Holley Dominator EFI

Thanks Guys. Yes, I do have a little time these days but it is a challenge with a 2 year old. I just have had to get creative with my time and where I work.

Finished the harnesses in the kitchen for example.






These are the ecu connections that will pass on the engine bay with bulkhead plugs.

Keith, I really wish I had your time/motivation for my own stuff. Looking great

I think we all have a little time. Its the modivation part that gets me and lack of skill.

I think Keith has a lot more time than most of us do at the moment. He does have a great deal of attention to detail and skill, though.

Harness for the ecu is built. I am sectioning it for firewall plugs tomorrow then installing it.

[KBScobravert]

Little bit of coil/bracket action. I need to shorten the coil sub harness.


The plan is to mount them near the K-member on each side.

Hard to see in here now that it is all loomed up but
Fan triggers Hi/Lo
Indicator light leads for the fan speeds Hi/Lo (lights are in the cluster and can be turned off with a switch)
Oil cooler fan trigger
Indicator light for oil cooler fan also same set up
Oil temp sending unit pre/post cooler
Oil temp sending unit for gauge
Oil PSI for ECU
Oil PSI for gauge
Ambient temp sensor
Pre-cooler temp sensor
Post-cooler temp sensor
Radiator sensors (one at the inlet, one at the outlet)
Evac pump relay trigger





Tomorrow and Monday I am going to finish the EFI harnesses. Hopefully start up in a few weeks if I can keep up this pace.

I want the sister parts hookup. Im jelly of the new setup man.

I just got my email back from AEM with the prognosis on my old ecu and injector driver. Both are smoked beyond repair. It is nice to know at least that when I thought the battery charger over charged the battery it is what smoked these two also.

Why the switch from AEM?

AEM support sucked. Doesn't control near the functions the Holley will. AEM is not very user intuitive and has limited data logging. There were connectivity issues with ecu to cpu. AEM's cam/crank or EPM is a band aid solution but now the motor is configured to run coil-near-plug so without complete revamp I am committed to that configuration.


Support on Holley's forum and other sources has documented an endless number of configurations with easy to follow steps. Holley uses a cam and a crank sensor that is infinitely user friendly with any crank or cam sensor on the market. For me, I am using a 3-wire Explorer cam sensor and a Cherry crank sensor http://www.digikey.com/product-searc...herry+gs100102 .

The AEM ECU and injector driver are going to AEM for a clean bill of health and then the entire system from ECU, driver, coils, EPM, harness, boost control, gauges, extra Ford 60pin ecu connector and pins, etc are all getting sold.

I am not real set on the 556-112 coils but to have a system that was designed, built and sold to work together. But my sister already has them coming so no punking out now.

Just ordered up Holley's 83pound injectors http://www.holley.com/522-838.asp to step down from the Trickflow 120s.
Even on the E85 and at 650rwhp and 14pounds of boost, I was only in the 62% duty cycle
Going from E85 to 93oct. And may try a E85 tune on the 83s just to see.
Nice thing about using their injector, the data is all in the ECU already so no guessing what is what again.

Also ordered their CNP coil built like the LQ9 heat sink truck coils I already have but built for their EFI. http://www.holley.com/556-112.asp

This is turning into a complete Holley EFI system down to all their sensors, wiring etc. It better start and run right off the bat.

I bought some extra connectors for three wire transducers and I found the schematics for a Ford 2 wire IAC on Holley's site.

I have a 5bar (holley) for MAP and a 3.5bar(AEM) for dome pressure.

For IAC I want to use the Ford 2 wire. Danny C says it is better than the gm the harness is pre built for. Faster and more accurate.

You will have to put a new connector on the harness for the 5 bar map... And my harness was pre-pinned for a Chrysler IAC. I used a GM IAC on mine because my throttle body is off a LS car.

Repinning the IAC is easy... Pull the grey wire holder off the back of the black plug, then pop the purple cover off the other end. This will expose the holding clips. Get a small pick or screw driver and just barely pop them up while pulling the wire from the other end. The wire will come out very smoothly with the connector still attached. Move the wire over to the correct spot depending on what IAC you use.
