I am using version 2.5, Cummins ISC. Instantaneous mpg appears correct but rolling mpg reads 0 and fuel remaining doesn't change ( so miles remaining gives a bogus reading too). The odometer gallons used shows 10767.6, and seems to increase correctly but with an incorrect base (!) Computer is an Acer Iconia 510 with win 8.1. All suggestions gratefully accepted! Frank Halasz
So, Rolling MPG and trip gallons (10767) wrong. Hello Frank, sounds like we need to do a little tweeking. On 'Rolling: 1. Rolling MPG Buffer Size. This should be 150. 100~200 is not unheard of but, the larger number will smooth out the numbers though give slightly delayed results. Why giving a '0' ? Not sure. or...try this if that all looked fine: 2. On the Tank Minder properties, find the check-box and change it. check or uncheck it. I've seen this work on an older setup (a information-stingy 1998.) The last time this came up I un-checked it. Your mileage may vary. On the Trip gallons, options are limited. 1. Reset the trip (just this trip) to reduce the value. or 2. Start from Day One (with info taken from the ECU) to increase the Miles, reflecting ...starting day one at the factory. I'm not sure there's a way to edit the trip file. This has come up on the forum over the years--its the source of much of my own information. Tedious...but a good to see others have struggled with this and sorted it out. Search terms: Rolling MPG fuel remaining cheers -- Art Renda Documentation Central Silverleaf Electronics (888) 741-0259
Something similar to that happened to me. I'm using the USB JIB and when I shut the engine off, say for refueling, several of my gauges stopped working. After restarting the engine I have to shutdown and restart VMSpc in order for those gauges to start working. I'm planning to add a 12 volt source with a switch to the JIB so it is powered all of the time while I'm traveling. Just a thought pfhays
Okay--that's totally weird. Hello Pete; could you take a quick census on which gauges stop? This is a new one and I can't even think of where to begin. Maybe there's a common thread among them? cheers Art //
It was unchecked, now it's checked. I think mpg is working but I haven't done a Fill Tank yet. Probably will fill soon while prices are low. Who would have thought to look under Engine Corrections for that checkbox?
Hello Frank If memory serves, it ended up under engine corrections as we don't have a specific section for fuel management--just fuel-tank monitoring. We're massaging engine (ECU) data as they may or may not need inclusion. Its this example however that leads me to want to figure a more logical and uniform...maybe even intuitive(?!) layout for corrections and tweaks. This is my *favorite* for adjusting for poor ECU fuel information: First, ignore the Engine Corrections, go to Communications. Why not?! Now choose some inanimate object that has nothing to do with fuel: like Advanced USB JIB Properties. USB...a cable; right? Nope: a math whiz! Now, a checked-box is claiming the JIB will do the math for fuel then metered. ...which it does pretty nicely... Yet still an odd road to travel. Maybe in v4.1 we'll have a Fuel and Engine corrections, patches and boxes ...or something all worked out in one area. Keep me posted ;-) Art //
But engine hours and total mileage are showing only the offset that I entered. (Tried to install Win 10 on my tablet and wiped some files in the process.) Where should VMSpc be looking for that info? Or should I give up and do a clean install?
