Hello Bill, Hello Carl, Hello Richard !!

I've got the original Mercedes Fan Controller and this Version 2 has been on my todo list for a couple of years...

I've got access to the same PWM controller that Tom uses as we use them in my labs at work. I've been long contemplating total automation via some sort of PID controller that'll ramp fan speed up and down as necessary. So far - with casual research - I haven't found one that'll operate at 20Hz.

I've chatted with Tom a few times but we've haven't really done anything yet.

I recently retired so this project may shortly get some attention again.

And from the previously provided Dynamic EFI diagrams (Thank You Bill) - I figure that the PWM feed is in the terminal E to fan+ connection. How does this map to the 5 connections on the Mercedes Fan ?? (I'd go and look at my V1 but the coach isn't with me - it's over in storage).

Looking forward to any collaboration !!

Thanks again,
Steve W
