My newly purchased 93 wrx import has an fcon v and after having a dig around noticed a prova sticker on ecu, does this mean that the prova upgrade is no longer being used as the maps are now coming from fcon v?Also I fail to see the point of the fcon unit as nobody can get the software to change maps and I dont think its a cheap unit either!Will be swapping out for dta or megasquirt I think!......Anyone recomend a decentdump valve?
