  View original topic: DIY Arduino ECU comunicating with Iphone
sarahconnors Mon Sep 21, 2015 1:18 am

Hi,
We are currently developping an ECU with ARDUINO / ford edis.
This ECU will replace all the f...ing ignition system.

It could be assembled without any electronic knowledge. All part will be easy to buy and CHEAP. ALL source will be published and public

ECU could be stand alone or managed by Iphone (Apps) or computer (USB).

Right now, it is not a wishe anymore. IT WORKS !!!

ECU Functionality is :
- It will allow multiple curve (5 curves). DONE
- Each MAp will Allow 17 X 23 ignition curve (kpa / RPM) DONE
- Allow multi sparking DONE
- Manage MAP sensor ( 0 - 3 bar for atmospheric and turbo engine) DONE
- ECU comunicate with I phone through bluetooth DONE
- Cold start improvement DONE

Future improvement will be :
- Knocking sensor Work in progress
- Iphone Apps functinality (in progress):
- display RPM/ MAP pressure on Iphone
- manage/ modifiy curve on Iphone
- send curve to ECU on Iphone

Right now, ECU is working well on my '63 Bus. I did a big trip this summer with it in france. It improved drivability a lot !

We are still testing/improve it. Now we are working on Iphone Apps

Great work. I love building with arduino. I've followed some discussions where people have asked about doing electronic fuel injection using arduino, but I've never seen anyone see it through. Any thoughts on whether arduino has the capability and whether you would be up to taking on such a project?

Hi,
Ignition was the first step, and it is working.
Injection is the next step. Basicaly it is the same approach you need a map and an injection point.

I m sure Arduino can manage this in parrallel with ignition.
Right now, with ignition control arduino is doing nothing 80% of the time !

Why Iphone? You're limiting yourself to less than half the market.

Northof49 Mon Sep 21, 2015 9:48 am

I would think that what you have learned from controlling spark based on rpms and map readings, the leap to fuel control would be a logical progression. Thanks for developing this and posting about. Keep us up to date on your work.

yes we learned a lot on how to manage real time application.
we did it on iphone first because it is simpliest than the rest and because the co author knows iphone( i m more involved on Ecu)

i hope that some people will be interrested by this subject and could help

Sorry I am not smart enough to contribute. I've done some wifi based remote monitoring and autonomous robot stuff, but highly derivative from others. I mostly piece together the best parts of other peoples ideas I like.

sarahconnors Mon Sep 21, 2015 11:47 am

that s exactly what I did. Put best parts of others...
ford edis + arduino + bluetooth

and try to coordinate all together...

Awesome project. I love Arduino, I'd love to see this make it.

I'm prototyping a computer system for ACVWs to monitor system vitals and info, and it will display on a small LCD/VFD a la the VW MFD/FIS clusters from later generations using an Arduino Uno. Versatile little devices, they are...

Android has huge market share and is less finicky about software and connect-ability...

So, how's your MSDroid install coming along?

Dale M. Mon Sep 21, 2015 6:30 pm

Project died in its infancy when I sold race car it was intended for....

Maybe if new project comes along I will resitate EFI project....

injection is now running well since january !!
ECU has now some interesting functionality like "self learning" or idle regulator

source code are on github : https://github.com/sarahconnors1/combiduino

Cool! Which Arduino is supported? Will an UNO work? What hardware does it need?

sarahconnors Fri May 20, 2016 12:20 pm

basicaly you need an arduino mega, 1 EDIS ford, 1 mosfet card,1 map sensor
the most expensive part is the aluminium box..

but the beautiful thing is you can do it without any soldering!! it is just pure assembly
