I have had it in for about 3 days now, but get in too late after work to report fully, so I waited until today. I still have to get it all figured out yet, as there are user programmable functions to show HP, etc., that I haven't had time for yet either. Also, I haven't had time to be sure I have the parameters set correctly for the GX. It seems to think I have a gas tank size of a regular Civic, skewing many figures so far. I'll get all that figured out eventually
What has been very interesting are the TPS (throttle position sensor), and the Instant Miles Per Gallon display (it displays 4 things on a screen, user programmable). The manual says you need to make sure that when off the throttle, the TPS reading is at least 4, mine is at 14 stock. That means when I let off the throttle, it reads 14, and full throttle, it reads 78. Most light-footed cruising in nice conditions can be done in the low 20's and even high teens. It tends to vary from the slightest conditions like wind, slight slope, etc. But what I did notice that using it, I can often drop it by 1, with and increase of 2-3 MPG on the readout, without substantially affecting my speed. If I start at 65 on a given flat stretch, I can run at a throttle position number that may gain a MPH over a mile, or run 1 or 2 lower and lose 1 MPH over a mile or so, but get 3 or 4 MPG better at the lessor setting.
Also, the fuel cut-off definitely works. Fuel will only cut-off at no-throttle (14 on my TPS reading, which = 0), and it doesn't do it below about 25 mph, as the engine may stall as the car slows. When it goes into fuel shut-off, the Instant MPG reading goes to 9999, while the TPS is at 14. Going east on Hwy 15 over the Pachecho Pass, I can let off the throttle as I crest the summit, and go 3 miles using no fuel. I only do this in light traffic, as I peak at 76 MPH, and bottom out at about 52-53, before I finally have to get back on the gas. The Cat Convertor is hot enough from the preceeding climb to go the 3 miles without cooling so much that the computer triggers fuel restart.
More later, feel free to ask questions
