Q. How does the boost portion of ghettodyne 2.2.1 work?
A. This release includes the "GeorgeHack" or digital MAP-hack bin. This bin preserves the stock 17x15 table size present in the stock ECU but changes the range of the stock table by digital scaling the MAP signal by 5/8, so you can map just about to the end of the stock MAP sensor's range (10psi). GhettoDyne 2.2.1 is functionally very similar to using a AFC or SMIC or LMN7803 or whatever the **** you use to cut the map voltage.
