Thread: Desired Throttle Pressure Drop

    Desired Throttle Pressure Drop

    Anybody have any experience with this table or tried adjusting it? It says along the bottom that setting between 20-40Kpa improves responsiveness and I would like to know if anybody has tried it.

    I played with it once very briefly but didn't get any positive result. Very curious to know if anyone got it working

    I briefly played with this on my Cruze recently. I did not notice any effects negative or positive so I zeroed it back out how GM had it from the factory.

    I recently noticed that a 2016 Silverado that i tuned had this table populated at 2kPa. I tried the same setting on my cruze a couple weeks ago but I'm not sure I feel the difference. The setting has been active for at least a week now. Maybe I'll try it at 4kPa. I assume they must have used it on the Silverado for some good reason

    I tried 20 kpa then 40 kpa and now when I drive the car on a race track (it's a race car) the throttle response has improved enough that the car can sometimes buck because I'm not steady on the throttle. I'm installing a heal stop to help with that.

    Bump this old thread. Anyone know what this table does? Previous tuner populated it in my 1.4t sonic and I can't find anything about it. [ECM] 33462 Desired throttle pressure drop
