    Throttle shutting on C7 blower car

    Raised the driver demand torque and couple other things pretty high up and still seeing this. Logged all the calc torque stuff and not seeing anything that is near any limits to make it shut? Any ideas?

    Where is it closing, and how can you tell without having the Pedal position logged? The TPS is following the Throttle Desired Position.

    I would put the Peak Torque and MAP A/B/C DD tables back to more realistic values you don't have to raise them any where near that much to keep the throttle open.

    put all of your torque tables back to stock and raise DD 100% row just as much as needed to keep it open.

    Is there no real math to this, cant log a particular torque table, and set it to some value slightly higher than that?

    I started where you guys were saying, and it was shutting the thing.

    I guess you didnt read the part where I said I started there, last flash was just raising the roof sky high to see if it did anything different. Is this value not based on any actual data loggable torque values? I had 400-500-600-2000 all kinds of stuff in there
