I just found that holley has the hp efi available for the newgen hemis. Plug n play for about 1500 bucks. Its a great system with some data logging but clearly not as expensive as the dominator but its about 800 bucks cheaper. No boost controller but boost friendly. Will run the coils as well as far as I know.

After so much debate and parts buying and selling. I will likely go this route for the money. If need be ill add a data logger later anyways if I need more data for strip tuning. Currently it will log the major important stuff for a turbo car I will need.

Just wanted you guys to realize the hp efis potential as an option for you not so needing the top dog efi and want a bit more customer base besides diy on your own alone.
 
Does this only control the fuel side?

Holley HP is a pretty much customisable, fully featured EFI controller. It can be used TBI, batch or sequential and in batch and TBI with or without ignition control.

If you are interested, I suggest you waltz over to Holley and do some reading.

"Self learning."

The HP ECU is used on several of their systems. The simplest does not require a laptop or the more expensive touchscreen display, just a tiny handheld control.

These things are VERY versatile.

You can buy them "all kinds of ways."

Maybe I should've been more clear...will it still require the MSD Hemi 6 to cover ignition control or will it do it all? Wiring harness included? Been noticing a few of these things looked like great deals until I added all the other things I was gonna need to make it work...
 
I thought I did. The HP EFI is a stand alone, complete, VERY capable, and VERY customizable system. It will control fuel and timing, along with a few other things. I REALLY suggest you waltz over to Holley and do some poking around. This is a VERY detailed system, with inputs and outputs that are configurable to do various things, like shut down the AC under throttle and so on. It is a VERY full featured system.

I really suggest you go over to the Holley forum, register, and ask some questions Danny Cabrel is very well known and either does or did work for Holley, seems to be a very nice guy and knows these systems inside and out.

I'm seeing the HP EFI at a grand, four and a quarter for the main, 2 add-on harnesses for a hundred each, and I can't find the harness for the drive by wire listed...so a minimum of $1625...

Most efi is not gonna be with a drive by wire throttle setup. Cable is to easy and very few would ever want one in a stand alone application. The pedal alone is as much as a throttle body. Why in the hell would any body want a slow responding pedal system anyways??? Makes no sense to me.
 
I agree...I was just quoting based on what the Holley site said was included and not included...
 
But that IS the beauty of the Holley system. Whether harnesses / connectors are available or not, you can build what you want. You can easily change the TB, I see no reason for using what amounts to using a fancy motor controlled valve.
 
So, if I can run a cable operated throttle body, then I just need to hope that they get the VVT sorted out before I'm ready to go. Will it store fault codes like an OE system, or am I asking too much?
 
Not exactly fault codes but it does have a logging feature. This thing is not a toy. It's got a LOT of features.

Some guy over on the Bullet was pointing out a rather interesting situation where this thing saved his a$$. I forget I think this was about a 9 sec? turboed? car? running either an HP or Dominator

EDIT found it you need to read this. Fuel pump took a dump and the Holley stepped right up and added fuel to the thing right THERE

That is why the holley is such a beautiful piece everyone seems to be going to. It is an unbelievable control system.
 
Wow...this is painful...I've avoided Holley carbs like the plague, but it's sure starting to look like I'll be running their injection...

This Holley setup has the potential to be a great system. My only issue with the harness that you have linked to is that it APPEARS to be a harness designed to be used in CONJUNCTION with a stock computer and harness. (I could be wrong)

It is clear from Holley's website that they do offer a kit for the GM LS motors for around $1600.00 which is an excellent deal. If they can do the same for the Hemi that would also be an excellent deal. You would simply need to add a cable operated throttle body and upgrade the fuel system.

At $1600.00 this is about 1/2 the amount charged by FAST.

No, that's for either the HP or Dominator ECU. There's probably an integrated kit, I just came across that.

I had the old Commander 950 running, as simple as I could get, with no spark control and TBI. I bought a Holley HP EC and harness kit which was designed to update the Commander to the HP ECU. It also came with a new MAP sensor and a couple of other things, I believe a new temp sensor. At the time it was 1300 bucks

Now, the SAME ECU is also used with the Avenger and Terminator. There is no laptop, you use the handheld controller. But you CAN just hook a laptop to it, download and add the Holley HP software, and -----you have an HP system. Gives you more features and control

But you CAN get it running with the handheld device.

Some guys are using a Windows 8 tablet with these

As near as I can find out, these are WAY more versitile than the FAST or some of the other systems. If you are willing to "solder and splice" you don't REALLY need some of the special Holley harness adaptors. The documentation gives you ALL the pinouts and wiring
 
From what I saw, $1625 gets you the HP ECU, Hemi main harness, injector harness, and coil harness. Seeing as the drive by wire isn't necessary, it looks to me like that's got it covered.

Now if they're working on the VVT, can I add it after the fact?
 
The closed loop adjustments at WOT saving motors looks awesome. I need to see if MS3x has the same capability
