Power Enrichment questions
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 ?
What I've learned so far ...
Well,
just as a follow up ... we did some experimenting with a 2000 FireHawk tonight. In looking at the PE Criteria the first thing I noticed was that
{B3608} was set to 0 (just as lextech and joecar mentioned).
The other huge difference was the {b3616} table itself. The TPS% was mostly around 50-65% TPS, very unlike the 90% in the Express Van tune.
The third piece of information I learned tonight, was that the O2 sensors do actually provide feedback during PE mode. I was mislead from other research that PE Mode was similar to Open Loop in that the O2 sensors did not provide useful data as feedback.
Oh, and I think I might have some opportunity to play with a WBO2 ! I have access to one now.
Do I need to install the software that came with it ... or can I just use EFILive to monitor/record the feedback via the Wideband O2 install tutorial found under the download section of this site ? It looks from the tutorial like it is just redirecting the WBO2 output back into EFILive into the NBO2 PID locations ... can anyone verify this ?
