Hello there,
Recently installed a Whipple on my Cobra along with return style fuel system using 60# Siemens Deka injectors. The MAF transfer function was dialed in pretty decently last year using the stock 39# injectors. FRPS was kept and base fuel pressure was set at 39psi and pressure was verified to hold through the whole RPM range.
Thing that bugs me is the car goes way rich at high load and I don't know if it's due to incorrect injector slopes or the fact that my new NGK AFX wideband is more accurate than my Dynoject WBC... How does one verify the accuracy of injectors slopes ? I'd hate to mess with the transfer function only to realize later that it was an injector characteristic issue.
Thanks !!
Alex
