Hi all, so I have been wanting to learn tuning for a few years now and have finally decided to jump into it. I am taking all the Ford classes at The Tuning school, and they are terrific! But they do not go over E85 in their classes. I have searched through some of the bulletin boards examples, and they have helped me a ton in my building of the tune for my car. My car is a 2019 GT Mustang 10R80 with E85, LTH, JLT CAI, 170 therm, and 47lb injectors. Could someone help me with the fuel and spark tables to see if I am correct in what I have changed throughout the tune. Or please let me know if there's things I need to change or haven't. I guess just another set of eyes lol! I will post the stock tune and my edited tune below. Any advice or learning opportunities would be very greatly appreciated! Thank you!
I'm with Pistol_91. It's a hodge podge of changes, many unnecessary, some detrimental. You really need to understand what each change is doing before making the change. Sorry but this file is a hot mess.
For your mods, there really isn't a whole lot to change man... Fords stock tune is really good. Changing injector data and MAF curve obviously is a given, stoich for e85, upping timing in a few different borderline tables will just about do it... Changing DD isn't really needed. If you're looking for more pedal input, you can just change the pedal characteristics to make it feel "peppier".
There is just a lot I personally would have left alone. Seems like you spent a lot of time on this and it really isn't needed. The OP cam angles I would only mess around with on a dyno to see if there are any real gains to be had by changing them. Stock values are pretty spot on for N/A. You changed almost all the values in the borderline tables, only a few cells really need to be changed. Idling at 900 seems high to me too but I guess that's personal preference per say.
Going FI is when a ton of changes need to be made.
Okay thank you this was what I was looking for haha. The Tuning School says to edit things such as DD, pedal characteristics, transport delay, and the spark tables (other than data from modifications such as fuel injectors or CAI). The cam stuff was not going to be uploaded because I do not know enough about that stuff I was just playing around with what HPT allows for that stuff. This is the first Coyote I have ever tuned so I've tried getting a lot of information but there's a lot of different things people have done. Tuning School says to increase stock values in the spark tables by around 3 degrees and test while adding or taking away 2 degrees at a time depending on knock sensors, but I was hoping to get some good baseline advice, in spark or fuel tables, so I do not mess the car up lol. Modular motors are very different than the Coyote platform from what I am realizing.
Got cha. Yeah the info isn't out there like GM info is. MBT should be stock. No reason to change it. Yes you want to increase spark timing in the cells that call for it across the axis (rpm x load). Not blanketing the entire table. All the mapped points have the potential to blend together. You don't want to increase ALL of them too much. There's a decent write up on here about spark timing and mapped points.
