ECM Test Bench

[RobertISaar]

Just a variable 10K resistor (pot), that is manually adjusted.

For a simple 1 wire O2 sensor I use an LM317 DC voltage regulator for 0vdc - 1vdc. http://www.national.com/mpf/LM/LM317.html#Overview" onclick="window.open(this.href);return false;

neither of these options would make the O2 swing though.... just provide an static mV value until manually adjusted.

JimStim does narrow and wide band.

and i'm piecing this together bit by bit, since it will be incredibly cheaper and will allow me to tailor the bench specifically to the target ECM's capabilities.
