Pfc Tuning

[cankas]

Ok so ive read the PFC faq sheet, under the section on tuning for fuel economy it states at the start to turn the O2 feedback off, fine with that.

It also mentions in other parts that the O2 should be on to get good fuel economy, does this mean i turn it off for the tuning and then turn it back on once i have finished?

It doesnt mention anything bout turning it back on.

Any help is appreciated.

Also where can i find a cheapish afr meter or does anyone have one i can borrow for a night or two? I know how much the good ones cost im a mechanic and im not shelling out that much for 2 nights tuning.

To get the best fuel economy you need to turn the feedback off, and tune for leaner than 14.7:1 at light throttle and cruise.
