Holley HP EFI wiring

..... I run the Holley Dominator in my heap ... I had a 4L60E in it when I replaced the HP with the Dominator ... TH400 now so the trans control is moot ... mine is sequential fuel injection with LS coils ... I use a FAST dual synch distributor for cam , crank signals and to drive the oil pump ... it freaks everyone out when they think they're looking at an LS swap then see a dizzy with no spark plug wires ... I eliminated the A/C and put a 2nd alternator on the brkt to power the Holley ECM ... I primarily drag race the car but it still goes to car events ..... the OEM ECM is still in the car ... the Holley runs all engine controls ... I have a custom dash with analog gauges so I could probably toss the ECM but out of sight , etc. ... Self tuning works really well , it gets tricky when you run a cam with more than 245* duration , overlap puts a lot of extra Oxygen into the exhaust ... I'm still tuning , but the car is getting very consistent at the track ... if I leave the tune alone , I'm within .03 on consecutive passes ... That's actually a lot in terms of bracket racing ...

..... You can run whatever throttle body that you wish ... my throttle cable hook-up is on the drivers side ... Accu-Fab 1200cfm 4bbl throttle body ... yes to fan control and trans lock-up ... the Holley Dominator has a ton of programmable input and output options available ...
