In case anyone wants to know...there's already another product on the market similar to this and with some of the issues already solved like alarms, bigger screen, etc.

Sizes are:
Small LCD (Small LCD)
Active display (LCD size): 3.74 " x 0.70"
Large LCD (Big LCD)
Active display (LCD size): 4.92 " x 1.69"
Huge LCD (Huge LCD)
Active display (LCD size): 5.78 " x 2:55"
These are some of the parameters that can be tracked also:
Oil pressure (oilp)
Oil temperature (oilt)
Intake air temperature (IAT)
Intercooler Temperature (ICT)
Intercooler Efficiency% (ICE) (Input and output should be measured together)
Water temperature (Wts-Ector)
RPM (RPM)
Exhaust temperature (EGT)
Air-fuel wideband (Afar)
Turbo Boost-Vacuum (Map)
The throttle potentiometer (TPS)
Injector Duty (Duty)
Volt battery (Batt)
Outside temperature (outter)
Gas pressure (fuelp)
Serial output (Datalog)
Speedometer (Speed)
Fuel level
It does use sensors vs obdii so there will have to be ports available to install them.
I am not trying to knock the OP for his idea but I just wanted to let others know about it if they needed something similar in a smaller timespan that already can do what this product will (eventually) do.
