the vehicle i'm tuning is an 01 s10 4.3 the computer is really similar to the v8's (i'm pretty sure) that's why i'm posting here.
does it matter if you change all of the o2 switching points to 350mv. since when you get on it, it's going to be in open loop anyway?
my o2 mv's are:
Labels 0 2 4 6 8 10 12 14 16
Rich/Lean Voltage 500.9 500.9 500.9 526.0 536.0 536.0 536.0 536.0 536.0
is that higher than most? since 450mv is suppose to be stoich? airflow mode 10 goes up to about 6500hz,so up to 10 are my low load areas.
i'm looking for dfco tuning help also. any good links would be appreciated i haven't found any good ones other than the mileage sticky
