Another "Is Fuel Injection a Worthwhile Upgrade?" Question
EFI is for sure not for everybody. The big problems as I see them:
(Bear in mind the auto manufacturers have spent millions? billions? of dollars "getting it right.")
1...There are SO many variables in installations, including different pumps/ fuel systems, and improperly sized regulators and return systems
2...Different injectors, senders, and sensors, especially with "home built" systems such as Megasquirt
3...Even in the case of "packaged" systems such as Holley sniper or FItech, you have the problems with electrical interference (EMI/ RFI) which is a LOADED boat. This is even more complicated because of very high power ignition systems and alternators.
You MUST be careful with wiring / routing, and often should add properly shielded / protected wiring. It is a well known fact that ignition systems such as MSD can cause electrical interference. In fact, MSD if improperly wired CAN TRIGGER ITSELF. The high power radiating from plug wires can be induced into the pickup/ trigger wiring and re-trigger the MSD!!! No EFI needed for that problem!!!
4...For certain programming the system is a learning curve. I barely know what to do, and certainly would not go digging around--at this point--in another person's system.
They aren't for everybody.
