hi all,
after a comment made by Joecar in the 'wot afr' thread and a few PMs we decided a test was inorder.
I have previously set up my VE table in my standard OS for a 99 auto camaro.
I had P0101,0102,0103 set to NOT REPORTED in C6001
The VE was obviously calibrated and all was fine. (not at idle -> cheated and used STFT to find nice spark as needed car everyday back then)
NOW i switched to COS 3
I did a quick run and noticed my VE table was still slightly out, more at idle as this wasnt as good hence why I was trying to get it redone today.
This is still with the C6001 codes as NOT REPORTED.
Joecar had mentioned that these need to be set to 1-TRIP for the PCM to exclusively use the VE table over the MAF. I dont have my MAF any longer so assumed it would use VE only (even with codes set to NOT REPORTED). Joecar mentioned that the PCM will still not exclusively use the VE table, it will used some 'internal' parameters and mix it with the VE table to calculate airmass values.
The BEN values are as below
12596
I think this VE table (which was dialed in perfectly, except at idle) is different as the 'internal' parameters of the COS 3 OS maybe different.
To test the 1-TRIP theory, I changed the codes in C6001 to 1-TRIP for p0101,p0102,p0103, and made sure the scanner reported a trip. (in this case it tripped P0102). I then procedded to do another log and check the BEN values.
THEY HAVE CHANGED BUT VE IS THE SAME !!!!
12597
( i know the MAPs are small but each cell has over 20 counts, again not a lot but the car cannot be used on the road at present so this is all I could manage around my street :D )
So as Joecar originally said they DO need to be set to 1-TRIP such that the VE is EXCLUSIVELY used. I shall be doing this from now on. Hopefully thsi will help some of you guys out who accidently set P0101, P0102 and P0103 to NOT REPORTED in C6001. (the auto VE tutorial DOES NOT tell you to do this, but I still assumed you needed to, dont make the same mistake!!!)
