    Gen4- How to command open loop idle!?

    I have done this numerous times on the gen3 setups. I cant seem to make the gen4 setups idle in open loop. Im tuning a full bolt on silverado with a pretty big cam. Truck idles amazing when i force open loop with scanner. I just cant seem to make it stay in open loop with the tune.

    I have pe set to:

    40kpa enable
    0% tps enable (i even tried 2% no luck)
    1.00 afr commanded
    No delay with 2.000 enrichment rate

    I looked and disabled all the other normal stuff like stft openloop (which gen4 doesnt have) i even disabled ltft. No luck!

    Is there a trick im missing? I know i can disable the closed loop enable temp but the would make for a full open loop tune. I just want it at idle like the older gen3 setups. Any help is greatly appreciated! Thanks.

    I've been wondering about this also. What was the trick? I've been playing with it for some time.
