MPGuino colour touch
 
**UPDATE: Unit now has configuable MPG or L/100 in settings**

http://glengineer.epizy.com/mpguino.htm

Over the last 5 years I've been running a version of the original MPGuino v0.8 adapted for a colour TFT display. I then adapted the unit to use a touch screen, replacing the long outdated 3 button setup from mpguino version 0.8.

It's been running in 4 separate vehicles seamlessly for over a year now and I think its time to farm out interest in the wild.

Only having a base understanding of coding it took a lot of troubleshooting to get her to work. But with GUI experience as a kid I have since refined and have a very streamlined product that has been stable with a range of different users.

Astute coders will notice the example script used for the circular rainbow effect, which works well for instant mpg display :P

Usability has been refined over the 5 years and I personally have it on a 2004 V8 landcruiser and a 1979 V8 Ford Falcon running a holley efi setup.

Refils have been accurate within 0.5 litres over the 120L fill on the landcruiser, which is a testament to the original MPGuino script.

I am setting up to sell the units, but am after interest or ideas from you guys!

Cheers

Good to see people still updating this as it's way more accurate than OBD units.

I'm interested in updating my Guino.

A full break down of screen options would be useful. Maybe easier posted in a video. Like can I change the l/hr screen to l/100? Looking at it now none of the screens are really useful to me.

I use current litres/100, current trip l/100, voltage (I use LiFe batteries) and speed (I sometimes use 'big speed' on long trips as it's easier to read/more accurate than some old style pre-speed camera speedos).

I particularly dislike DTE being at the top, that's not something you should need to check every time you drive. It belongs at the bottom in smaller text.

Will they all be pre-assembled or will you sell kits? Kits might get more units into people's cars sooner.

Hey mate,

I appreciate the response! yes, far more accurate than OBD units. Cant beat 0.5% accuracy! the pump at the servo is less accurate than these things, so it's almost impossible to be more accurate anyway

Ok so,
Any configuration can be made on the screens. Any helpful ideas would be appreciated.
L/hour turn into L/100kms as soon as speed is detected ;)
The large text screen can display any information on the other screens. Currently there are 5 all up. For some reason I like seeing DTE personally but I can make infinite pages in there with any configuration. Maybe the top 5-6 ideas can remain. It remembers what page (and brightness) is set each time the power is removed so your favourite will always be there when you turn it on.

the only feature that isn't currently in the hardware is the voltage readout. I could add this into a new revision of the board if interest is there.

I am hesitant to offer un assembled boards, as the surface mount ribbon connection is a dam nightmare to hand solder and often produces trouble until done correctly. I would gladly hand them out as kits with a "don't contact me for support" rule :P otherwise full support is of course available for any assembled units

Nice work.

:thumbup: Fords do this factory, but I've not seen it otherwise. It's much better than reading 999 or whatever.

How big is the screen and OA unit?

abbalooga 03-22-2019 05:00 AM

I have voltage readout working :)

Let me know what screens you guys want on each page

abbalooga 03-22-2019 05:00 AM

Also :)

How feasible would it be to custom set fields to order? Or if you're releasing the source code we can change things ourselves -that's probably the ideal senario.

I'd change the triangle of death to something else. Possibly a petrol bowser? It's a bit in your face as it is - if someone borrows your car it might freak them out. What is the variable that controls it (does it learn peak fuel consumption)? Another alternative might be an Ecomodder logo that goes out when you're being naughty.

How is DTE l/100km different from tank 1/100km?

I'd like to see:
Current
Short Trip
Speed

On one of the 3 field screens. I more or less know what I get over a tank so I target 'short trip' always being better that what I got on my last tank. If current is worse than short trip I lift off if I can. Accurate speed is nice as this is going into a car with an analogue speedo (85 Celica).

On one of the detailed screens I'd like:

Speed
Short Trip
DTE or Litres used (kind of one and the same to me)
Tank l/100
Tank ODO
Voltage

Hey Mate,

My code is atrocious and embarrassing :P It's about 6 years of hacking and slaying the original code to make it work.

I can add infinite screens, and I have since added the ability to go back and forward between screens, so you wont need to cycle through them all to get to where you want. My idea is setting up as many pages designed by you guys as you give me. When being used you can leave it on yours and it'll live there. Who knows, you may like some of the others after repeated use

The Tank/DTE trips:
Tank average and ODO is obvious
DTE average and ODO is what the 'current' trip was previously on other mpguinos. It is now used to calculate DTE.. This means it can still be used as 'current' if desired. But will effect the calculation. I did long drives with this unit (Perth to Adelaide, 2600kms) numerous times so DTE was life to me.

The triangle of death is only activated when the Graph goes low or high (set by DTE avg +5L/100).

Peak is impractical due to it being around 300L/100 when you initially move unfortunately.


Perfect ideas for pages mate, I can implement immediately and take a picture. do you mean instant tho? is this what we're talking about

INSTANT
DTE L/100 (current/separate L/100 calculation separate to tank)
SPEED

and

SPEED (medium)
DTE L/100 (medium)
DTE or Litres used (CAN BE EITHER, TANK litres used maybe?) (small)
Tank l/100 (small)
Tank ODO (small)
Voltage (small)
