Hi guys,

I'm looking to get my dic reading closer to reality on my LLY. It is about 10% out on both the fuel used and the mpg. It was also like this prior to EFI. I have my odometer calibrated to within 200' in 30 miles. I was thinking I could just adjust table B0781 to get my accuracy but that doesn't seem to be totally the way to go.
Is table F0101 used for any of the DIC info, like fuel used and mpg? or is it only used for sending voltage to the cluster gauge?
If I adjust table B0781 by 10%, will that also correct the fuel used on the dic?

Searches haven't turned up much info on this subject.
