I picked up a 2018 gt on Saturday. decided to tune it on Sunday, now it will crank no start. I put the factory tune back in same issue. I'm going to contact SCT tomorrow as not sure if the tuner caused the issue.

Question though. Before I tuned the vehicle there was an audible noise in the steering column when I hit the starter button. I'm no longer hearing that noise. Does this car have a steering column lock that could be disabling start? if that were the case would it even crank? I'm not getting any fault codes through X4 other than crank relearn.

Check fuse slot #60 its the PCM fuse. Sounds like it may be in some sort of anti-theft mode.

Do you have the enhanced security package? That has the steering column and console lock function.

They had to replace the ECM. It appears to be a bad thing to download a custom tune for an 2.7EB F150 into a V8 mustang. I returned the truck to stock, but I didn't reset the SCT to factory to kill the custom tunes. Lesson learned.

Thanks. Really enjoying this car. I DD it. I actually prefer it over the Dodge. I gave my son the 16 CO GT when he went off to the Navy.

I LOVE mine. Its my favorite muscle car so far and i had 2 s197s leading up to this, both with close to 700hp.

Im in the middle of a forged motor build so ill be going through crank relearns and "first start" fingers crossed type of feelings here real soon hahaha

However i still want a 2013 Boss 302... hmmmmmm

I've always hated the S550 cars.
Then my buddy that I worked with at the time rolls up in a '18 EcoBoost black convertible with the digital dash and new design, the 18+ Mustang front end, and I was hooked. I knew I was going to get a S550. It is indeed LEVELS above the S197, but the S197 cars are awesome in their own right. More raw feeling than the S550.

So true.. Tony do you have the digital dash?
Absolutely Dom. I needed to have that when I saw it. My buddy showed me all the different drive modes and how it changes with each, I was sold. lol
My car is pretty much loaded with every Ford Mustang option and all but one Roush option.

Do you as well?

All good bro. Plus, you drag yours, so you want the less weight. Mine is just a great day street bruiser.
