I agree. I think your project is great, and the ecu independent and extended sensor reading is also a very good point.
I only wanted to inform you that your hardware and software can easily extended with an OBD reader using only a serial port of the Arduino to get information from the ECU.
normally yes, but i believe the td5 has a propriety diagnostic protocol no ?Quote:

That's right, the TD5 doesn't conform to OBD standards
just finished installing 'new' modded header tank, and the float switch works. how long it will last i will find out.
i couldnt bring the engine up to temp and pressure as i didnt realise on the header tank i just installed there is a extra drain outlet that i need to block up first...
so just a reminder all the source code is still available here: with photos and description

some day i hope to design a pcb and housing to finish it off.
Great work. I want something like this for my Land Rovers, but it would also be great for my boat to mesure EGT and boost.
Haven't done anything with Arduino yet, so I will have to start studying first I guess.
Any plans for EGT and boost readouts?
arduino is very easy and affordable. order a 'nano' or two off ebaey, thats what i use for this as its enough.
EGT, Boost and any other sensor would be possible too, not that i have immediate plans for them it would be easy enough done though
I'm working on an expanded version of this. Currently running an Arduino Due as a display driver to output a 256 colour VGA signal to a 7inch colour monitor left over from an old carpc project. As the VGA system is so CPU intensive, I'm using anther arduino uno to measure everything and send it all to the display driver via serial.
There isn't much limit as to what you can measure - it's getting the maths right that's the tricky part
Just finished fitting one of these common oil pressure senders along with a 1/8" 27 NPT T piece to the engine: all up only about $40 off ebay australia !
now i just have to code support for it.
the sender is 0 - 10Bar translating to 3 - 160 R (ohms)

Started reading this the other day very good ideas here and something I am interested in. Just spent the last 20minutes trying to find it again to continue reading so now with a comment its much easier to find.
