Holley Dominator on a Ford Mod Motor

[rossmacd]

I've got a 4.6 DOHC in my fastback, and am strongly considering using the dominator system for my efi (I've got factory Ford stuff in there now, but it's got problems) I understand that there are some compatability issues with Ford components, but can't seem to her a straight answer as to whether there is a work around or solution... Does anyone know? Our even know of whom I could ask? I know pt.com is mostly Chevy oriented but I'd appreciate any help.

You'll need to make some changes to run the Dominator EFI.

Factory crank sensor isn't supported currently. You can run a 4-0 or 60-2 crank trigger up front and there is an aftermarket 58x to replace the stock internal but, that requires engine removal and disassembly. I haven't look closely enough at the cam to see it's current trigger scheme but I'm betting it can be modded to output a single pulse rising or falling edge in the right window.

Next, the factory coils aren't supported either. You'll need to swap out to LSx coils or you can run Holley's DIS (wastespark) coils. If you run the Holley coils, you can run bank to bank and eliminate the need for cam sync...if simplicity is what your after.

Aside from needing to build the main harness to fit the other connectors....all else is supported and will work. There are two guys I know have them up and running, haven't had a chance to see which of the above mods they chose to work from.

Thanks for the reply. What would I need to do to convert to a 4-0 or 60-2 crank sensor? I wouldn't mind switching to different coils; I understand that the Ford coils are pretty weak. I'm not looking at making that much power, but reliability is always at the forefront of my mind. I'd be sad to give up the clean look of the factory ignition system, but you gotta do what you gotta do.

Would I see any difference at all in going bank to bank on the ignition, as opposed to sequential? Would I have to go bank to bank on the injection as well?

The 4-0 is available from Reichard Racing http://www.reichardracing.com/crank_trigger.php# and would require a cam sync to run LSx or Holley's DIS coils It's a flying magnet configuration (outputs a analog sine wave) wihich works well in most instances however, can be subject to noise if twisted or shielded cabling is not used.. I'm not aware of any bolt-on 60-2 wheel for a Mod, you'll need to have the trigger wheel drilled for the front mount and possibly modify the Reichard Racing bracket to work with the 60-2 sensor if you want to run Hall Effect. The Hall Effect is a 3 wire sensor which outputs a 12V digital square wave which is abit more robust vs noise and offers a tad more resolution. Either would work well in your application if installed properly. As I mentioned earlier, you can run Holley DIS with 60-2/No Cam Sync but, it must be in bank to bank fuel strategy. If you add the cam sync then you would run sequential fuel/wastefire DIS.

Here's the Accufab internal wheel http://www.accufabracing.com/modular.htm as an option aswell.

Economy and cylinder to cylinder fuel distribution will "slightly" improve by running sequential. We've installed quite a few Dominator ECU's with dual WBO2's and almost all have a slight variation bank to bank even in sequential operation. In either configuration, WOT will have pretty balanced A/F. FWIW....I just finished up a Procharged 355 that we tuned in bank to bank then switched to sequential...there was ~3 to 5% change in the idle and part throttle fueling.

I see, I misunderstood your original post. As long as driveability won't be effected, I don't think I'd really mind bank to bank; 3-5% isn't a big deal... I don't think. This car was my dd, but I hardly get to drive it now; I'm mostly driving around in my work truck or my wife's car.

What about DBW?

Another thought is to use the MSD 6LS Igntion Controller. It'll run the from the factory sensors, drive the LSx coils and output the tach output to the EFI for fuel control. IT may be a reasonable cost vs trigger wheels etc.

Yes, GM, Ford and Nissan DBW applications are supported.

I think I'd prefer to use the crank sensor. I'd like the dominator to be able to do all of my tuning, without having to turn the msd as well.

I'd like to buy everything from one place if possible. Do you think you could work up a quote for me?
