<< 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.
