Default UTEC fuel tuning question

To lean the mixture which way must I go? up or down?

Like if the default value is 1.5, and I want to to a timy bit leaner, would I make it 1.3 or 1.7? I would think that 1.3 would be leaner, but I thought someone said that to go leaner, you increase the numbers???

Down. Leaner=less fuel. The settings you're adjusting are MAF volts, which are a function of how long your injectors are being told to hold open.

If you're pulling fuel in certain spots and the value is currently .3, then you'd want to change it to .2.
