is there an email or someplace to ask to see if a perimeter option is in a ecm but just not defined in the editor?
I see a lot of ecm's have the drop down box option to select relay control or pwm for cooling fans. mine doesn't show pwm but all the tables are in % just like my e38 ecm that does have the option and was easy to swap in a brushless fan by changing the box settings.
it's a older low volume ecm, so I understand it isn't really a cost effective thing to waste time on. but I'd love to switch it to newer brushless fans too.
it's a 67A ecm in a 11 hybrid yukon.
