Summer tunes

[biker1059]

Well the weather is hot now 97 degrees. I've been noticing that my exhaust is smelling a little rich. So I went into Tuneboy and lightened up the L tables at the bottom end, 3% so far and no decel poping. Does anyone else run different tunes in summer and winter? I know air density is different in both seasons.

I've removed the O2 sensor. I kinda suspect that I've always had too much fuel in the lower L tables but not for sure. Thats why I asked if anyone used different tunes

Nope but I did modify mine for fairly rich at low rev small throttle openings, lean in mid range cruise & full power over 50% throttle
