Question
#1. If I change exhaust on
my fuel injected Harley, will I need to recalibrate my computer (ECM)?
Quick answer: Yes. If you
change any component in the ignition, fuel/intake, or exhaust system, it
will alter how the bike responds to computer parameters, set by the evil
meanies at the E.P.A.
Rarely are changes subtle enough not
to be noticed. So to optimize economy, torque and horsepower, an
adjustable programmer is necessary, along with dyno time. (ours is a state
of the art dynojet 250i with eddy current brake and air/fuel ratio monitor.)
Multiple changes always mean dyno time and an adjustable programmer for
the best results.
