    2015 Mustang GT Twin Turbo Tuning

    Ok this might seem like a really stupid question but I cant figure it out for the life of me and figure I need to just ask. I am trying to find the main spark and fuel tables on this car and I CAN NOT FIND THEM! I am running DW #78 injectors and have already input all the parameters but I can not figure out where to make fuel adjustments. I have looked everywhere and can not find a base VE or SPARK table anywhere!! I have tons of previous tuning experience with other systems but am new to HP Tuners. If anyone can help id greatly appreciate it thanks!

    the newer ford PCMs are not something easy to jump at, torque based system is not a walk in the park.

    your timing tables are borderline and MBT

    depending on your cam position which puts you at different mapped point on the S550 you have around 10/12 active tables

    your fueling is all MAF based yet with a boost application there will be changes needed to be made to your speed density inferred tables for boost

    TT is not the best place to start learning Ford's logic...

    Trust me I had no idea it was so much when I first decided to take on this task. I'm actually very comfortable tuning cars though and have been doing nothing but research since I posted this. Many things are still cloudy but I'm now getting a grasp of how the system works. If you have any beginning articles/videos/documentation anything please feel free to post I've found quite a bit of info here though in this forum.

    Can you post the current tune file and I’ll see what you have going on?

    Absolutely, but please keep in mind the ONLY thing I have adjusted here is my injector size because it's the only thing i felt 100% confident in. Any suggestions/comments will be greatly appreciated and taken in. I am just trying to get a base that will set me up for proper tuning it seems there are a TON of settings that need to be changed from what I have been reading. Here is the file

    DW78Injectors.hpt

    Thank you sir will be checking out and going through all of these now! This is really making a lot of sense to me now and it's quickly becoming not as overwhelming as it was at first.

    Also, doing some logging today before I switch injectors in a few minutes what do you guys think is most essential for these cars? Currently building my channels but figured I'd ask for extra input.

    DW78Injectors base.hpt


    very rough base file so you can get the point...
