Nothing crazy. But starting with the stock tune from the 6.0 making little adjustments like raising rpm and removing a little fuel, and just can get it to start at all. just cranks and wants to start here and there but dont. Really lookin for some help just to get it at least started so i can go from there. I know theres a bunch of people that really know theyre stuff and can lean me in right direction, any help is greatly appreciated. I can

    ls6 intake
    ls6 injectors
    and a small summit cam. ( SUM-8719R1 )

    Here is just little changes i made, nothing crazy, stupid things that dont matter like fans, tire size, gear ratio, vats.
    But trying to get it to fire i did go under engine/idle/rpm/base setpoint, and set that to 975

    and went under the engine/idle/rpm/airflow/base running airflow/idle airflow and added i believe 20% to 30% there. here is that save

    Here is a file to get you started. Make sure you find your correct injector data and copy it in. You will want to get your ve dialed in as well. You can download the bluecat trans tool and dial in your shift points. Be careful of spark knock.

    little new to it. just wanna make sure im lookin in right spot for the injector data. is this under
    engine / fuel / general / and then looking at injector control, flow rate , limits , offset , pulse corrections , and injection timing sections. is that right? i have a tune from the ls6 that had same injectors and intake, do i just copy over differences in those areas i listed? here is the ls6 file if needed. df.PNG

    You will need flow rate vs kpa, min and default pulse, offset and short pulse adder. The default pulse I change if I have it but most of the time I leave it alone. If you have vacuum reference on your regulator it will use the same flow rate across the whole table, if not then it will be sloped.

    Just wanted to write back and thank you for helping me out. was able to load data and make some changes and get it idling pretty good, will of course go further when im ready, but good idle was what i was after and you really helped me out. ...
    Thank you
