Alky V6 Fuel Supply System Upgrade

[Alky V6]

Tough pump model 300 is what I need. Reverse rotation.

I talked to a tech at Kinsler today, and they don't see anything about my proposed system that would present a problem. They would prefer running everything off of the mechanical pump, but also see the advantages of separating the e and mechanical systems.

I finished most of the dialing in of the fuel table to the new map sensor this last weekend. It's within 1-3 percent now. After I'm sure I've got the table within one percent, it will be time to add the nitrous system back into the mix and complete any fine tuning to the fuel table.

The present first step in the fuel table, where the aux fueling comes in, is at 230 kPa MAP.
I've found that the e-injectors are going to 100 DC at about 273 kPa MAP even with the present aux fueling system activated. 273 kPa MAP is where the second step in the fuel map will need to be. Unless the mechanical pump is able to extend that point out a little bit more.

The time delay of the activation of the aux fuel system solenoid to actual flow is about 7 kPa of MAP rise.

After finding a hole in a tee fitting on the fuel pressure regulator manifold signal line, the fuel table up to 208 kPa is perfect. The tee fitting has been eliminated from the fuel pressure regulator signal line.
I'm presently running the car without nitrous until I get the high map region of the table figured out. After 208 kPa, where I have the aux fueling coming in with this particular 'no nos' tune, the fueling goes erratically lean. This has been a problem that I've noticed getting worse since before the last Pinks event outing. There's got to be another problem?!
I decided to completely O/H the fuel system. There had to be something that needed some maintenance.
The first thing I decided to do was check the voltage supply to the fuel pump. I was happy to find that it was about 1 to 1.5 volts low. OK. Maybe I've found the problem right off the bat and I won't have to go through the whole fuel system.
I discovered a burned terminal end on the fuel pump voltage booster relay. Relay replaced and the connector repaired, and full voltage to the fuel pump has been restored. Back to finishing dialing in the high boost region of the fuel table.
