Making a Vss signal

[Ezekiel Holliday]

I can tell you if you know the number of pulses per mile and the speed that you want the computer to think it is going.

]Hi everyone
I'm making a 555 timing circuit to fool my fuel injection system to think that its in the truck when its really on the dyno.
Bruce Plecan  instructed me to get a 555 timing chip which I did and a 7805 voltage regulator. Has any one used these before (I know bruce has, I hope he's OK), I need to figure out what caps and restitors to use to get the frequecy right. Also does anyone know how many pulses per mile the Syclone (7749) computer uses. Last question do I use the DRAC module as well?
Thanks
