Monitoring VX Engine/Sensors/ECU
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 More info https://www.superhonda.com/forum/f55/...inouts-217405/And here: https://technet.ff-squad.com/wiring.obd1.htm https://technet.ff-squad.com/wiring/obd1/plugs2.jpg https://technet.ff-squad.com/wiring/o...schematics.gif Thanks Ross |
A PIC microcontroller and associated circuitry could handle the vast majority of those signals no problem. It would obviously be a very DIY project of course.
Other than that... some interface with lots of digital (on off) inputs for Vtec, VSS, fuel, etc, and analog inputs for MAP, throttle, etc. I suspect you'll still have to write your own software to make it good for much. I'd do it, but I currently am seeking employment so I can buy my CRX shell... |
I'm hoping to find something more readily usable. I saw there is a MPGUINO MPG Gauge based on OpenGauge source and Arduino platform.

I think there are several commercial solutions for OBD-II but I'm yet to see anything for Honda OBD-I. Does it exist? |
There are several that work with obd-1 honda ECUs, but none that I know of that work with the VX ECU which allow you to keep all the functions of it.
Mostly these software programs are meant to help you get more performance out of the engine. Check out https://forum.pgmfi.org/ or honda-tech.com, or homemadeturbo.com for more info. |
