I did't know V6.32 exsisted, I got 6.2 as a beta from the local Accel
dealer a month or two after I bought 6.0.
I beleive the utility can only be accessed in online mode from the
global menu.
Does swithing to TBI mode make the inj fire at twice the rate? if so
then 4 of your inj would = 8 TPI inj. just accout for the cu.in.
diff and the 22 VS 36 lb/hr
455/350=1.3 so multiply map by 130% for cuin diff.
22/36=.61 mult map by 61% for inj size increase, if you have half
as many firing twice as often.
Both of my systems are on chevy's firing stock TPI intakes, so I
didn't have to do all this. Although my maps look nothing like the
samples provided by Accel.
If any of this looks wrong let me know.
