Holley EFI, Not just for American 4BBL carb replacements anymore... Options

[horizontally-opposed]

So I am hearing this is a very attractive setup for 4+ cylinder engines, and can be made to work with ITB setups for a flat six, such as PMO's. The 4BBL pricing sure is right, and it's said to be "self tuning" and a dream to work with/on.

Anyone have any experience of this, or know of a Porsche engine running it?

Chris Baker (tygaboy) is going to use the Holley HP EFI package on his LS3 running individual throttle bodies so I'd see no reason same system couldn't be used on a flat /4 or flat /6.

They claim:

NEW V4 SOFTWARE FEATURES
“Quick Start” ignition and fueling strategy for LS x Engines
Data Logger. Scalable axes, Smoothing, Multiple graph view ability, Pre-defined notes fields and many more
Strip Chart Real-Time Data Viewer
Integrated Boost Control - Boost vs Time, Boost vs Gear (Time or RPM), Boost vs RPM, Boost vs Speed, Launch control. Boost launch builder, Over-boost safeties, Boost scramble
Traction Control - Power reduction via timing, nitrous percentage or boost (Requires Davis Technologies Holley Module)
“Quick Start” fueling for all engines
Option for VE based fueling strategy
Fuel Map and Learn Function Smoothing

The ECU alone is $1100 which isn't too bad. Personally if I was to do the aftermarket EFI again I'd go Haltech (no more DOS based programs (IMG:style_emoticons/default/smile.gif) ) (the more I read about the Holley HP/Avenger and Dominator ecus the more I like them).

I know Hot Rod and the other V8 biased magazines really like the Holley EFI stuff. I know for the many older hot rod guys the main appeal to this new generation of EFI is plug and play. Not everyone wants to spend the time and money for dynos to get the EFI to play nice with the motor.

"Self tuning" is like the holy grail for some people. I think there would be more aftermarket EFI installs on 914s if someone knew for a fact that in one weekend they could remove their carbs or D-jet/L-jet and install MS or Haltech or the Holley and know that once they turn the key their motor will run as good or better than before without having to turn on the laptop and figure out which button to press or 3D map to play with.


The Dominator ECU can support dual drive by wire TB's, that would be neat with a /4 or /6 , no linkage would really clean up the install and avoid some issues people have with them.

I worry about “Hot Rod and other V8 biased” magazines actually carrying bias into the editorial side of the house. Do they really like it? Or, do they really like the resulting ad dollars when the editorially ‘like’ it.

I often suspect the latter, especially for EFI systems. Mainstream magazines don't generally seem to cover the really cool stuff in terms of vehicle controls/electronics.

The HP EFI is rather low on I/O, even for the price. The Dominator has a bunch of I/O, but at $2000 is getting into the range of higher end stuff with likely better control strategies.
