Open Loop
Edit 9/18/07, additions/corrections
Yes, it's normal. In fact it's our DFCO indication for the Yaris. Here's why: DFCO is by definition, an Open Loop condition, because it's a fuel cutoff. Closed loop is when the computer is using signals from various sensors to meter how much fuel to inject. At the same time, the amount of fuel injected is one of the things that creates the conditions that determine what the signals will be from those sensors. In other words, it's a closed control loop. DFCO overrides this and cuts off the fuel injectors. If you see Open Loop any other time, except briefly after a cold start, or briefly if you're drag racing or under very heavy load like climbing a steep hill, then something is probably wrong and most likely the check engine light will come on....and a trouble code will be waiting for the scanner function of the scangauge to read. If you were driving a manual transmission, you'd find it will also switch back to Closed Loop when the engine speed drops below about 1000RPM with it in gear and your foot is off the gas pedal. At the same time you'd feel a very slight surge of power. That's DFCO switching out to keep the motor from stalling. Then you'd quickly have to stomp on the clutch and throw it into neutral, or into low gear and go....or it'll stall anyway. On the other hand, scangauge fuel consumption calculation is unaware of DFCO, so it registers higher consumption than if you were in neutral. In my case, this helps offs offset consumption error calculation in the other direction. I have a 96 Chevy conversion van which sat with a dead transmission and engine problems for 2 years. I've been reviving it this summer....the SG came in really handy diagnosing....and I was surprised to find it too, has DFCO. Last edited by enkid; 09-18-2007 at 10:21 PM. |

ScanGauge gives by the abbreviaton "MAP" no value ( Yaris 1.8 TS)
Can someone tell me whether that is normal? Has the Yaris no sensor for the "MAP" value? Thanks |

Is it possible to change the $ sign into the € sign on a ScanGauge?

I was researching scanguage on the internet and read that an owner was having problems with a Rostra cruise control and Scanguage. Apparently they both were getting their signal from the ECU and if the cruise was on scanguage wouldn't work. Cruise would work if Scanguage was turned off though. Has anyone else had this kind of experience? If this is a problem, is there a workaround?
Mileage...I am not getting anthing near 35 of above in mileage, with 32.655 bing my best early last fall. I'm driving conservatively....although most of my driving is in town. I am just over the 2000 mile mark, and am hoping that it will improve as mileage goes up. Of course I realize that the extra cold winter that we have had here in Southern Michigan has taken its toll! I will be getting an oil change in the near future, maybe that will make a positive difference. |

I have an 08 with the dealer installed rostra cruise and my Scangauge works just fine.As for the crappy gas mileage it will get better as the temps heat up,snow tires come off and the gas gets reformulated to summer specs,on a trip last summer i was getting high 40'smpg highway,around town low 40's .

I ordered my Scangauge II today but I'm curious as to how it lights up? Does it automatically light when you turn the headlights on?
