First post here...New SGII on 2006 Honda Pilot.

I know MPG needs calibrating - finishing up my first tank. However, I noticed a 9999 display when I know I maintain (not accelerate) the throttle (below TPS 24). If I'm on a flat or slight incline and maintain throttle position I can hear the engine on and feel it but SG still reads 99999 and 0.0 GPH - can go on for quite a while. This results in much higher MPG calculations (I doubt I'm getting 30+MPG on this guzzler).

My question is should I consider lowering the TPS cut off or just calibrate at fill ups until I get an accurate approximation? I suspect there's no simple answer here but I would like to know others opinions either way.

Also, is there an "absolute" TPS cut off value or is it relative to SG implementation. In other words, if it's absolute then in theory Honda should be able to tell us the real cut off value. If it's a funny number that SG calculates then I guess there is no absolute just a continuous guessing game.

Thanks for a great forum!
