I'm trying to re-enable discrete control of 2 fans in the eRod LS3 ecm. I've done the hardware side of splitting out the fan control wires (which ship hooked up to the same relay). I know there are a couple of other people doing the same so I imagine any responses will help them as well.
I do not currently understand the "Fan State Transition % vs Current State".
Working backwards, I start with my ECT. I look that up in "Desired % vs ECT", which is 0/100 depending if you're under/over 206F.
I have seven "States", and my confusion starts because I don't know what a state is, why there are seven of them, when a transition occurs.
After that I think I understand the "Output Control vs State".
So, could someone give us a little brain dump on how the states work? I did search for "fan state" but didn't find much - but if it's been done before, by all means just point me at the thread.
Thanks!
Dave
PS: Perhaps the default non-useful values in my ECM table are confusing me - if there weren't all 100, I could see sort of how it'd work. So I'm guessing these values need to change to "define" the states? Well, I guess you can see I'm over my head and need to source a little assistance :-)
