this may not sound like a big deal but you can bet theres now going to be a ton of trickle down technology benefits, for us hot rod types, as theres now going to be a TON of money dumped into intake design and throttle body and injector research for high rpm engines that was never before available, remember these guys think nothing of dumping a $100k into tweaking components to gain advantages and theres dozens of teams and hundreds of sharp minds that will be working on this that were never involved before

After sales have started with the new Holley EFI, and seeing most people don't read instructions, thought I'd comment on some mistakes I'm seeing repeated.
1) Mounting of hall effect sensor for 60-2 trigger wheel. Although the "head" of the sensor is large, the actual sensing portion is small. A hall effect sensor must be lined up with the "teeth" of the trigger wheel to properly read. If the axial alignment or sensor air gap is too much, you will not get a good reading, or the reading will degrade at higher RPM. So make sure the center of the sensor is axially aligned withing about +/-.050" at WORST and get the air gap around .030".
2) ECU main power and ground. The instructions clearly show power and ground going directly to the battery for ECU main power. Do this. DO NOT run power or ground to a "stud" that also supplies power or ground to noisy/dirty things like MSD systems, electic fans, etc. Always isolate dirty and clean powered components.
Don't be sloppy with EFI installs. It will cause you problems.
