I got the boost controller and wideband connected and wired up yesterday and got all my brake, reverse, and flashers all working now. Still having a weird issue with the turn signals where it seems its less likely to function properly when headlights and all are on. When I have the headlights off, they function perfectly fine, but it has a very slow flash(almost like a pause and then flashes again). Running lights work just fine.
 
Unfortunately the oxygen sensor I got with my new AEM wideband purchase is bad and I have to send it back to AEM to get another one because it will only read 10.0 when connected. In the mean time I got the front left side fender marker lamp bulb replaced to fix that issue. It holds steady at 199 degrees running in the storage unit with no air flowing just the fan pulling so we should hopefully be good to go there. but still fighting small things here and there. either way I intend to cruise it over to a show about 2.5 miles away on Saturday. so we should be at our first show since the swap. still need the full tune done but part throttle cruising should be good to go.
 
Well I got to do 3-5 miles in the Dart today out on the road. But blew the ps hose on the way to pulling it back in. No real boost but just getting started on the tune. But still much better power barely into the throttle than before. Cant wait to get into positive pressure.
 
Got the new 2250 psi powersteering hose made today and a reducer that will drop the pressure coming out of the ps pump. I also ordered the connectors for the 60lb Injector's and the iat sensor and pigtail.
 
Ordered the injector adaptor orings that allow me to use the 60lb injectors in my ls7 style intake. Those will be here in a few days. I also received the 2010 Corvette ECM that will allow me to run the 3 bar speed density tune for boost. So after the injector orings come in ill be putting them and the new 60lb injectors in along with the corvetter ECM and we will get back to the tune.

I also got my power steering fitting in the mail and installed it and the powersteering fitting in.

I also got my intake piping back from Bay city classics where he welded the 3/8 npt bung in for the Intake air temp sensor, that way the computer doesn't think its negative 40 outside.

I got the relay wired in for the ignition switch as well. Mine is one of the switches that has that drop off in voltage between the brown and blue wire going from run to crank and then back to run. Its very quick drop but its significant enough to kill power to the ecm and not allow it fire up the car properly. So having the relay in there allows me to not have to use a push button and has enough residual 12v power to allow me to start and shut the car off properly. I just tied the blue/brown 12v run and crank power wires from the bulkhead connector at the firewall together and used them to trigger the relay allowing the 12v battery hot to fire the car.

Fingers crossed ill have some driving videos/car show pictures/videos this weekend. Depends on how crazy hot it is here.

I'm old school, don't know much about all this new technology, I do have an MSD Atomic fuel injection to put on my 340. What you are doing amazes me, get that thing on the street and DESTROY some perfectly good tires.

Thank you very much. I'm quite the 180 from that. I rebuilt small block carbs and motors growing up, but never owned a carb motor until the slant 6. Learned some things here Nd ther but since I was 16 I've owned fuel injection because that's what I knew best. This just gave me a new platform and direction to grow and develop skills in areas I've never pushed myself before.
 
I doubt I'll ever see your car in person as you're about 3000 miles away.....take lots of videos!

Here is the injector adapters that allow me to use the ls1 style connector on my ls7 style harness.

And the fuse/relay box now that I have the ecm, fuel pump, fan and ignition relays wired up and the fuses for each along with an extra for accessories inside the car.

And the finished product.

Bummer! Oh well, soon enough.
 
Got the o-rings installed on the bottom of the injectors today and got the rails tightened back down. Swapped out the ECU's, and the 1 bar van map sensor for the zr1 3 bar map sensor so we have everything ready to go when we start the speed density tune. the 96+ degree temps made me not want to star the tuning process today, so we will wait for a day that its a little cooler out. Ill just have to set the boost controller up to start out at something a little safer for the start like 4-5 psi and then go from there since we can adjust it on the fly.
 
Got to go on the first drive today since we flashed the speed density tune. No crazy raging on it or smokey burnouts yet. Just cruising and slight throttle increases to make sure everything is happy now that we've switched it all and verifying all the air fuel ratios are good. After some research i've discovered I need to wire in a 1k ohm resistor in order for the aftermarket tach to function properly with the factory LS tach output. so I should be doing that tomorrow.


I set the electronic boost controller up to basically open the wastegates anytime I got into the throttle bleeding off the excess gasses so it kept me out of boost(failsafe move to save me from myself)
 
Very nice job. I can’t believe you did all that in 4 years. It took me nine and there’s still stuff left to do. Glad you stuck with your plan.
