So uh, does the FI work or not on this pig? Didn't realize it's been THREE YEARS since you've posted to this thread
Oh, hey. Sure, it works. There is a stumble when I go from closed throttle to sudden throttle tip-in that I haven't solved (because, frankly, I've never researched to learn how). But in all other aspects, it works perfectly. Even with my tip-in issue, it has far fewer "quirks" than the carburetor ever did. I'm happy with it.
For those considering a similar TBI-style EFI conversion--of any brand--I will tell you this: your success will be entirely determined by two things: properly installing the (few) wires required, and building a proper fuel system. For the latter, I merely imitated the OEM factory setup and installed an in-tank high pressure pump, and this winning strategy has worked flawlessly. As for the wiring, I made sure to follow the directions and use appropriate connections for every wire (especially the one that must be hot during key on
and cranking).
Why do I mention this? Because Mike put the same system on his El Camino and kept having problems with starting his car. On a hunch, I told him to look at the wire mentioned above, but he shrugged off this suggestion because he felt his wiring was not to blame. He finally got so frustrated that he removed the FiTech and dropped back to a carb. I took his system home, removed my TBI unit itself but
not my wiring harness, installed his TBI unit onto my intake manifold, and plugged it in to my wiring. It started right up and worked perfectly for months. Later, I swapped mine back on my car and gave his back to him.
Proper wiring is crucial.
