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?

I've been eyeballing one of these for Dads old Chevy: Go EFI 4 600HP System with timing control.

I wouldn't do a center mount FI on a 914, runners are too wide, plus it's backwards engineering. Essentially it's TBI from the 80s.

For the 914n6 I've got my eye on ECUMASTER EMU BLACK STANDALONE ECU. Overkill but pre-programmed for the VQ35 swap. A little cheaper without the Autotune.
I've read the DIYEFI/MS3 tech is not up to today's standards.

The ECUMaster stuff looks quite good. I'm dying to try it out. (IMG:style_emoticons/default/laugh.gif) Their sales and engineering organizations are pretty engaged with consumers (especially the guys at ECUMaster USA) too which is really nice.

When I think about EFI, I like the idea of the "who" behind the system.

Any company can go out, but I put more stock in Holley or something like Andrew pointed out (the MS3 unit). I think about some of the old Haltech or other random systems, and trying to keep a 368 or 486 laptop going to support them.

Who is good, but AFAIK the Holley system is quite under-performing compared to almost everything else available. They're famed as a carb company, not an ECU manufacturer. IMHO you're better off going with component from someone who specialized in the engine controls/data acquisition market.

Companies like Haltech are still around and make good products-it's a somewhat unrealistic expectation that a company will allow backwards ECU compatibility with all of their software package changes. You face the same issues in the industrial world with needing old computers to talk to ancient electronics, even those with companies still in existence making high end products.

One of the main reasons why I like MS so much. They do a LOT to make sure they have backwards and forwards compatability. Its just the hardware itself that they change to make the packaging better and have a more "All in one" unit. Thats really the only difference in their systems.

Microsquirt is a hair different, but its designed to be a simple fully enclosed unit for cheaper than anything else.
