First tuning, hopefully someone has already made a file

The attached .bin is likely a stock LQ4 / 4L80E, without modifications.

Great, thank you. I will take a look at it. I have no idea what needs to be changed for the different fuel injectors if anything, or how to change tire size in tuner pro so those are my biggest concerns

You mention EV6 injectors, but that is more the type of I jector body, not the size. Do you have brand, , size and part number? That way you can look up the correct injector data to plug in.

I guess I should have added that, didn't even think of it initially. 4 hole 36 pound per hour

Could you post the tune you currently have?

I took the file posted above and changed it for the injectors you have. I also assumed the following:

- You are using the original truck MAF sensor.
- The wiring harness and tune you are originally using were set up for a 4L80E.
- You have the fans controlled by the PCM.
- The A/C fan control is done by the PCM.
- You are running E10 pump gas.
- You deleted the catalytic converters and EVAP system.

You could always just copy the injector values over to your current tune and go from there. The tune I set up is assuming that the wiring harness is set up for a 4L80E and I've already changed the transmission shift tables and torque converter tables to account for your rear end ratio and tire size.

Thank you, that's great! I am using a BP automotive harness, the original MAF, fans are PCM controlled, and cats are deleted. The file I uploaded should be my existing bin file, and I will be loading the one you modified in the car shortly. Sorry I'v been slow to reply, I have family coming for turkey day and I'm trying to get the house ready
