36C to 39C ambient temps. CEL "11A002 High pressure fuel, plausibility Pressure too low."
Error caused due to DME load >170%, which appears to be the threshold that caused HPFP crashing as HPFP not keeping up with intake air mass. HPFP recovers when load <170%. In this run, manual shifting from 2nd to 3rd gear caused engine lugging with the 3rd gear at ~3200RPM, load was >180% which saw continual HPFP crashing (load act. >170%) for the rest of the run.
