UltraGauge and DFCO - What value? - Toyota Yaris Forums

To those of you with an UltraGauge - what value did you enter for the Injector Cutoff (DFCO)? Did anyone do the other calibrations like travelling between mile markers to set the distance travelled?

I've been using an ultra-gauge for about 6 months now.

The only calibration I performed is to make sure I the "fuel used" is accurate -- when I first started using the UG I was pleasantly surprised to see I was easily getting ~46 mpg but it wasn't accurate! My multiplier is somewhere between 1.07 and 1.09, I don't remember specifically. I keep tabs on it and adjust every couple fill-ups to make sure it is accurate, and I now get 48+ mpg legit.

I haven't done the distance calibration for lack of a accurate, safe place to do it...

I really really like my UG and don't understand why all the talk is still about scan guage -- UG is just as useful, for a greatly reduced cost.

If you have any other tips for setting it up, let me know... so far I've been using the "don't have time" excuse.
