Predator tuning with a wideband sensor?

[Dave0803]

so what is everyone running on there a/f and spark advance? I looked at mine ofter instaling the diablo tune and it shows them both at 0. The only thing I noticed the tune did was raise idle speed and change the cooling fan temps.

Go ahead and max out the timing. A lot of people don't realize that the predator timing adjustments are percentages and 10%(max) equals about two degrees of advance, not all that much. I maxed mine out on day one and drive in hot south texas weather on 93 octane. No problems yet.

this is right. 10 percent timming is not much. your a/f ratios are good so you should be ok witht he timming maxed on the programmer.
