My Holley HP EFI installation thread

So, what the hell is White95 doing NOW? :evil: Those who have followed my build thread know that my car sometimes sits for months, if not years at a time. A lot of the times is because of life getting in the way but at times its waiting for a tune. In fact, I've never had the car tuned since I had the Pro Comps ported and installed the TFS-R intake. That has been nerely two years. Now that I'm upgrading the complete HCI, I've decided to rip out the factory engine management system in favor of a Holley HP EFI system, PART# 550-604, but why? The Holley setup is much newer technology, nearly plug-n-play, user friendly with modest tuning knowledge, 'self-learns' itself for the start-up and drive ability tune. The software does allow for fine tuning on the dyno. It interfaces with their own 7" LCD display that i'll couple with a custom gauge cluster from Steinmann Performance. Well, eventually. This thread will be fluid and any questions will be answered. (Look mcglsr2 , colorful hyperlinks!)





The tear down

 

The engine and injector harness

This is a diagram of the main engine harness for those who like reading diagrams:



This is an overview picture of the main engine harness for those who like pictures:



The kit that have came with an over the manifold, universal Bosch style injector harness. However, after reading this thread, I realized this harness needed some work to properly work with the SEFI Ford setup.



Wiring the engine bay

The modified injector harness simply snaps on!





The stock style distributor and remote TFI module [lower left, in front of the strut tower] will be removed and replaced with this "fox style", TFI mounted distributor. This particular part came from a local guy, Stuart, who has a NASTY solid roller, 410w/AFR220/Super Victor 600 rwhp SN95 that's controlled by the same Holley HP setup I'm installing. In fact, he has been a wealth of information and we'll see pics of his GT later.


We will be referencing this drawing:

What don't you get bro?

 

B.mad - This will replace the ECU and engine control harnesses completely. The Holley system literally self-learns the tune but also allows fine tuning. This was a major selling point since my car has sat for months upon months waiting for a tune at times.

With additional parts, I will be able to ditch the distributor/TFI altogether and run a legit DIS (distributorless ignition system) to be completely awesome.

 

Not even close!! I did jump into the deep end with some initial tear down and minor assembly work!

 

I don't care This process will me several days and will not be rushed.
