David,
So, what had happened was...


Bucket 1 - Got too aggressive with the step-up drill bit - cracked the danged thing.


Bucket 2 - Drilled holes through top for the wiring for the second pump, wasn't thinking about the Teflon wiring not sticking to any glue or sealant (whoops!). Didn't like the fact that it wouldn't be able to be sealed properly.


Bucket 3 - I just flat out dropped it and broke the edge off.


So, there. That's why a guy would have three trashed fuel pump buckets!


As for Home Depot - I was pushing my buggy back to the store and just happened to run acrossed a couple more left out on my way there...

 

He also forgot to mention how he somehow managed to add a cylinder, two valves and a spark plug to his 16V engine...

 

:b ang:


I'm still so pissed that I can't even multiply 8x2 to get 16.


:b ang:

 

So, quick update. Loren and I spent a little time on the car this weekend and, acting on a tip from David, we decided to go ahead and check out the last remaining piece of wiring that I had to buy from someone else - the coil harness. As par for the course, it was jacked up too! The #1 and #7 control wires were reversed. We now have a perfect score. Every single piece of aftermarket wiring I had to purchase has been jacked up! How danged hard is it to look at a pin out and follow the picture?


Good news is that the car fired right up and ran smoothly until it backfired. Bad news is the backfire. Of course this is pretty much definitely from a massively rich AFR from the tune. Anyone have RELIABLE data for LS9 injectors converted over for the 0411 computer? I've already got a set of LS3 injectors on the way because I found a file eaglegoat posted with the correct data for them in the proper format (thanks eaglegoat!). I'd still like to find a proper proven) file for the LS9 injectors to compare them to what we have.

 

I'm going to start with the small stuff first today


I cut down the automatic shifter as low as I could go and installed the conversion kit to install a manual shifter ****. In the pics you can also see that I removed the cigarette lighters and replaced them with twin 2.1 amp charging ports. I also installed a switch to turn these on or off where the ash tray used to be. I wanted the option to use them whenever I wanted, without permanently wiring then constant on and keep the LED's burning all the time.








The emergency brake handle will eventually be replaced by a billet unit that I bought. It will be powder coated black with blue accents.

I also finished up the wiring for the line lock and secondary fuel pump, including mounting the switches in the center console.





Loren helped out and finished reupholstering my front seats for me while I was doing the above items.





I also fabricated (and powdercoated) a bracket for my rear-view camera and installed it.











I've still got several odds and ends to button up, but, I can finally see the light at the end of the tunnel on this project!

 

Well, I guess I should have posted the big update...


After replacing the injectors with LS3 units that we have reliable data on, the car fired right up! We still have a lot of fine tuning to do, but it sounds wicked. It does look like trying to fire it up with the super-rich data for the LS9s fried the wideband sensor, so, we'll be replacing that this weekend before working on tweaking it. Loren and I are definitely not hptuner experts, but, even we thought it was odd that the minimum pulse width data on the LS9s were 3 times larger than the LS3 injectors. Whatever it was, it fired up and we do not have backfiring. We'll tweak it a bit to move it around a bit, but, we'll be waiting for David to get back from driving his little boat around the world to let him fine tune everything for us!


So, here is the video...

Sounds WICKED!!

 

Sounds good !!

 

That's a good looking engine bay. Where will you mount the reverse cam screen? Is there still a shifter "button?"

 

Thanks guys! The video doesn't even do it justice, it sounds so much better in person!! The neighbors might get a little upset when I drive it to work every now and then though (I leave for work at 0530).

 

Thanks bud!


I'll be replacing the current radio head unit with a double DIN android based unit. I'll be picking that up after the wife gets over the sticker shock from the rest of the build...
There is no shifter button any more. You press down on the **** and it releases the shift lock. The spring on the shift lock pushes it back into place. You just have to be careful not to rest your hand on the shifter while driving (a habit I have to break!).

 

So, After getting the car fired up we decided to mess around with the car a bit to see if we can get it running at least a little better before David gets back into town to tune it for me. It still had a slight backfire issue (much better than before) and it sometimes was hard to start.


Anyone else recognize those two issues as belonging to a particular issue? Yep, cam sensor issue.


If you've read my last few posts you know that every single piece of wiring on the engine that I bought, and did not just do from scratch myself, has had some type of problem with it. Well, I forgot about 1. The cam sensor extension, which did not have the two outer wired crossed over like it should have been. A fact that I didn't even know enough about to have noticed when I installed it.


Want to know what cleared up when I switched those two wires? Yep, no more backfiring or hard starts. Fires up right away and rumbles like it's pissed off at the world.


Once we got this figured out we set our sights on the wideband, which seemed to not want to read anything below 20 on the gauge. First off we recalibrated the sensor. No luck.
Then we replaced the sensor with a new one Loren had. No luck.
Now we knew that this wideband is known to be a bit finicky with how you ground it and where you get your power supply from. I had it grounded to a body ground I had another known to be good grounds already attached. I connected the power to the air bag circuit, as it was no longer needed after the build. No luck.
I went ahead and rewired the ground to the battery post and drew the power directly from an unused location in the fuse box. Again, no luck.
It seems as if I got a bad unit from the factory.


Want to know how good my luck is? I bought it last April (2016) when I was collecting parts and not expecting this build to take this long. Needless to say, the 1 year warranty is expired and I will be shelling out for a new one so we can tune this danged thing!! Less learned on buying parts to darn early...

 

So, got the new wideband in. It reads exactly the same. Triple checked using 3 different new sensors, with 2 full re-calibrations on each. Absolutely no change.


At this point I'm thinking that maybe the output wire is set at the 0.1 - 1.0V setting instead of 1.0 - 5.0V. I will be going back to the shop on Friday and hooking up the computer and checking this out. Hopefully that is all that is wrong, because I cannot even think of anything else it could be!?

 

Boring

 

So leave...

This is some adventure, hopefully those gremlins get sorted out and you get this beast on the road! The attention to detail is amazing!

 

+1

May as well give up and buy a ferd...

Spoiler alert, he got it running. The 3 miles he's put on the car have taken 3 months. Told him it would be slow

 

Keep your wires crossed that this thing will be finished soon.

Engine does sound good. Revs pretty damn fast also.

 

So says the guy tuning the car. Maybe it would be less boring if you quit going overseas in the middle of the build!


Yes, it has been a while since I gave an update... Well, I had to slow down on the build for a bit and take care of some things around the house I've been neglecting.


After finally getting all the wiring bugs figured out, David was able to get an initial tune on the car. The massively lean reading on the wideband was accurate. Two more wires crossed up in the coil harness I bought. This time just flat out wrong colors going to wrong coil. #3 and #5 were crossed up. We got a workable tune installed, drove it around the yard and it started to overheat. Well, my brand new thermostat froze shut and wouldn't open. So, we pulled it and kept on going.


It pulls strong and breaks the tires loose without any effort at all. I am definitely going to have to get some big ole' sticky tires on the car sooner, rather than later. We still have to do some tweaking after David gets back, but, it's perfect to start breaking in the car.


I do still have a few issues to take care of, and I'll try to provide more timely updates from now on. Sometimes you just get busy...




By the way, here you go.... I just couldn't resist...
