here is what you want to know 1) It supports Dual MAFS (works the same was the AFC for this) 2) You can run a single MAF and when it goes to 4.5V you can have the MAP sensor (optional) start taking over using its own table 3) You can use a bigger MAF and scale the data for the ECU. 4) You can change MAF ration by +/- 20% this what the AFC does. And you can do this on 16x16 table (alot more points of adjustment) 5) It can increase the injector flow by upto 100% so can have an ECU thats programmed for 370cc injectors and replace the injectosr with 740cc injectors. Or you can tell the E-Manage you have only 700cc injectosr when really have 720cc incase you want to play it safe 6) You can ignition changes based on RPM and LOAD thats a 16x16 table.
Basically its a fancy AFC+ITC piggy back. Seems to be a good deal.
