The engine is a 2013 LC9 from a 2013 Silverado. Twin Turbos, stock cam, 6 spd manual. The E38 ECM is from the Silverado and I'm not running a TCM.
I've been chasing an issue with the throttle will unexpectedly close while under power (usually under boost). I've been doing some MAF tuning and I caught it twice in the logs. There's another weird thing that happens after the throttle closes...most of the PIDs in the log drop out. The first time it happened, my tach stopped reading as well. It doesn't happen often but I can't seem to find the pattern.
I've attached the two log files and the tune from the second run (the only difference between the runs is the MAF table). Does anybody have any ideas?
Look at the following time stamps:
MAF Tune_A 00:05:18:014
MAF Tune_D 00:05:22:360
Thanks in advance.
