Time for a gear swap!

[BattyV6]

Well I think the time has come to do a gear swap. I have a open diff. and 3.23's as of now, and I am going to go with a Zexel LSD and 3.73's. I've got a M5, so shift points aren't a problem. What is a problem, obviously, is the speedo. Since SLP discontinued their Speedo Recalibrator, what should I use 'cause I won't do the swap if the speedo's off.
Will this thing work?

I heard that the SLP unit worked on M5's, is this correct? If it is and if I could maybe get a used one, would it work?

Thanks for any help you guys (and girls) can give me.

Looks like that would work, be sure though I would call and ask just to double check.

I use the Jet SCU2000. Went through the carwash, damn thing doesnt work now. I'll let everybody know how it works after it comes back from the warranty repair.
