Monitoring VX Engine/Sensors/ECU

[djenyc]

I'm interested in monitoring engine running condition for the purpose of diagnostics and better understanding of what is going on under the hood.

I know I can use multi-meters or borrow oscilloscope, but it would get cumbersome to monitor more than a couple sensors/solenoids. Is there an interface board and software that I can use with a laptop? This way I'd have a nice real-time display with data logging/post processing capabilities, hopefully on the cheap

It looks like by tapping in to ECU wiring I can monitor:
MAP Sensor
Throttle Angle Sensor
VTEC Solenoid
Engine Coolant Temperature Sensor
O2 Sensor and A/F ratio
Intake air temperature sensor
Injector openings
IACV Solenoid engagement
EGR Solenoid engagement
EGR Valve Lift Sensor
Fuel pump engagement
Radiator Fan engagement
A/C Compressor Clutch engagement
EVAP Purge solenoid engagement
Crank position sensor
Knock sensor
Alternator Charging Signal
Electric Load Detector
