules for our dual fans but if we end up going that way, do you suppose the ECM will care that there are two modules receiving it's PWM signal vs one?
We are doubtful that it would be an issue since the ECM is just switching to ground but thought we should ask.

Thanks again for your help!

1 -Does not need BCM input in addition to AC pressure. Between all inputs for fan DC request, largest wins so just need to have AC pressure switch and cals populated for fan % vs. AC pressure.

2 -I've never tried running 2 PWM modules from the single output driver, so can't really say if it'll work or not.

All LS1 controllers I've worked with (P01, P59) are set for descrete fan drivers, not PWM. Can always set up to run parallel/series for 2 speed operation.

It's been so long since I've worked with one of those (outside a car it came in) I'd have to look to see if can run AC pressure switch in to control fan output.
