Thread: Scaling my tune due to maxing out timing based on cylinder air mass

    Scaling my tune due to maxing out timing based on cylinder air mass

    My truck is running great I have my tune pretty much dialed, but when I'm in the boost it maxes my cylinder airmass out to about 1.37 or so. When this happens my timing drops out. I don't have a data log to post up right now. But I'll add one later. I'm running ID1000s and using the scaling information that is provided with the injectors. I think I understand the idea of scaling the IFR and VE table. But not really sure what to do since my IFR is scaled using ID's scaling numbers.

    Setup is a
    iron block 6.0
    9.3 to 1 compression (forged internals)
    LSA heads
    Long tube headers
    BTR 3 Blower cam
    ZL1 blower and lid
    dual row intercooler and fans
    ID1000 injectors

    How much more room do you need? Are you close to max RPM/airflow when this happens?

    On mine it uses the last line of the spark table when I get over the max airflow row. Is that not what yours is doing?
    Post a log and tune if you want help

    I will test that...for some reason my minimum allowed timing was set at 15, which isn't stock. But I will test this out when I am able to load the new tune with my minimum table set to stock numbers
