I am new to tuning and am still working through my VE table which is coming along nicely ... most values are within +/- 5. I'm also struggling a bit with Open Loop since I do not have access to a WideBand O2 yet. I am coming to the realization that both Open Loop and PE tuning will require the WBO2 (to my knowledge they both ignore O2 sensor output). My biggest question is when is PE actually enabled ?

Okay, here is the info: I am using the 2001 Express Van as a base tune, which has the following criteria:

{B3608} Delay Before Entering PE = 65 sec.
{B3610} PE Delay RPM Bypass = 5200
{B3611} PE Delay Coolant Temp Bypass (upper) = 121 F
{B3612} PE Delay Coolant Temp Bypass (lower) = -40 F
{B3613} PE MAP threshold = 55 kpa

So is the above criteria mutually inclusive ? So in order to Bypass the 65 second delay ... the RPM has to stay above 5200 AND the ECT > 121 F AND MAP > 55kpa ? Or does only one of the above criteria have to be met in order to reach PE mode ?

Which leads me to my next question ... is there a PID to monitor/log when PE is reached ?
