Gas dropped after flash

Post by groundon000 »

Hey guys I flashed my 2017 civic 1.5t cvt ex to 3psi Mishimoto with stock cvt response stock throttle response, anti knock, optimized turbo response and o2 sensor off. I have misigimoto Sri and ... downpipe. I first did 6 psi Mishimoto tune with high octane and it went from 129 miles to 100 miles of gas. Then I did 6 psi to 3 psi Mishimoto tune no high octane and it went from 100 to 90. What I do wrong? How do I fix this?

Artificial knock control I mean.

Now for some reason I got check engine light. I turned off o2 sensor.
