Using P5 for GM MAF input

[dwafford]

The manual says P5 can be used for GM frequency MAF input, and is suitable because it can handle the high frequencies. But it also says that if this is done, hardware changes must be made to the MS3 - but I can't find anyplace that explains what changes must be made. I can't use P4, because I'm using it for my Optispark high res output. Thanks for any help.
