[urq] ABT ignitionbox

[Paul Ahvenainen]

If anyone has an extra ABT or similar "chip" that will work with my otherwise stock 83WX, I would be interested.

Thanks:  Paul Ahvenainen

Yes the stock computer can be chipped as I have one from my old 10v. And
some of the things are a Fast Start and Increased boost without running lean
Fast Start makes it so when you are starting the car it doesn't have to
crank over so many times before it fires up, Just hit the key for 1 second
and it fires up!
The addition of a zener diode will make it run lean at top end without
fuel distributor mods!
