Dave ---
Wasn't meant to be a sales pitch! But I can tell you -- after messing with EFI stuff for 10+ years now... this stuff is FANTASTIC. Honestly. A lot of EFI "messes" are newbie install issues... and some of the problems are "paying for the tuner to learn and go to school on your motor".
With this EZ EFI from FAST... it was so simple a caveman could do it. Not sure how a guy that can read - could mess it up. Half the wiring my Accel Gen 7 has/had.... Super easy instructions... and I'm running an 8 stack -- which is supposed to be "messy" to tune. I can tell you from experience -- it IS NOT messy to tune... and it's even easier using this new "self learning" system. The motor NEVER ran better... EVER. Once the throttle bodies were dialed in -- which took a few minutes to get them right on the money... it was all "sit back and watch and have fun".
The key is -- a good vacuum signal to the MAP sensor... (in other words -- no T's and nothing else running off that line!)... No header leaks (which introduce air causing the O2 sensor to read wrong).... Having a good fuel pump and pressure regulator. Good ground and power source to the ECM... no messing around here! They've got to be GOOD. AND #1 ---- a CLEAN tach signal. They recommend coming right off the MSD box Tach signal. Which is the way I ran it. Also -- DO NOT locate the ECM near/next to the MSD box! The signal can cause interference.
Fire it off -- and she'll start humming.
I have a Edelbrock Carb intake for my LS6 that I'm going to run in my '37 Ford... was going to just keep it super simple... NOW I'm going to run an 8 stack on that LS6 and this EZ EFI...
