So switching from a Holley Hp to a Dominator for the 4l60e control. Holley Hp fit nice under passenger kick panel. Not so with the dominator. I have all the wiring through the passenger side like stock through the square hole on passenger side foot well. Just no place for this but on the floor. Wiring isnt long enough and I'm not drilling through the fire wall to get length. Anyone have one mounted in a Thirdgen? Would be nice to see what was done. Thanks

Why not extend the wiring? You could bolt it to the dash side of the kick panel cover on the passenger side, I did that for a few years once. Wasn't even noticeable. You could make a plate that bolts onto the square opening of the frame that the harness passes through and mount a big connector to that plate, that would keep you from having a bunch of solder joints in the middle of a harness run. You could drill a hole in the top or top side of the transmission tunnel and run the wire through there; I have mine that way.

Not drilling any extra holes. Do you have a pic of where yours is mounted?

Hawks told me recently that they mount the Dominator under the dash in stock-ish location. Hard to believe, but that's what they say.

That Ibwould have to see. My HP fit nice. The Dominater is twice as big. There is no way its fitting there unless the air unit is removed.

I imagine it would have to be oriented long ways vertical. I could see it maybe fitting if you use all the space from hush panel to upper dash.

I guess you could but it sticks out the bottome of the dash. It's too long. Tried this numerous times. Was getting frustrated finding a place to mount clean like the HP will try again tomorrow. With added wire for the trans and second 02 there's more wires now than stock. Lol

I have it mounted in the stock area, kinda. I made a bracket that bolts into the spot where the 4x6 speaker mounted and the MegaSquirt bolts to the bracket.

I have a Holley dominator ecu. I had a Holley Hp that's bigger than your mega squirt and it fit ok. The Dominator ecu is twice as big as the Holley hp and prob 3 times the size of your megasquirt. Its big.

Sell it and switch to an MS3 Pro evo or ultimate. Both have transmission control, knock control, come with a base tune, have lots of spare outputs and are smaller then my MS3 extra. They can also be used for traction control, launch control and flat foot shifting which is why I'll be switching to it in the near future.

EFI Connection is making a bracket to mount in stock location for our cars.

Are you serious? This isnt even on the table. I'm just looking for opinions on the mounting. Not selling anything. I just bought it.

IROCZ1989

iTrader: (1)

Well this is news. Can you verify this? Where was this heard.

I don't know why the holley stuff is the size of a briefcase. The pcboard of the ms3 ultimate is small.

The HP fit fine. The dominator is like 2 HPs side by side. Idk. The only reason I upgraded was to get the trans control. The 80 or so inputs and outputs I'm only using a few. 2 02s are a plus. There has to be some kind of difference between the 2 I assume.

anesthes

iTrader: (12)

No idea. I've not compared them side by side. For all I know it could be two distinctively difference units and a CAN interface between them in a single case.

Trans control is good stuff. If I blow up the TH350 in my drag car one day I'll do a E trans and make the ECU shift.

Not really. You can only pick left, right, average, leanest or richest as to what the ECU will show. You can't assign different injectors to each O2 or bank like other systems. Waste of a feature in my opinion. Sorry.

Give Holley a call and tell them. I needed it for the 4l60E anyway.

anesthes

iTrader: (12)

I'm trying to decide if that would be useful functionality for fuel trim..

It would be nice to know if one bank or the other was richer or leaner, but I feel like the resolution would be a static cylinder trim to compensate for intakes that have uneven distribution.

-- Joe

It is useful. On the AEM Infinity you can tell it what injector you want controlled by what O2. On their 508 we added a second so the onboard controlled one side and the additional one controlled the other. With no other changes it immediately made a 3-5hp improvement everywhere on a 540hp build. I know that’s not much but thought it was interesting nonetheless.
OP yes I know you needed it for trans control, and I have mentioned it to them. But you’d think it’s there, why not be able to make the best of it.
Just my opinion.

I've been down this road a million times. It's done and over. I'm at the point of mounting the unit. This is what the thread is about. If you want to talk fuel trims or 02s,or why Holley did this or that. Just start a new discussion. I personally am at another point here and dont want to derail the thread. No disrespect intended.

I have contemplated going through under the air box. Any grommet setup or bulkhead that can accommodate alot of wiring?

So where did you mount it?

QwkTrip

iTrader: (22)

I see the bracket for 4th gen in the engine bay. About $300.
There is another one for 3rd gen?

At $300 I just want to see their pictures so I can make my own.

I'm still stumped how to mount mine in a stock-ish location... I may just bolt it vertically in the kick panel area.

QwkTrip

iTrader: (22)

Holley should sell a $5 plastic model so people can work out mounting ahead of time. Or a 3D model that can be printed.

Improved Racing sent me a free plexiglass crank scraper so I could experiment which one would work for me.

89 ******:
I mounted mine under the dash where the old HVAC box was ( I removed that) You can check my build thread for pics in the LS forum.
Ran the Holley wiring harnesses through the big connector hole behind the kick panel.

If I had to do it over again, I'd try to mount it more towards the center of the car, still under the dash. There's so many wires/connections they start to interfere with the plastic cover underneath. It would help spread them out more, instead of stuffing everything in a little area. Just my 2 cents.
