1227749 ECM

Howdy. I was just perusing Ludis' pages at cruzers and he notes that the 1227749 is a "1227730 w/ one missing quad driver, w/ additional injector driver FET"

Ok, you got me. I'm lazy and I don't want to print and peruse the schematics. I was wondering what outputs are missing as compared to the '730 and what additional outputs are there -- basically once I have converted to the '730 would it be difficult at all to convert to a '749 ?

Reason I ask is that there's 2 bar MAP code for the '749 and I believe that it offers electronic wastegate control -- ideal for a blown third gen ;-)
