Another start-up video

 

Sounds a heck of a lot smoother now. Less smoke too.

First start-up!

 

It cranked right up with no hesitation! First turn of the key. Throttle response is fantastic.

Yes, it is a little raw but it will of course change as the project moves ahead. The most obvious one is that the 3” cat and exhaust are not yet installed so it's wide open. Also, the tank is pretty much empty with a cavitating fuel pump causing the injectors to spit part fuel, part gas. In addition, whatever little gas is in there is close to 9 months old. Once all is said and done Ed tells me that it will have a very nice sound that is unique to tuned VR6s.

The MS-3 Pro is really cool. Before start-up Ed was able to easily confirm that it was communicating properly with all sensors; then he loaded the base map from a prior project as a starting point. Technology has come a long way....

Wiring, wideband sensor and intake manifold

Wiring:
The hairiest tasks of all are probably the wiring. Here are some progress pictures from behind the driver's seat:

Oh gosh...

Looking better already...

Here is the completed wiring to the ECU, nicely integrated:

A little bit about the Wideband 0₂ sensor: The purpose of the digital wideband 0₂ sensor is to provide a real-time feedback signal to the MS-3 Pro ECU so it can adjust and provide the perfect air/fuel ratio for any given load. Ed selected the LC-2 wideband sensor from Innovate and I can see why: A review concluded that: ”The Innovate LC-2 has proven time and time again to the be the most accurate, while maintaining amazingly fast response times to changes in air/fuel ratio.”

Passenger side:

The fuel pump relay has been reconfigured with an added relay for the intercooler fan. The coolant temp sensor is also integrated into the MS-3 Pro 3 and the A/C condenser fans are triggered by the A/C like they should:

Engine compartment:

Sensors and boost solenoid have been located behind the stainless cover (not installed in the picture) for a really clean look. No components are added on the firewall (unlike that eye sore of a Delorean starter resistor - ugh!!). Nice and clean! You can also see the little heater hose reducer to interface the car’s heater hose to the engine laying on top.

Intake manifold:

The intake fabrication is coming along nicely. Esthetically speaking, this “round tube” design is much nicer than the square d:o that Ed made for Jeremiah. At least I think so (sorry, Jeremiah J):
