Excuse me too for confusing the two Cyl Head Temp and Catalytic Converter acronyms CHT and CAT. I know that CAT is inferred/calculated, and probably is not an EV factor. Also forgive me for getting off subject, but sometimes it all blends together, because the grill cover is utilized to raise and maintain fWT to promote quicker EV and sustain it longer. All beautiful music playing together to form a song

I'll be monitoring SGII-xgauge fWT, CHT, SoC, and Outside Air Temp (OAT) to determine any absolutes in regards to the 08 FEH AWD going into EV, and report on the appropriate thread. But I'll have to wait until my wife lets me drive the car. I regularly drive my 02 Ford Ranger now that it's too cold to drive my 72 VW super beetle Luckily, I have learned MUCH with SGII connected to Ranger daily, and could talk endlessly on those findings, but they don't relate directly to FEH. Learned 90% from postings on this site. GREAT!
