With the Predator can you view live KR number?

Yes, I've done this and used this as the basis
for fiddling the timing / fuel around.

 

Yep!

 

thanx for your reply, I started the tuning and put the spark adv. to 8% and PE at 0% it read 1.67% at WOT. If you put the PE to the negative side will it help get the KR percent closer to 0%? And what is and acceptable KR percent?

My recommendation is to set the spark advance to 10%. Then drive and see how much KR you get. If you get more than 1 or 2 you should add (+) some fuel to the PE. If you get zero or close to it, try leaning out the PE (-). When you have leaned out your PE and you hit 2% again, just go back one notch on the PE. The idea is to have the full 10% (2-4 degrees) of advance and close to zero KR. You should be able to go leaner than stock PE with 10% spark advance on a mostly stock car. If you are modded, recommend getting your LTFT's right before tuning WOT.

 

With modifications that I have my KR is around 3% at WOT. With spark advance at 10%. For a cure your saying to put PE on the positive side not the (-) side until KR reads less (0-1)%. This is my first time messing with all of the paramaters and thank you for your help.
