Hi
I have a 03 Silverado 5.3 Im in the process of supercharging. Ive installed headers and exhaust. Upgraded fuel system. As I struggle a bit learning EFI Live Ive not installed the supercharger itself, and are using stock injectors and fuel pressure.
As I have problems quoting text from the summary notes(norwegian character set seems to do strange things). I will just copy some of the text.
------
6. B3616: PE Enable: make sure PE enables as load becomes significant
(e.g. below 60% TP below 3200 rpm, 35% TP above 3200 rpm).
-------
After reading this, my understanding is that PE should be used for all significant loads.
-------
PE Mode/WOT:
PE Mode is best performed utilizing 100% TPS (WOT). This is because a number of Fuel Dynamic Parameters are kept steady and constant (evaporation, cylinder wall-wetting, etc). Also, a steady 100% TPS insures accurate computation of the MAF Airflow. Avoid part-throttle PE Mode Tuning.
-------
But after reading this later text, my understanding is that PE is only for WOT. Whats correct?
Then I somwhere read that high postetive fuel trims are no good. Since mine are pretty high, I do not know what to do. Please se attached screenshot .
