Toyota OBD1 diagnostic port reader, poor man's scanguage

[BillyBob251]

Thanks for the info, I was wondering if it would be possible to get ScanGauge data on an ODB1 vehicle somehow. (In my case, a 1991 Toyota Corolla.)

It looks like if you have a TE2 pin on the diagnostic connector, you have TDCL.
I'll do a cleaner write up when documenting Project E. Currently working on a Bachelor of science in Electrical Engineering so time is tight. I have the material, just no time to track everything down.

hi
looks like a very nice app
but what capacitor is needed? is there a specific one with a range of 1.5-3.3 or can u choose from either 1.5, 2.3, 3.2 etc?

and do you have a video of this thing in operation?

[jimmy6]

and what voltage is the capacitor supposed to be at? 12volts or something else?

You can choose. I just used a random cap that was in the capacitance range but you may want at least a 12V cap (voltage can be higher but not lower).
