What are you guys with PV, TTS or any tuner for that matter seeing for the cruising range AFR, canned map or dyno tuned. Just curious if there is a big differenc in what people are running in the M8. Thanks.

 

So Im a novice with tuning and tuning software, but I have my tune open in winpv so I might can find tables you'd like to view.

Here is the AFR table I believe?

 

Thanks, looks like that covered to lbs per sq in is 14.24 in the cruising range. Is that a canned map or dyno tune?

 

This is a canned may from FM for the cam, headers, and slip ons I run. Same setup Jamie had in their cam testing thread.

 

Thanks, just curious what different tuners are setting this table to.

 

Above 3500 most are happy between 13.9 to 14.2 below 3500 the boys around here are a little secretive.

 

Heard a couple of people say set the closed loop cruise range to 14.0, that seems pretty rich for that range but I'm far from an expert so that's why I wanted to see settings from multiple tuners to see where they are.

 

can you please tell me the formula you used to convert the numbers.


thanks

 

λ = AFR/AFR(stoich)

For regular gas... use AFR(stoich) = 14.7.

 

14.0 would likely exceed the useful range of the narrow bands (roughly 14.2 to 15.0). Likely outside the range for closed loop (assuming narrow bands).
