Scanmaster II?

[Wastegate]

On the scanmaster reference sheet it says you can get
injector pulse width and Spark advance
with a special prom.
Do i need/want this for a good tune?
I like the idea of having this anyone know where or how i can
get this to work?

You need the "Fast Update Code" programmed into your chip to get those features:

Most chip burners can add that into your chip. Who's chip are you using? Also, what version of Scanmaster II do you have (what number shows up on power-up of the unit?). Should show 2.0 or 2.1.
