FITECH EFI 600 Basic and Command center intall with pics, factory tank

I had some issues with the FCC one time it got hot from sitting at idle and shut down on me but once it cooled it hasn't done it again. They did have me lower a fuel psi parameter as well at idle. My unit was one of the first and being a controls programmer I expected bugs. I had a failure of the ecu sending the injector a fuel pulse signal. Causing two whole cylinders to be starved. The truck ran and operated great but was weak and would bog. The system corrected as much as it could only using 3 injectors and got me home. I sent the throttle body back and they confirmed ecu took a dump on that injector. They sent me the new and improved throttle body with the newer bug fixes and larger power wires and fuel pump wire.

All this being said the new system is night and day difference. Starts better runs better. Feels like more hp. And I have not had a single issue. The guys supported me through all the issues and I am very happy. I feel safe to say they have got the bugs fixed now and when I get my 65 mustang fastback ready I will put the same kit on it. I am happy.

Hey Steveo how exactly did you determine you had "a failure of the ecu sending the injector a fuel pulse signal"? Did the controller indicate a fault? I have the same FiTech setup and my truck recently started running a bit rough. I had initially suspected my cheap chinese MSD HEI or a intake manifold leak but after reading your post it got me thinking about my EFI. Thank you.
