I wish a PHEV conversion was as simple in the 2003 Prius. I'm looking forward to yours.

I think the coolant hack must have some emissions downsides as you are telling the ECU that the coolant is warmer than it is. I'd rather just preheat as much as possible. I will probably have two coolant heaters set up eventually.

Bob has done this hack and probably knows the emissions angle.
