SD check question
Vehicle=2002 Z06 7 pounds of boost. 60 pound injectors on hp tuners
-followed the help file for how to sd tune.
-i have this question though my stoich afr is 13.00317
under the PE EQ ratio vs RPM i put in my desired af which was 1.130
in the open loop EQ ratio it said to put in 1.00 across the table.
is this right? why the two different ratios's for afr. and also i can only find the primary VE table I don't know were the secondary VE table is

your stoich should not be 13.0, something's wrong. everything else is based off that, so fix it first.
PE on 2barOS' is used briefly when you're on it more than just tooling around, but not in boost yet. there's also Boost Enrichment table that controls your target AFR under boost.
when you have multiple choices for target AFR, ECU picks the richest one.
your car has no secondary ve table, that's only older cars

what should my AFR be. i have read around that 13.1 is good but i was not sure. my mail order had 14.768 or close to that, i loged ltft last night with the maf hooked up and most trims were -8 to -12 smilar to the log below
also in my wide band log seems like every cell from 45 kpa up is 7.5-8.8 and my cruise cells are 20's and 19's
it seems my head is spinning w/info. I don't know to start w/sd or to adjust ltft's. looks like i just wasted 1 hr logging today
