Xfi ?

[Lee Thompson]

I have a 200 R4 with a L/U convertor and I am new to XFI. What air fuel ratio is good for l/u cruising. I am currently @ 13.

I have been as high as 15.5 afr at cruise with good results. Leaner than that and mine would start to hesitate a bit. EGT read 1150 to 1200 at that range.

Thank you

I'll start leaning it out.
