Tach output for LS2 powered Porsche 997

New to the forums and HP tuners but just received my MPVI2 and ready to play. My project and problem is I did a 24X LS2 swap into my Porsche 997 (see link below). The issue and question I have is what do I need to set the high and low resolutions to in VCM editor to get my tach to work correctly? Currently set at 6 and 6 which obviously does not work. I was reading some other post for 6 cylinder swaps that people were using 3 and 3 on the high and low but thinking the Porsche might be needing to see different settings. Porsche from what I understand is 58X so need to know how to make my 24x look like a 58x for a 6 cylinder tach if that makes any sense.

Anyone with expeience or advise I am ready to give it a try. Thanks
