Default Dominator ECU + DBW + NW TB

I’m thinking of switching to a DBW setup.
I presume the Holley harness 558-406 works with the Holley pedal 145-160.
As for a throttle body, I’d like to use a Nick Williams DBW unit SD-103.
Naturally, I’d presume the Holley harness “should” connect to the throttle body just fine. But, we all know - trust, but verify.

Does anyone have any insight into this?

Thanks
Pete.

I would seriously call Holley's tech line about this as this totally concerns their product.

I've got to ask, why? From your other thread it sounds like it's all up and running and making passes, and I can't think of a good reason to spend the money and switch with a Dominator.

Yeh, sometimes I just get a wild idea of possibilities.

I personally wouldn't change from cable to drive by wire with a Dominator. If you were starting out from scratch and didn't have everything already done and installed it MIGHT be a different story, but I just don't see a good benefit with that controller to make the switch.

I agree, with have switched several from DBW to DBC but zero the other way, We made 2,000hp with DBW but still had issues about once a year going into limp mode. Put new guts in TB and would be good another year. The cars we switched to DBC have had zero issues.
