GhettoDyne 2.2.1 MiniFAQ v.01
Q. What ECUs will ghettodyne work with as a one-chip drop in solution?
A. 90-91 PM6, 90-91 PR4, 90-91 PM7, 90-91 PS9, 90-91 PR5, 90+ PP5 (rover with Cat) The key here is that the ECU has a 256k external EPROM.
Q. Are there other ECUs that ghettodyne will work with?
A. 88-91 PM8, 88-89 PM6, 88-89 PM7, 88-89 PG7, 88-89 (nocat) PP5 (and maybe others) will work fine too with an adapter board. This is much more of a pain in the ass - see pgmfi if you care enough.
Q. Does ghettodyne support ______ ECU not listed above, like my P28 or P72?
A. No.
Q. Will ghettodyne ever support ______ ECU not listed above, like my P28 or P72?
A. Probably not.
Q. Ghettodyne doesn't run right it gives me some dll or ocx error!
A. See

Q. Does Ghettodyne support logging?
A. The GhettoTunes have provisions for datalogging at 9600 baud. A companion program, ECUControl, can support a limited amount of datalogging. It is a work in progress (i.e. NOT FINISHED AND NOT TOTALLY WORKING) so don't throw a shit fit if it isn't logging your favorite sensor.
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 fuck you use to cut the map voltage.
Q. Why use GhettoDyne 2.2.1 instead of a AFC or other hardware-based maphack?
A. Easy. Two big reasons: 1: A chip and some software is a lot cheaper than an AFC or SMC (but maybe not cheaper than a 7803) 2: You can tune timing with ghettodyne 2.2.1 so that the car is not excessively advanced under NA conditions and the desired amount of timing retard under boost is present.
