The truck runs great, part throttle, wot, etc etc... however starting up (hot or cold) is the issue. I was hoping maybe someone could shed some light on my tune, maybe i need to zero a table or change some throttle follower delay times somewhere... or something like that
what it does is it will sound like it wants to start strong, rpms will jump up just like normal and immediatly shut off. Now it will start if i play with the throttle a bit, seems to like the cold starts over the hot starts right now and all these seemed to come about after installing the higher rpm and looser converter
the table i was messing with to try and get it to act right was "Base Running Airflow: Idle Airflow" (Engine>>Idle>>Idle Airflow>>Base running Airflow)
thanks in advance
