GPS performance meter on in-car PC
Hi there, great site youve got here.
Im planning to build my own incar PC, ive got most of it straight in my head but im struggeling on how to add the function of a performance meter to my system for- 0-60 timing, 30-50 timing etc, Quartre mile timing, force and power estimations and so on.
Will i need a GPS reciever with a higher than standard sample rate?
Is there any software currently available for this. If not what do i do as i only have limited programming skills.
I have also been considering linking the system to the cars ECU for live mapping. I would consider upgrading my ECU for this, has anyone had any experience with this and does anyone know of any copmataible aftermarket ECUs
Another option is connecting the system to the cars air, temp, oil sensors like data logging systems currently avaiblable, does anyone know how this could be done on the go.
I also have one or two other questions.
My car-Pc will be based on a laptop which has a pretty poor sound card. Are there any external sound cards available with phono line outs so that i can connect to my current amplifiers.
Any suggestions for other software would be greatly appreciated, like a good sat nav program with gps locations of speed cameras.
Seen as ive asked somany questions i will describe what i plan to do incase you are interested.
The laptop will be hidden in the dash and its power button will be linked to the ignition so that it comes on when the car is started with a manual overide of course.
The system will mainly be controlled by an 8" touch screen LCD built into the dash but the laptops own screen will disconnected from the laptop and hidden in the passenger side of the dash.
To the laptop i will add:
A wi-fi pcmcia card to allow remote access updates and transfers from my home pc
A GPS reciever for nav, speed cam detection, performance meter
DAB radio reciver
High quality external sound card
Blue tooth dongle for hands free mobile phone functions
Usb hub built in to the dash for any other connections
The side of the laptop will be flush with the dash so the dvd player is accesible. As i already have the laptop lieing arround costs ontop of its value are estimated at £260 which seems fair considering all the functions.
