do note that if you perform a DATA INIT on this PFC it will return to a normal rb26 PFC
that is, you will loose the settings that make it work as an Rb20 PFC
so the injectors, afm, afm ramp, and maps will go out the window and the base map will be an Rb26 map.
it wont idle with rb26 base map settings and will run like a bucket of junk - so if you do DATA INIT the unit, make sure you note these settings down
