Held RESET, put the key in, turned to ON, release RESET. Does the Gauge Test, then pushing RESET cycles thru plenty of menus. Most of which aren't decipherable, but there's RPMs, true MPH, coolant temp (in Celsius), voltage, and several others. After you are in the menus, you can start the vehicle and it'll stay in there.
This menu allowed me to do a quick grillblock test. I started the car at 3:07PM, it was 20*C. By 3:09PM it was at 45*C. Went out on the highway, set at 65MPH (GPS confirmed) at 3:12PM. My coolant temp went from 88*C up to 94*C and back, just bouncing between there at 65MPH, ~2300RPM.
Put the cardboard grillblock on at 3:28PM, the temp was 86*C. Driving back towards town about 4 miles, it stayed a steady 90*C to 92*C. I didn't trust shuffling through town, so I disassembled it. Btw, it was approximately 78*F at the time.
So, does that sound correct, a grillblock keeping the temps 194*F-197*F, while unblocked it kept itself 190*F-201*F?
