Tuned car and now it won't start.
 

Ok I put together a tune for my car and it won't start when I upload it to the ecu. When I upload the stock tune it works; I checked the immobilizer code and its the same. I can turn the ignition and you'll here it crank but it won't fire up it won't fire up.

Does anyone know what this could be? Thanks for all your advice.

You "put together" a tune? Not sure what exactly that entails...logging I hope.

Why not just change the timing, fuel and boost in the stock map since it works and starts, then save it as "put-together-tune.hex" that way you can revert back to stock?

That happened to me when i changed from the 0008 to the 0014. it ended up being the RPM setting in the Valet mode was too low. check some of those setting if you are using a mod with one.

are you flashing the same rom or a different one?
