Not really, because there's no way to come up with a 100 percent accurate speedometer. It will always read higher the more the tires wear. Also, I'm not aware of any sensor that accurately measures the actual fuel flow. As far as I know, that's calculated based on injector pulses.No problem k3.
Question: do you think there is truly a way they could ever come up with a 100% accurate mpg display?
From what I read it sounds just about impossible, but I'm a lay person & don't begin to understand all the tech aspects.
Why? That's easy..... because as the road surface changes, up and down, and as your foot pressure on the gas pedal changes, more or less pressure, your gas mileage will also change, second by second. If that info is not helping you become a better driver, then you're not using it correctly.I did not trust my 2012's gauge so I checked it for about 4 months each fill-up. Turned out it was very close to what the guage said. At least good enough for me. I have an old Scanguage in my 2001 Astro and one of its features is an instant fuel economy reading. The funny thing is that the reading on the overhead consul is slow to change and often stays the same for weeks. The instant one on the Scanguage changes all the time. No idea why.
I meant to say but did not do a good job, is to note the difference between what the overhead console said and what the Scan gauge said. Both, I assume using the same data. And yes, I really like the Scan gauge.Why?

I've had my own Scan Gauge II now installed on two different cars, over a six year period, and I do believe that it has made me a better driver, at least a more conservative one.
Besides the MPG and MPH readings, you can set the Scan Gauge to display two more readings. I like to watch my engine temperature and Alternator output.
The Scan Gauge can also display any CEL (Check Engine Light) code and even reset it if you like. I feel like it's probably the best $159 I ever spent on my car(s).
