Almost done with V6 LFX to L99/ TR6060 swap

Vince of Trifecta told me long ago, when doing projects like these late models using Can Buss, VATS, Global A electrical architecture and lots of body control modules, that the more modules you change, the more the potential exists that you dig yourself in a very deep hole.

And now that you are tempted to bypass certain functions that are controlled by BCM's, the deeper the hole can get. In some cases, when you change one thing, others can change down the line. With that being said, I would think through this strategy due to the fact that you may end up spinning your wheels. Carefully evaluate these actions before going too far. Yes, you may be able to do what you are thinking but then you loose sight of working out possible elementary problems upstream and ending up with a complex mess. Take the time to understand the sequence of events from the beginning and work through them or at least understand the reason why a problem exists. You must define these things rather than bypass functions. You are so close and I worry about this potentially deep hole. No matter how it ends, you will be faced with working the early problems out anyway.

Please don't take me wrong, I am just trying to slow you down a bit in your excited effort to get this running. Your strategy may well be a means to an end but I would go back to the beginning and understand where the problems begin and how to resolve them without changing anything that is not absolutely necessary. I am a retired manufacturing Engineer and my mentor taught me this type of approach to complex problems. Vince, of Trifecta reiterated that on my project. You seem very intelligent and this is a learning process, just as my project is for me. Understand every step and evaluate each next step carefully, in order to decide if it is absolutely necessary to solve the problem and any effects it might have on other entities in the bigger picture.

It has taken me well over 9 months to get to where I'm at and only because I studied every circuit between the 2 cars, I mean every circuit, defining them and ruling the ones I could out and then figuring out the ones that were different. Comparing every plug, socket, every wire, 100's of hours. I want to see you get this! There is always a solution to every problem, this CAN BE DONE. You just have to figure it out. Get information from others, as you have and most importantly, have every schematic of both vehicles and legends at your hands for analysis. It is possible that you can navigate the way you are but I am simply discussing what I have learned with you. Again, I am no authority. I am a Camaro buddy and want to see you achieve success. You have come a long way and I'm not sure I could even get as far as you have In your project. Keep plugging away and I will follow you on the forum.

I am days away from testing my project and will keep you posted and pass on information as to how my test goes and what it took to do it. Hang tough, friend!

I love the motivation! Reminds me of my old Master Sergeant. Advice well taken. I can't do a fuel pump bypass anyhow, that wouldn't open the injectors. I'm gonna get an alldata on the 2013 and compare this last connection issue I'm getting. I've gotten to the point where the car knows the ECM and Vats are different and disabled. Thanks again for the words.
The most frustrating part is that the dealership is giving me such a hard time with speaking to tech as far as what he did. I really do not want to have to file a complaint and go over head, but it must be done.

I, too, have had no luck with getting help from the dealers. When you deviate from stock, forget it. They have very strict policies from Detroit, concerning alterations of vehicles. You just have to figure it out yourself. Other knowledgeable people on the forums, as well as tuners, can be of significant help, so long as "they" know what they're doing. Vince of Trifecta has been an enormous help to me on my project. There are a few good ones out there. Keep on truck'in!

As far as alldata, they are one of the best. I purchased a year subscription for each of the cars that were involved in my project. Priceless information and electrical data, plugs, etc.

Not sure how far you are willing to go, but I know if I had another $1700 I would get the Holley set up. That includes harness and a ECM that can run anything. They also have a LCD dash screen available that looks similar to the dash in the new stingray corvettes.
If I don't finish before I come across another $1700, that's what I will look into.

I think it's just cheaper and easier to sell and buy a factory V8 vehicle.

Not cheaper. But easier.
Aftermarket parts starts this way as do all other things. Good hearing from you Bo.

I agree with bo. At the end of the day the money you spent into this project could of cost you a brand new v8 and mods as well to add onto it. But hey its the passion you have for this so keep going and get her done. Have you consider going to different dealerships for info?

I think this thread has made it past all the opinions of price and personal preferences. But the dealer I went to did remove the system lock but they told me they couldn't get to ECM. A communications error. So I'm going to update the alldata to a 2013 so I can cross reference my slightly modified harness. All that's left is ECM. Car has been flashed to a v8 as far as programming

Why not go with the LS3?

If money was your motive, the 5.3 V8 from the Silverado would've been dumb cheap...either way.... way to go bro! I hope all comes out well!

Thought I would pass along my LFX TO LLT test. Passed with flying colors. Only a couple elementary DICs. Ran the engine/transmission for 20 minutes. Started from the car with fuel and charcoal canister plugged into the LFX engine from the car. First try. No BCM program changes made, all stock vehicle BCMs, only new LFX ECM with VATS disabled. After test, plugged the LLT back in and drove the car home. Not saying your V8 conversion will be this simple but thought you'd like to know. Keep truckin, good buddy.

Outstanding! I'm 8 wires away. I have a bit of a issue with alldata and GM parts. The harness I ordered does not match the plugs on alldata for 2013 Camaro but the part numbers match.

It's one plug next to connector x102 that I'm struggling with.

This is what I have to figure out and repin.

On the harness it's spliced from #4 X102 as seen in my photo. The harness route is what alldata has posted for 2013 Camaro. I want to go off wire color, but not too sure if I should.

Anyone with a 2013 SS manual want to upload a pic of their x102 connector that sits right next to fusebox?

I discovered discrepancies in a few wire colors myself. Went back to circuit numbers and used those as priority and followed them through the electrical schematics to the plugs to define location. The circuit numbers and where the wires go is what I used as the gospel . The factory may have ran out of certain color wire and simply substituted another color in order to continue production. This happened many times in the factory I worked in, so no surprise.
