    VCM Editor question LS 6.2 concerning diag oil pressure

    I was checking my tune as I have had some issue with oil pressure numbers. My question is I wanted to know the minimum psi numbers in the LSA tune for 2009 CTSV? The minimum numbers can they be manipulated to display wrong pressure numbers? Most tunes I have seen have the following:

    0 512 1024 1536 2048 2560 3072 3584 4096 4608 5120 5632 6144 6656 7186 7680 8192
    0.0 4.7 7.3 9.4 11.2 13.1 15.0 17,1 18.8 19.6 20.7 22.6 24.5 25.5 25.5 25.5 25.5

    0.0 8.0 10.0 10.5 rest are the same

    Do these numbers effect the read out what your oil pressure is or are these factory minimum numbers?

    Thanks,

    Steve

    Also on Oil Press Min Hyst - is this the number of the minimum oil pressure seen by Hptuner? Or is this the minimum pressure according to GM standards?

    as far as i see it the values against the rpm intervals is the pressure at which the low warning will light up, the hyst is just the variance pressure after a low pressure event before it turns off the light again, if u put the mouse on the table it will tell u down the bottom what it does

    I figured that was the case, but question will changing those variables (raising the value) cause the warning light to come on earlier?

    i have doubled mine as i want an early warning and lowered the hyst and time delay, so far i havnt seen anything odd or and issues, if u want to check it just set it to a value higher then your idle pressure then u will know if it works or not
