Gang, it has been several weeks since I updated you on the mechanical aspects of my project…So here's an update of my progress… I have resolved the fuel pump wiring. Instead of running two separate fuel pump outputs and leads from the SM4, I decided that I would only use the main default output to run both pumps simultaneously. The default fuel pump output on the SM4 is now connected to both pumps and I split the trigger wire to both relays (one to each pump), and it is working perfectly. Both pumps stay off until I turn on the key, then the ECU primes both pumps and shuts them off until I start the motor. I think the secondary output that was reprogrammed lost its programming, perhaps after the ECU was re-flashed. Anyway, I will always run both pumps instead off staging them. Probably safer anyway. Now I have only to complete the installation of the water/meth injection, and connect the boost gauge. Btw, the base map is running well, and should be good for non-boosted driving. It is still a bit rich, but I will lean it out am little this weekend. I adjusted the idle set screw because the idle was very low (450 rpm), once I did that, it stopped idle hunting. I'm planning to drive the car this weekend. Final tune should be within a few more weeks. If the drive goes well this weekend, I will drive it over to Tampa for the final wet sand, buff, and repaint of the front fender.

BTW, most of the interior is back in the car...Carpet, upper dash, passenger side airbag, headliner, visors, dome lights, rear deck, rear seat. Some of the speaker wire I ran (non-Monster) corroded badly, and I had to run new Monster to replace it. I plan to install the center console, stereo, AC control module, AC vents, lower dash, dash pocket and front seats this weekend.

I tested the sound of the Walbros bleeding into the cabin with the doors shut, and they are almost imperceptible. When the engine was idling, I could not hear them at all. I was sitting on the back seat too, so, no issue with the pumps.

Just about there...

The AquaMist Water/Meth System is installed, tested, and working. A huge thanks to Dan Osypian!! Great job, my friend.

We had a few snags with the wiring, but all is well, and I am finished with wiring, except for the Autronic Reluctor that converts the analog speed sensor signal to a Hall signal so that the Autronic Traction Control can function. 

The reluctor is on its way to me, and I am almost ready for the tuner. 

I did not drive the car last weekend, but I do plan to drive it this weekend. I will keep you all posted!!

I saw the headlights today...Wow! They look good. They are painted, wet sanded, buffed and cleared. The LED strips are attached, and the lights are being cleaned up, and then assembled within the next few days. They look absolutely BADA$$, IMO. 

Leaving work now to go and work on the car. Gotta drive it this weekend....
