Re: pcm adjustment

i been diving it for over 2 years, Not sure how i would know when the converter locks up. My reason for changing the ratio in the PCM is the gas milage is not good, Around 12mpg. I think maybe I am never getting into overdrive because the ratio and the computer are not working together, I don't have a tach
