So I bought my OHC almost a year ago and originally put in the US/MET and ON/OFF DIC in it which I never got working but at some point last year I picked up a MODE and US/MET one and yesterday I finally got it installed. Works great! Spent $60 on different colors of 16ga wire though. Made my own wiring harness and kept it clean, used the quick connect adapters for all the splits I needed for the Illumination, VSS, RAP, and the LED Dimming Signal from behind the radio. Used the ground and constant 12v from the two map lights, ran a wire to my grille where the temp sensor was, and it all worked!
Range seems proper to me, I usually fill up about every 250 miles anyway and with the guestimation from the Range it gives me about 270 from a full tank -- so good enough for me! Compass; Temp; Instant Econ; Econ all seem to be correct. Fuel used is 197 gallons which I call BS; truck has 194,200mi on it and no way since it gets 13mpg usually!
