The reason I think this is because it will usually drop a good 3 to 4 tenths sitting at a light for a minute or so. With 100,000 samples you shouldn't see that kind of drop for that duration.

My questions are:

How many samples does the gryphon actually use and how far apart are they?

How can I increase the ammount of samples it uses?

Thanks

The gryphon will keep recording until the alotted memory is filled up. Unfortunately the only way for it to increase the number of samples is to run longer. Otherwise it would be just as accurate as the instant mpg. It will keep taking one reading every second. (But I'm not sure since the data log will take 5 per second)
Instead of looking at it as 4 tanks which can run out quicker depending on where/how you drive consider the memory full after 28 hours of driving. If you have a 30 minute commute to work, after a month you'll have your average.

If you accidentally cleared the average mpg then you lose all those samples the programmer uses for refrence. There are a few ways for that to happen. One is to hit the enter button twice, but the most common is to have the programmer get unplugged or have the power taken away some how.
