MPGuino settings for 49 state Honda Civic VX.

[WD40]

stewie:
the latest # I have tried is 258562433 it seems to be the closest I have seen, I have only run it for 100 miles tho so a full tank may be off a bit.
In the mean time I have altered all my gaslogs to adjust for the tires size.

WD40 sweet bro. You're great man! How does your ODO mileage compare to Guino mileage after tire adjustment? the gal/sec number you want is probably that matches or is closest to those ODO match after tire mileage adj with Guino mileage. I'll put in some input as well after i get it installed properly this weekend. We'll figure this out. I really do appreciate your and Andrzej input. I have a starting point with your figures to tweak it now where wiki number was so off i would spent a month or more on getting it right so for that WD40 i thank you much. BTW what is our tires PSI if i may ask. I just bumped mine to 45psi. Max i can do is 50. In winter i ran 34psi. My goal is to run 50mpgs or plus constant which i can only do occasionally now.

There are many things you can add to MPGuino, right now I'm working on temp gauge, range gauge (how many km/miles you can ride with current FE and given tank size), and coast down time and distance meter.

If temp gauge will work as it should I think I'll include temperature management system into it. My guino will close & open grill accordingly to engine temp. Or I'm hoping it will

Anyway when I get my code working I'll post it here and maybe I'll add it to MPGuino wiki. Problem is that I'm working with "canadian" version, but code is very similar so it shouldn't be hard to include those changes into v0.86 "official" code. Maybe I'll make two versions of my code changes for canadian and official version. If there will be someone interested

stewie:
I ran my tires as high as 65 psi but there is no noticeable difference in MPG between that and the 50 that I run now.
The big difference is less road noise and bone jarring.

I forgot to answer your question. Yes you can upload changed code using ISP, and simple serial or parallel to ISP cable. Or using any Atmel compatible ISP programmer.
My MPGUino I've build on my own using Arduino. Good thing is that I can make any changes I need and it's much easier with all the ports available.

Small note on your rpm code:

The "RPM" and "rpm":"rpm" is redundant. An improvement would be:


void doDisplayBigRPM() {bigNum(instantrpm(), "RPM", "");}

or

void doDisplayBigRPM() {bigNum(instantrpm(), "", "RPM");}

Andrzej thank you. Still will need to research into how to do that. Found some cool info.

Guys i did test drive today (with 500 miles numbers from WD40) and downloaded app with decimal speedometer with multiple sats. So Guino reports speed under (within .30-.50mph) and miles (within .40-.60m) under GPS so i guess i'll have to tweak those numbers as they appear off which would explain the mpgs being off.

stewie: please let me know what #'s you come up with that I can test on mine.
I've just gotten used to close enough for settings, but closer to perfect is always welcome.

WD40 i am extremely thankful for you providing me those numbers. They are close. Main thing is to get miles right to GPS miles. I'm trying to figure this out.

Andrzej how do we tweak speed. I think that should be accurate as guino taps into Vehicle speed sensor. Does VSS gets adjusted from those two variables we provide or mph is provided from VSS as static value?
