Is this the thread you're referring to?

"FAST EZ EFI 2.0 the elephant in the room"

If so I don't get the "long" statement. Like many of these threads this one has many posters that aren't using the product referenced. They merely state what they are using. If you took away those posts this would be a one page thread.

Finally like most of the efi issues I've dealt with almost all are self inflicted install problems. In this case the use of far too large injectors for the application. The other big no no is running efi and ignition boxes too close to each other. Or the good one. Separating them only to bundle the harnesses together at some point. DOH! The pretty much negates the separation doesn't it???


Other typical install issues are caused by shared vacuum source to the MAP sensor. Or the O2 sensor installed too far aft of the collector. Or bad welding of the bung allowing air to be pulled into the exhaust. I've also seen box stock MSD distributors installed without any adjustment of the timing curve or timing stops. Another issue I've found is the power source to the ECU. The battery is used as a "line conditioner" for these systems. I know the 1.0 systems ECU even come with a orange "toe tag" saying to connect only to the battery - yet people discard that info and try to run off some other point in their power system. All of these seem relatively minor things to the installer but they are not minor at all. Then in an attempt to rectify the running issues they only blame the system because they can't seem to get the system to be perfect via tuning. Kinda like blaming a miss on the carb.... they continue to attempt to tune the miss out with the carb
when it's really a fouled plug. LOL

Not trying to defend this particular 2.0 system. But the usual issues are usually NOT the hardware / software. Whether it's FAST EZ or XFI or someone else's brand.
