In regards to this post http://www.hptuners.com/forum/showpo...00&postcount=8 in the 3800 table request thread I finally got around to test what Chris stated was true and to no suprise all was true.
Basically I read the current file off of the pcm and 0'd out the entire ve table to see what affect it would have on
a. drivability
b. fuel trims
My findings are this:
a. the car started & idled like it always has without so much as a blip
b. the fuel trims didn't budge more than 1 or 2% in the 10 or so minutes I had the tune in for.
Threw the tune I read off of the pcm and
a. the car started & idled like it always has without so much as a blip
b. the fuel trims didn't budge more than 1 or 2% in the 10 or so minutes I had the tune in for before coming inside.
Take it fwiw guys but between our engineer saying VE is coded out unless the maf fails & me testing this theory by completely 0ing out the table doesn't boad well for other interpretation of how the code works lol.
Bottom line is if it makes you all warm & fuzzy inside to perform a full OLVE tune feel free but it strongly appears as if its not necessary nor will it help at all to do so.
But think of it this way, if the VE was important in normal operation why would they setup a VE table like the one in the stock file I've uploaded?
Have fun guys!
