im in the prosses of turning a cf-27 toughbook into an automotive scan tool. i have the software and the cable for the multiple scan tool software packages i am installing. that part is simple.
BUT even with the multiple programs i am installing i still need atleist 6 inputs that monitor voltage and resistances for those certain vehicles that dont have a data link connector, or that are uncomatable with the software i have. plus for the vehicles that "are" compatible with the software, it could be used in cunjunction so that i can monitor what the ecu is seeing and what the sensor is actualy sending. this would out do the pro scan tools do to the user frendly interface of a pc.
my question is what would be the simplest way to go about doing this?
my options are:
(1) buy multiple $10-$20 simple digital volt ohm meters, gut them and find a way to make the communicate with a rs232 or even usb interface with seperate channels.
(2) start from scratch and build my own pcb and circuit.
(3) spend over $1000 on a rs232 dvom module that has only one or two signal monitors. this would almost be useless to me looking at the fact that i only have $200 into the scan tool so far. id ductape 6 meters together befor i spent $1000. i dont even pay that much for the vehicles i drive.
any ideas?
