Thank you SeeThruHead and redondoaveb for the suggestions and ideas.
I appreciate it!
SeeThruHead:
A display that is "inspired by Motec" could be done down the road. It has a really nice layout!
Also, I have looked into round LCDs displays to replace all of the 370z triple gauges, with any data item you would like.
As I understand it, the factory triple gauges are difficult to remove and installing LCD gauges would not be easy. My first preference is "plug and play" solution as it greatly reduces installation errors. From what I have seen, many don't seem to understand electricity/proper wiring and do silly things.
Right now I need to focus on getting out what I have been working on for the last year: the Bluetooth gauges for Oil pressure, diff oil temp and other CAN bus data for the G37. Since I have easy access to one (my car in the garage), the LCD enclosure is easier to model and to test.
Speaking of testing, we have developed a new add on for the G37.
A manual transmission Gear Position Indicator in the FACTORY cluster:

This will be an option in the LCD gauges / mini-dash, or a lower cost stand alone device the size of a small ELM327 and it is plug and play via the OBD port.
I have been driving standard for 40+ years and don't need to know what gear I am in.... However, I sure enjoy seeing the gear number in the factory display!!
