Anyone using the SVO Motorsport rpm extender, please help.

I just got my motorsport rpm extender today. It obviously was used, so I did not get the instuctions. Can anyone that has one, or has used on, tell me how to adjust it. It has two adjustments, A/F and RMP, and they both have a stetting that goes 0-2-4-6-8-A-C-E. For example, if I set the arrow on both nobs to 8, what setting is that. Maybe someone that still has the instuctions on theirs can scan them and email them to me. I know that this may be a stupid question, because this is old school technology, but it beats me having to screw with computer programing. Thanks for the help.

Thanks for that info blue coupe. I have a msd 6 al, so I just want to get the computer rev limiter out of the picture, and I have a 331 with AFR 185s, comp cam and I am installing a trick flow R intake, it should make power to 6250 with no problem, and I want to be able to adjust the A/F. Thanks for the help.
