hi there..maybe it would be good if you can do a intro on your
ride?
I currently have a SAFC Gen 1 on my ride and it was dyno tuned. I
would say that the improvement for both performance and FC have
improved quite abit. But then again, my car is old thus maybe
allowing more room for the piggyback to improve on it.
However, i have seen the SAFC on various other cars. For example,
the 92 Honda city 1.5 Vtec...with good tuning it really does bring
out more from your engine.
some cars, however, I heard the technology of ECU nowadays have
improved to a point whereby they are able to offset any piggyback
settings. I do not know this for sure but these are some
examples.
For Subarus TS and Rexes, i heard that within a month or so the ECU
will have fully offset any SAFC settings. Thus for the SAFC to
continue working, you would have to reset your ECU ideally, every
week.
And reading from the Vios forum. The members there think that the
SAFC Gen 1 does not work well on their car and only the SAFC Gen 2
works well.
Lastly, a humble opinion. every car was designed for a particular
market and has its own limits so dont expect TOO much of a
performance improvement should your car not be designed so.
