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?

Suspect we are turning a corner from aftermarket EFI, or at least hope we are. For me, the dream is to avoid the nightmare that some here have experienced.

I've seen that accomplished with Motec set up by professionals for 10-20 years now at wild costs, but less often (never?) with the "lesser" systems. Given the leaps in other digital technology, I guess I am simply interested in seeing the latest take on how the cat can be skinned.

Honestly I don't think we are, I've seen more bells and whistles, complexity, a bit more flexibility on ignition and sensor choices, reliability, information (forum help), but nothing I'd truly call PEFI innovation in 10-15 years.
NA Fuel injection still doesn't beat carbs at WOT.
Where FI shines is fuel economy, maintenance (one sorted) and turbo applications, so we're talking daily driver.

To me SDS is the easiest to tune as often no dyno time is required, but all of the systems are complex to install and do right.
The reason I like SDS is it's relative simplicity for the backyard wrench. I've personally seen way too many FI projects languish or be altogether abandoned.

Why did I go with webers on my NA 914/6 conversion?
On a low mileage, low use summer play car I didn't feel PEFI was worth the huge time investment, complexity and cost for the cars application.

Plus a /6 runs real good on sorted carbs and I got a smokin' deal on my carbs and twinplug dizzy. (IMG:style_emoticons/default/biggrin.gif)
