ABS: The ABS is not operational due to not seeing the 128K pulse/mile VSS signal or data communication from the PCM. But I wanted to test whether the automated bleed can still be performed as the module is still plumbed in. I can confirm that the automated bleed via the ODB connector still works IF you supply 12V on the VSS signal line to the module so that it does not see an open circuit and set a DTC. All DTCs had to be cleared before I could proceed with the bleed. On my truck this circuit is accessible at inline harness connector C152 which is located under the underhood fuse block. Yellow/black wire.

 

So what were the final numbers? Hard to read those printouts

 

884 rwhp/863 rwtq @ 17 psi and 20* advance(1120/1090 crank)

Fist pull was with only 9* advance and did about 300RWHP less.

 

It does idle smooth, that is surprising.

 

One thing the Dominator doesn't have is misfire detection. Had an issue that was causing target AFR on the right bank and 6.X on the left when in boost only. Actual was likely 6.X on both.

 

I swear I saw those nostrils on the hood open wider when he nailed it.

 

Finally getting around to mounting the Merc Marine/Holley/IGN-1A coils along with the big wire kit for them. Also found 1 more wire with a singed spot on the insulation. Funny how it runs good until the cylinder pressures get high and the path of least resistance for the spark is no longer the plug gap.



Hopefully, this cures the misfires. Also read that the Dominator and GM coils don't get along.



Similar mounting to how I had the GM coils. Drivers side I just spun a couple of nuts onto the longer motor mount bolts that I had used. Pass side I bolted to the frame under the motor mount. Drivers side is shown flipped down and flipped up. Had to change terminals/boots for the Holley coils.
