Hello All,
In honor of Father's day and the summer solstice, I have decided to do whatever I have to do to get my beautiful Solstice GXP back on the road again.
So here's the short version. Last year, I had a new engine installed. You can see here for the details. I had such high hopes. lol
However, the Stupid SOBs that installed it F'd my car up so bad that I've mostly just parked it ever since. MULTIPLE safety issues.
It was 2020, and like most everyone, I had bigger problems. Now, I still have problems, but it's time to get her going again - Before the next shutdown.
Now, I know that most issues that happen with these cars are covered somewhere in this forum, so I apologize if I post an issue that has been covered a million times.
I will try to stick to issues that seem pretty unique, and if you've found an answer just post a link, please.

Engine Tune: The Engine I had installed is this one. However, based on this thread my understanding is that the engine is actually a LHU 2.0 engine with Opel injectors and a k04 turbo.
So, She needs a tune.
I attempted to avoid this by directing the mechanics who installed it to switch out the fuel rail, etc, with the ones from the original engine - but they literally did the opposite of almost everything I specifically asked them to do. More on that later in another thread.
So, I can tell it's running rich now and I have barely driven it for fear of damaging it. It had a tune before the new engine was installed, but I'm not sure what because it was installed by a previous owner.
I would prefer a Switchable tune (like the trifecta?) So I can switch from daily driver to Fast as F*ck when I want. I would also like one that I can upgrade as I upgrade components.
I'm not interested in E85, but the windshield washer fluid injection systems intrigue me.
What is the safest way to do this without blowing my new engine up during tuning?
What says the wisdom of the forum?

Wheel Wells Rubbing: Title says it all. Before the install, No Rubbing. After the Install, the Tires are rubbing on the wheel wells whenever I turn. I can see the rub marks. There's cracks and pieces sticking out.
Why would this change with a new motor install?
How do I fix this?

Rear Back up lights not working: Again, Title says it all. Before the install, they worked. After the Install, Nada.

Horn - Intermittent failure: Before the install, it always worked. After - sometimes it does and sometimes it doesn't.

There's MANY other issues caused by the mechanics who did this work, but I only want to cover the ones that have been preventing me from driving the car for safety or other reasons.
Please, help me get her on the road again!

Different engine meant jacking with the main wiring harness. That could be the source of your ongoing electrical gremlins. Good luck!

Sorry if this is obvious but I can’t seem to find it.
Where are you in the world RION?

I ask because it may be worth going to one of the experienced vendors that can work on this car to chase down and repair your issues.

each one of them is needing much more fact finding and a lot of questions / back and forth to get closer to answers..

perhaps once the forum knows where you are a member local to you can make a recommendation on a competent shop?

Others who have done this swap reported no electrical issues. I wonder if the mecan'tists just...didn't plug them back up.

Huntsville Alabama.
I can't find decent mechanics, period - much less a specialist.

Well by my super rough googling you are about 6 hours away from DDM Works.
If Dave doesn’t think it’s in his wheelhouse for his shop to do the work, I am willing to bet he knows someone who could? Not saying it would be cheap mind you.
Certainly worth a call to ask.
It certainly seems from your litany of issues it may be worth it to give an experienced pro a shot.
Just throwing that out there.

What is the relationship between DDMWorks and trifecta? My car doesn't have a stock lnf engine, so I want to be sure my tune accounts for that.

Trifecta has suggested I try a stock tune. I'm worried that may cause problems due to the Opel fuel rail the engine has.
What do you folks think?

Should only make a difference if the injectors are different sizes (flow rate).

Find someone with hptuners in your area, whether it's a shop or a regular joe and have them figure out the fuel trims are on your car. If they're pegged -30 then the car is running rich. Otherwise you have no idea what's going on with the fueling.

Does anyone know of anyone in the North Alabama area with HP tuners? :)

I was actually able to get DDM on the phone! I think they are going to be able to help me move forward!
