[QUOTE="RedVenom48, post: 15653577, member: 166576"] How does fuel pump control work in return system when using the factory ECU? Ive decided the next major mod for my Shelby will be a conversion to a return style fuel system to run E85 at the track and other performance oriented times. Im looking at saving for this kit here from Lethal Performance: [URL]http://www.lethalperformance.com/lethal-performance-07-2012-shelby-gt500-2000rwhp-triple-pump-return-style-fuel-system.html[/URL] The fuel pumps are not pulse width modulated like in the factory returnless system. The kit includes wiring to splice into the harness for the FPDMs, but the return fuel pumps are constant flow. How does the Ford ECU not freak out when a return style setup and pumps are installed? Do the tuners turn off certain codes in the ECU when running a return system? Does the ECU not know any better as long as its programmed A/F parameters are met? [/QUOTE]
