Request to open ecus and throttle bodies
#26330 from JEREMY HILL · Not recommended · Minutes (2019-03 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. The
original intent of the FB rules was to allow the fuel injection system to be unrestricted except
for a requirement of stock throttle bodies from a fuel injected engine (see GCR section
9.1.1.G.4.E) and to prohibit the use of stand-alone aftermarket ECUs (see GCR section
9.1.1.G.4.C). Any intent to require the throttle bodies and ECU to be year-matched to the
engine would have been specifically noted in the rules, which contain no such requirement.
