Today I spoke with Ty Peek from peekperformanceparts.com. We connected over a post I made about Holley Dominator EFI and the IHI/6.2. Basically I asked how the SBV is controlled. Most people said use Haltech switch to Motech, yada yada. He actually took time to direct message me and assuage any fears I had.



Since I don't have any actual hardware the EFI V6 was not showing any DBW setup so I couldn't answer it myself. Here are the parts I choose from the Holley configuration and have in my cart.

  1. https://www.holley.com/products/fue...ion/dominator_efi/dominator_ecu/parts/554-114
    1. Kinda important... also is required https://www.holley.com/products/fue...minator_efi/dominator_harnesses/parts/558-308
  2. https://www.holley.com/products/fuel_systems/fuel_injection/hp_efi/hp_harnesses/parts/558-116
    1. Main harness. Provides 4 inputs/outputs that are programmable. Connects to J1A/J1B.
  3. https://www.holley.com/products/fuel_systems/fuel_injection/hp_efi/hp_harnesses/parts/558-210
    1. Injector harness, connects to Main harness. Most common Hellcat injectors are EV6.
  4. https://www.holley.com/products/fuel_systems/fuel_injection/hp_efi/hp_harnesses/parts/558-311
    1. Ignition coil harness. Will connect to the ignition capacitors on the back of the heads as well as the main harness.
    2. https://www.holley.com/products/fuel_systems/fuel_injection/modules_and_sensors/parts/554-122 required drivers for ignition, connect to main harness to power coils
  5. https://www.holley.com/products/fuel_systems/fuel_injection/harnesses/parts/558-450
    1. Dual drive by wire, will control Kong throttle body as well as the SBV
  6. J2A Input, J2A Output
    1. Not happy that I have to get this but if you get the Dual DBW harness they use J3/J4 so I have to get these two and I get 23 inputs/outputs.
    2. https://www.holley.com/products/fuel_systems/fuel_injection/harnesses/parts/558-401
    3. https://www.holley.com/products/fuel_systems/fuel_injection/harnesses/parts/558-402
  7. https://www.holley.com/products/fue..._sensors/sensors/oxygen_sensors/parts/554-101
    1. O2 sensor for Bank 1, not running duals to start with, the J2A/J2B harness is already terminated for two when I care to get one.
    2. Not happy holley locks you out of o2 sensor with their proprietary ones.
  8. https://www.holley.com/products/electrical/wiring_and_relays/parts/7564-HC
    1. Two MSD Solid State relay kits, was quite impressed how you can wire these to the Dominator to control fans, fuel pumps, trans brake and other power hungry sources. Kind of like they were meant to play together.
It's ordered and on its way.
So awesome and such great information man. Really putting in the leg work. Sorry I don’t have any information to benefit you here

I also started my Holley courses tonight. Of course if there is anything I can give back from what I learn I gladly will.

When I was poor, it was chicken pot pies. 28 cents a piece in 1972. For $0.56, I was full (of starch, mostly).

Pro tip, get some of those package white chicken breast and put them in the bottom of the bowl before adding the Ramen and hot water. I lived on that in college and it's handy when you go camping as well.

I used to go to Arners Restaurant that had a huge salad bar. Order the dinner special. Pig out on the salad bar and take the dinner home.

Heat it up for next night's dinner. Cheaper than buying and cooking it.

So some technical things. The hellcat map sensor is really a TMAP sensor. It does temperature and pressure.

The Gen 3 harness is made for 5.7/6.4 units and includes a 3 pin map sensor and 2 pin MAT sensor. There are two ways of doing this.

option 1
De-pin the Holley map sensor harness pigtail and use a mopar connector using the following reference guide:
IMG_1599.png
Pins 1/3/4 would be re-used.

In regards to MAT, the Holley harness is a ground and an input. Theoretically this could map to pins 1/2. The blower port lid sensor would be used for temperature. The back of the blower port for manifold pressure. Custom sensor data would be needed.

option 2
Buy an AAD reference port block use the outside sensor for temperature. Drill/tap the reference port to 1/8 27-npt and use holley 3.5 bar map sensor. Select it in the drop down and be done.

I’m leaning towards option 2. I like plug n’ play. I have one on my car but cant remember the reference port thread pitch/size, might email AAD to see if they can do me a one off.

Option 3
De-pin both. Put MAT sensor pin and map pin on one tmap sensor.

In any instance block off ports will be needed. Easy day on those
