Hello,
I am trying to tune a 2013 caprice PPV L77 with E38 controller, no matter what I do the data transfer rate is extremely slow. In the attached image and log, engine speed is not polled and is at 5 hz and works great. The other three channels (Mass airflow, MAP, O2 voltage) are polled and I have them also set to 5hz but they update maybe once a second.
Any advice?HP_Tuners_Slow_E38.pngCaprice_L77_E38_Slow_Polling_Despite_200ms_Rate.hpl
