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'm glad SDS has been working for you, but it's dated and overpriced compared to everything that's come out the past couple years. ECUMaster black, MS3pro, and AEM Infinity particularly. ECUMaster black has built in wideband O2, CAN, and autotune for $1099.

SDS has had built in wideband reading for severial years...you need a sensor and controller, gauge is optional.

I've never said SDS is the best, what it is the best at is for the backyard wrench with little to no EFI experience, limited programming skills, who just wants a system that works, easy to install, easy to tune, can be tuned without dyno time and doesn't need options like auto-fallatio.

I have a customer/friend who has a 930, he was running SDS which took him no time to install and tune, no dyno except for HP pulls.
This year hes been installing MS3 and meth injection, he's nine months in and 20+ hours dyno tune time, better idle, better mileage, but so far the SDS had better grunt. 435hp so far, he was over 500hp same dyno with SDS and without meth.
9 months and he's still working on finding the missing HP, more dyno time scheduled.

Obviously his problem is from doing meth (IMG:style_emoticons/default/lol-2.gif)

The 3 I mentioned are being used on 1000hp Supras.....

I disagree that SDS is the simplest anymore and at $1800 comparable isn't a good deal. ProEFI does way more at that price point.
Autotune is plug in a few parameters, drive for 5 and done. What's simpler than that?
