Anyone ever run 2 EZ-EFI units on a tunnel ram ? Any problems in street application ?
I saw the guys on Horsepower TV run one of these units and I was curious if it could be used in a twin setup on a tunnel ram without the ECMs fighting each other for "tuning rights" or does FAST offer a harness to hook two throttle bodies to one ECM ? Any info you could throw my way would be greatly appreciated.
2 throttle bodies can be used, harness available or 8 injector manifold with std throttle body can be used. A tunnel ram system should also be useable given the correct sensors. Bigger fuel pumps available for power in xs of 550hp
Yes, two throttle bodies / one ECU. No conflicts. The ECU uses sensors and IAC from the first throttle body. The second one is just used for more fuel and air. It looks cool, too. http://www.compperformancegroupstore...stemEZIEFIKits
There has been a pretty stout dual quad, tunnel ram Corvette running around on the street and the track for well over a year now.
They work just fine with the supplied kit unless you are going to go over 650+ hp. Since you will have way more injector than you need (1200hp worth) you can turn the fuel pressure down to 30 psi and the fuel pump rating goes up with less pressure.
Location: Lake Havasu City AZ.. but mostly travel tuning

I am looking at using 2 of the EZ throttle bodies (even have the same intake as the corvette) but using FAST XFI to control them in a blow through turbo application.
Soon to be EFI
