ECM bench bits

[Bruce]

If your seriously think about playing with code for your car, you really
need to run the changes first in a way that you can monitor them and make
sure they are relatively safe before taking to the open road.

Hence the need for an ecm bench.

Just to make life a little easier, and to keep it looking neat an clean,
there are a few little dodads that will help.

Velleman-kits has a Signal generator #MK105 and a sound generator #MK113,
you can play with component values on the caps for the 555 and add a
variable resistor to change the freq out put.  You need these for the RPM
input, VSS  input

then to get a cam synch you can use a Rainbow kit CL-1 Light chaser to get a
divide by 6 for the cam synch.

Add some sort of scan tool, and you can drive your ecm atta 150 MPH on your
kitchen table for hours.

Oh, and they have a stepper motor kit that you can slow down to use in IAC
diagnostics.
