I have been doing a large amount of research lately.
my goal is 7-8 psi small turbo super reliable DD-able on a budget
and it seems like all the turbo chips out there say you need a rrfpr
in order to make fuel come out right. why?
Unless I have missed something ecu chips for a 173 can change
the fuel map. So why would chip companies not test and tune
their chips so as to make rrfpr's unneeded? that would cut costs
for us and make their turbo chips very popular. Also would that not
be a more accurate means of controlling fuel?
even if chips cannot change the fuel map would you not then need
a AFC + wideband in order to know how to change the rrfpr?
I know that MS2 is a better overall option but I am wanting to go with
something pretuned, even if very conservatively, so that i dont have to
do a large amount of trial and error and all that extra work at first.
