The motions are not the best because the program where this simulation was done requires some features that the computer I'm using does not have it, but you can get an idea of the project.

This project is very good.
Does MPGuino already work with this Nextion project?

I'm sorry, but it still does not work in MPGuino, nor do I know if it will work in the future, my programming knowledge is very limited.
Only the t vago one can help with this.
If you have programming skills to do so, go ahead with the project.

Thanks
José Rodrigues

Too bad it seemed like a pretty good project.
I'm also not a programmer, so I can not help.

Evening T Vagos,

I've recently found this project and am trying to get it to work on an Arduino Mega 2560, it compiles fine and uploads to the board, but my LCD is blank, I've tried using an LCD (wired as legacy LCD) and tried doing it via the Adafruit one, it's just a generic LCD, VCC,GND,SDA and SCL.

I get nothing from the serial monitor, have tried several versions of arduino IDE, I'm a bit stuck really, hoping you can help me out, I'd love to get this working but seem to be running into nothing but headaches,

Thanks

Hello everyone,

Is it possible to change fuel economy from l/100km to km/l? In Brazil we use usually km/l.
I tried to find the function in the code but it has more than 10000 lines

Thanks,
Bruno.

Hello,
with the latest version cant find a way to exit configuration menu with legacy 3-button setup. help please.

Hi T Vago and others who may know,

Is the variable voltage output for remaining fuel working?

I downloaded the 8-02-2017 code on the first page, un-commented out the relevant define lines, set the OutPtPin 1/2 to mode 5 or 6, however i get no voltage output on pin 11

I have a based RC filter on Pin 11 (5kOhm/ 2uF)

Any input would be appreciated

Has this project ended? I would like to try this myself on my 94 Metro XFi.

No, the project has not ended, it just got paused for a number of years.

Oddly enough, I am looking now to install an MPGuino into a 2002 Suzuki Swift. This would be the Hungarian Euro version of the 1997-2001 (?) Geo Metro/Pontiac Firefly, and has the same apparent limitations - chiefly, the VSS off the speedometer needs to be debounced.

Updates -

Examined my code from the last time it was uploaded onto GitHub, made a zipfile from the code, and updated the first post in this thread with the zipfile.

Added the ability to display gallons/100 miles and km/L values for fuel economy. Graphic units added accordingly. Swapping between MPG<->gal/100miles and L/100km<->km/L is a bit-wide parameter setting, much like swapping between US SAE and metric displays.

More progress made on ability to output analog voltages corresponding to tank quantity used/remaining. Hope to have it in testing by next week.

Cleaned up #defines related to underlying processors. Separated ATmega32U4, ATmega2560, and ATmega128 from definitions for Tinkerkit LCD, JellyBeanDriver board, ArduinoMega2560, and legacy MPGuino boards.

Configuration changes made to Tinkerkit LCD - it now can support TWI just like the other boards, but it lost the ability to output on the Serial1 UART. Oh well... I will likely enable USB serial0 output on this board instead.

Identified ways to further separate the low-level MPGuino code from the LCD display/button interface, so as to facilitate using MPGuino with things like TFT displays and Bluetooth.

Moved some Chrysler-specific code around a little. Maybe there's some other automaker who also uses a returnless fuel system and does not adjust fuel pressure to the rail...

Reviewed matrix math code in preparation for implementing both the microseconds per gallon parameter calculator and the coastdown calculator.
