Poor Gas Mileage, high ltfts at low throttle? I have a torquer v3, full boltons, greentops, racetronix fuel kit.
I tuned my car using a plx wideband. Ran open loop sd and open loop maf (slp) with the same issue. I had pretty low a/f eror +/- 2-4%.
Ive gotten 120 miles/tank the last couple fill ups.
I put the car into closed loop to see if it would help any and i noticed the ltfts were up to -15% in idle/part throttle areas.
Also, my car seems to be picking up missfires in this area although it seems to perform fine.
I tried to scale down the maf table in this area and did a cold idle scan. It seems to run just fine now.
Should I listen to the narrowbands and trim the fuel here? Or is there something going on?
