i dont see anything in the manual , how and what can i use to setup a 2 step rev limiter

TIA

i thought the SDS computer has only one revlimiter and that is a fuel cutoff. it's the MSD DIS2 box that has a 2 step revlimiter that are soft electrical cutoffs.

the instal instructions are here (p 15):

it says the SDS box must be specially configured to mate with the MSD DIS2 box.

this is from the SDS site:

Q. Is the F system compatible with 2 step rev limiters? 04/07/99

A. By fitting an MSD DIS and MSD PN 8870 coil spacers, you can have this capability on an F system.
