So I got results on a highway trip. But haven't been able to get anything since. My usual driving route for the past week has not resulted in an increase in MPGs. If anything it has gone down I little. I suspect my Volo chip is crap. But they were nice enough to extend my return to 90 days if I found no definite results.
Anyone know bout this? Whats your trouble shooting process?
I fear if it is then I will have to buy a MAP sensor enhancer and O2 EFIE. The MAP sensor enhancer I see as simple enough to hook up but the O2 EFIE I'm still a bit confused about. I have a 97 Accord so I'm guessing I will need both.
Anyone know how I can maximize my results for city driving? I have a dry cell with a bubbler that is connected to a hole in my cold air intake closest to the throttle body after the PCV valve.
