So this project seems to be coming along quite nicely. I see a very reasonable schematic and good code. How close do you think you are to actually testing this in car and having a functioning MPG meter? I'm trying to decide on waiting for this and building one myself, or hopping in on that $135 ScanGuageII group buy going on in the forum. I have until Tuesday to decide. (Though I may pick up the SG and sell it later if this turns out to be sufficient for my needs).
One final question - in regards to the calibration techniques mentioned - they all seem to start out with a "guess". Are they suggesting that the guess is for initial calibration and then finer calibration is required later? I may not have read closely enough (and I haven't yet read the code), but I didn't see where the fine calibration comes in.
Thanks again for all the work being put into this. It's certainly looking good!
