Maybe I missed it, but would the alarm/buzzer work for any and all guages, even if they are not being displayed? So If the ECT reaches a preset temp the buzzer sounds and the ect is diplayed at the same time. And who can set when the buzzer goes off? Would the buyer have to tell you what he/she wants at the time of purchase?

Also... i would personally love a toned down version of the kit that is nothing more than you'd need to tie it to an aurdino (or similar). Even if you don't want to make the shield, just the interface and some documentation would kick ***.

I know you spent a lot of time reversing this yourself, so i'd completely understand if you weren't interested in sharing the information. I'd be just as likely to buy either option, personally, i'd just love the ability to implement custom displays.

I will look into opening up the spec later...

I tap into these, but not at the OBD2 connector. Rather I tap near the tire pressure system, which is close to the LCD display.

So the short answer is yes, this is OBD2 based, but I don't take up the OBD2 port, so the install is invisible if for example you were to get your emissions tested.
