This means starting with engine displacement, idle rpm, rev limit, fuel pressure, and resetting the throttle position sensor (TPS) calibration. This essentially purges the computerвЂ™s memory of the previous tuning changes. The next item to try is to run back through the initial calibration process again.

DonвЂ™t be afraid to lengthen either or both power and ground leads if that what it takes to plumb them directly to the battery. This allows the battery also to operate like a giant voltage spike suppressor which allows the electronic side of the system to operate normally. So it is essential that the main power and ground leads go directly to the battery. This leaves very little room for error with regard to proper grounds. All EFI systemsoperate on electrical signals from sensors that normally operate on a 0-5-volt scale. The first thing to emphasize is that the main power and ground wires are in fact connected directly to the battery. LetвЂ™s see if we can focus in on your problem.

But there are a couple of areas where it is essential that the initial installation be performed properly and then attention to details can make all the difference. Jeff Smith: WeвЂ™ve installed several of these new-generation, self-learning fuel injection systems and they seem to work very well.

Attending to the details will make a big difference in how the system works. This is an EZ-EFI throttle body on a big-block Chevy we did a couple of years ago that worked out very well.
