Default Another ve tuning question

If the ve tables are to be treated as all the other ls1edit tables once you get the right ve calculated for your mods should you continue to mess with the table to acheive the right A/F R or should you then move on to the PE vs. RPM table and fool around with the mults to get the desired effect. The only reason we fool around with the maf table is if the maf is changed. Once dialed in we leave it alone and tweak other table/s to square away the LTRIMS. Should the ve table be treated as such? And how much effect does temperature have on the values since air temp(IAT) should some how correlate to pressure(MAP)?

If you have a wideband, or access to it, then you can continue to adjust the VE table for exactness.You would have to kick it into Open Loop to do this. Set Closed Loop Enable Temp to a value you won't see ( 180*C). For your target AFR look at the Stoich Table (F/A Multiplier table) in Edit. Stoich Value/14.7 is your target AFR. This table is Temp *C columnated.
Otherwise, I'd assume your new VE table is accurate and adjust fueling with the IFR table. I know you've been diligent in preparing your VE table.
I personally wouldn't use the LTRMs to measure the accuracy of the VE values - It's bass ackwards.
HPH. FWIW.
