I'll have to go back through this thread, but is is almost exactly what I was going to start building for myself.
I have a TunerViewII currently, but the guy that makes them is not being so supportive of the GM and Ford side, so I'm looking at other ways to get what I want out of a display.
I was planning to start with an Arduino, and get the basics working, then add features as I was able to, and my ultimate plan was to end up with a display that would also log to an SD card.
Depending on price I'd be interested in getting one of these, if it will work with USDM code, which it sounds like it should.
Will this support multiple displays? That is one reason I was looking at starting with an Arduino, I have seen up to 4 2x24 displays connected to one Arduino. I was hoping to be able to end up with 2 or 3 4x24 or 4x16 displays in the end, using "large digits" on a couple of the slave displays.
Anyway to remote mount the SD card slot? Once I get a display that does what I want, I want to mount the display in the gauge cluster (probably replace my tach, which is another reason to need multiple displays), and then have the SD card slot either in the bottom of that cluster/gauge or somewhere easily accessible.
Personally, I'm not interested in flashing the ECM through the dispaly, while it sounds like a cool feature, I don't know if it would work with an Ostrich 2.0 or not, and I usually prefer to tune on my laptop, in real time, anyway.
Looks good, I'll go back through and read for details since some of my other questions might have been answered already.
