Epic. I need to check the tinyiox. Are you going to run the fuel pump fast too?

TinyIOx should be the same, I believe the CPU's use the same if not similar timers.

Yeah, I plan to play around the high frequencies with both fuel pump and cooling fan to see if there's a sweet spot. Now I'm regretting not going electric water pump, PWM all the things! The CAN-EGT+ allows for 4 PWM circuits, and I think they all run on the same timer.

Check out the spreadsheet linked in this post. The frequency possibilities are endless.

Awesome. That's what I remembered.

My only worry would be having fuel pump on an external board. Would worry about that a bit

Yeah I've thought about that too. It's probably fine? If the CAN communications are robust, and the protection circuit to the expansion board is adequate, so I don't foresee any issue.

I'm sure its probably fine. I will still worry about it. Thats how i roll
