Mpguino inaccuracy
I searched the forum before starting this thread, but was unable to find any related threads to my problem. I installed my Mpguino several weeks ago. I calibrated it over the first two tanks, and at the end of my last tank it was within 1/10 miles to my cars odometer, and 1/100 gallons used compared to the gallons to fill it. This was over the course of 450 miles, and 10.6 gallons of gas. I did this filling up at the same station, and using the same pump to try and keep things as consistent as possibly. With the numbers being so close, I did not calibrate anymore when I refilled the tank last.
I am now 215 miles into my most recent tank, and the Mpguino in reading that I have traveled about eight miles father than my cars odometer reads. I am confused how this could be, after traveling over 450 miles the tank before, and only being of by 1/10 miles. I have noticed recently that when using the instant mpg screen, that the reading at times jumps way up and down, but most of the time it looks to be reading an accurate number. I mostly use the current mpg screen, which would not produce the erratic reading like the instant screen. If anyone could help me figure this out it would be greatly appreciated. Thanks
