I use TPS setting of 6...
How did you arrive at that number?I use TPS setting of 6...
I left mine at 24 and have had pretty accurate results, lately anyways. I'm wondering which way the numbers work. If using a value of 0 disables it then does that mean to trigger it earlier you would raise the number? IOW, the larger the number, the sooner (and further from actual 0 TPS) the cutoff would trigger? If so, then the increment must be pretty small if both 6 and 24 are acceptable.Some vehicles will turn the fuel injectors off while
coasting – this is known as Fuel Cutoff. ScanGauge
attempts to detect the fuel cutoff condition by
comparing the open/closed loop indicator and the
throttle position. If ScanGauge improperly detects fuel cutoff, then you may see fuel economy being
reported as 9999 MPG or 0.00 LHK.
The CUTOFF parameter allows you to set the point at which ScanGauge can determine the throttle is
closed and in the fuel cutoff condition. The default value of 24 is usually correct for most vehicles but may
need to be adjusted. This setting is not critical but is best at about 4 above the no-throttle TPS value. You
can choose to disable the fuel cutoff sensing feature of the ScanGauge by setting the value of CUTOFF
to 0.
Hi there. Please elaborate on your statement.I use TPS setting of 6...
TPS should be 0 at idle. TPS is Throttle Position Sensor - it senses where the throttle (the go pedal) is positioned.
If you are not pressing on the pedal it should be at 0, if you have the pedal to the metal, it should be at 100 (as in 100%). If the pedal is halfway pushed down, the TPS should read 50 (as in 50%)
I would fix this problem first before worrying about the SGII. This could be your problem...
I never see this display... when starting (after overnight, etc.), starting the car produces --- in the avg. display. That's as weird as it gets. The rest of the time, it displays some number but never 9999LHK. Dunno... that's a question for the mfg. All the basic settings correct like Diesel-A vs Diesel-B, etc? I am talking about daily average, BTW. Rarely look at tank avg.I reset mine and it seems to work ok.. however when I stop at a light I am still getting the "9999LHK" message and my average increases.. Anyone else have this issue?
Once I start driving again the average goes back to where it should be..
Thanks
Uhhh, that makes no sense. My experience has been that idling is way more detrimental to my avg. mileage than I ever gave it credit for. I drive the same 35 mile route to work every day. A stop at the convenience store (5 min) and leaving the car idling will drop my avg. trip by 2-3 mpg vs not. Same if I warm the car up first. How can using fuel and going nowhere increase your mileage?thats correct, your average should go up when you are stopped at a light. Idling and going no where....
The reason this happens is because you have your Scanguage displaying in metric. The mileage is been displayed as liters/100 km - not miles per gallon.I reset mine and it seems to work ok.. however when I stop at a light I am still getting the "9999LHK" message and my average increases..

Actually, that made sense to me.. Because when you think about it.. the car isn't moving and it is using fuel, hence the LHK would increase.. because you're not moving.. but still using fuel..Uhhh, that makes no sense.

Just to argue my point, the person talking about 9999 is using the metric system and when you are stopped your fuel efficiency number goes up and your mileage goes down. (L/100km vs mpg).Uhhh, that makes no sense. My experience has been that idling is way more detrimental to my avg. mileage than I ever gave it credit for.

I called ScanGauge customer support and they said that some cars don't report TPS to the OBDI. It seems strange to me that this would be the case with my Jetta Sportwagen, since so many other users here are getting TPS readings. Are there any other 2013 Sportwagen drivers here who are getting TPS readings from the ScanGauge 2?Hi All,I just installed a ScanGauge 2 on my 2013 Jetta Sportwagen TDI, and I can't seem to get any reading from the TPS gauge. All the other gauges work fine, but this one is blank. I really want to see this data so I can program my fuel cutoff setting correctly. Am i missing something obvious? Has anyone else run into this issue? Thanks for any help!
