Jim Ahlman speedo recal

I picked up a Jim Ahlman recal unit. I have the directions. It is the one line, 9 pin unit.

I've followed the directions exactly, but the speedo is still high. Then I deviated from the instructions, and I made it read a little less high. The instructions say to leave pin 3 at off if speedo reads high. I actually turned it on in the sequence, and it moved the speed down. But I had to use a full 30% value to move it just a bit.

Anyone have experience with this unit? Or different directions? I must be doing something wrong. But it seems straight forward.
