I have been using the old dos based Accel DFI for about 5 years now and am thinking of upgrading to either FAST or Gen VII soon. I currently use the nitrous function and love it, it works great.

Does Gen VII or FAST have a progressive nitrous control?

 

Yes it can delay the fuel or nos noids also! Built in wot,A/F,rpm switches! And much much more! I have the old Accel and the new one!

 

Gen VII does not act asa progressive controller. It is a delay and many other functions, but not a progressive.
