I've got a mostly stock 6.0L L98 swapped into a 62 vintage step van. Runs great using the E78 ecm.
I'm switching the clutch fan out for two 11" Spal electric fans. Im going to use an pwm controller to control them (autocoolguy high freq pwm controller) since the e78 is trash for controlling elec fans.
Here's my question....is there a way to trigger the idle to increase when the fans are running OR if voltage is below a certain threshold so that the alt will produce a bit more current? Similar to how ac will trigger a idle up....but based on something like voltage falling below 13v at idle or fans being on.
Or any other ideas....end goal being to help boost the alt some at idle when the fans are on so the voltage doesn't fall much.....I know I can buy a high output alt but I'm trying to avoid that.
Thank you for any ideas!
