Stu what brand is your A/F ratio meter ? I bought the latest Innovate Motorsports MTX-L and the instruction say the sensor needs to be 24 inches behind the end of the collector to get an accurate reading .



Yes the meter was run from the sensor up through the engine compartment and out the hood. Then into the interior where you can watch it as you drive.

Right now it was reading 13.00 to 13.55 when at freeway speeds but dropped to 11 to 12 at low speed. This will again need adjusting to help the low speed ratio.

Even not perfect the car ran 10 times better already! Keep in mind i also have a way to large cam profile that i am sure is hindering any low speed performance.



Sru I was talking about your sensor being mounted in the collector where it is , the directions should have told whomever installed that were to put it , the one I have the sensor needs to be mounted in the head pipe , not the header.
