Well ur PFC have 9 fuel maps then the gcc gives u a few set rpm + or- no timing ajustments at all , the kit I'm looking at gives u 16x16 boxs to ajust for the fuel map 12x12 map on the timing , idle ajustments , fuel cut were u want it , ajustable rev limtter fuel or spark or both , target afr if u have a wideband , knock input , boost control at a small cost , launch control at a small cost , out puts for water injection if needed , shift lights if needed , and more u can change to coil packs if u needed the list gos on and on tbh and with a base map on thr should be fun for the diy tuner to tune
