    Stop.

    Never change the injector information if you didn't change the injectors. Those tables should never be touched. Put that back to stock.


    You have other issues if you are getting a crank with a no start condition. Either you have a VATS issues or a major sensor issue like something with the MAF/MAP, crank/cam sensor or similar.

    Without data logs we have no idea. And if you think it's a VATS issue, disable the VATS in the tune file.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    You'll need to try and get a new log. The log you posted is no good.

    Nothing in it is showing any real data, like it didn't connect properly. You should connect to the car again and re-poll for supported parameters under the vehicle tab.

    You can see that lots of channels are reporting no data or incorrect data if things are plugged in. Like the coolant temp and intake air temps are at -38 degrees, that's not right.

    did u write entire after VATS disable?

    why is their open circuit for both temp sensors? that will make the car exponentially richer.

    theres no RPM signal on log. fix this first
