rb20det AEM series 2 ( 6620 ) problems

[Black_label_240sx]

Hello all
I have a series 2 AEM ems, ( 6620 ) box, AEM only provides the start up calibrations for the 25/26
so, how would I go about converting a map setup to maf ( as both 25 and 26 calibrations are map ) and for injector phasing going from rb25 to rb20, what do I set the values to, or what would I do to find out what values they need to be at.

Second
Installed the AEM CAS wheel, won't start, heard alot of other people are having problems getting rb's to fire using the AEM CAS wheel

Where to start ?
thANKS !

ALighty, update
since no one had any input, heres what I found

AEM series 2 ( 6620 box ) doesn't support MAF setups for the rb series -per aem techs
Even though there are multiple mafs/windows to use with the AEM tuner for the rb series, none of them are programmed to work

AEM also doesn't have any rb20det start up calibrations, which wasn't the end of the world since I found some series 1 aem maps to use as a reference, and some other rb20 owners from AEM's forums made a few base maps I could reference.

So now I proceed to buy a MAP bar sensor. Fools errand but I'll ask
any input on what type of MAP bar to use, 5,3 etc ?
