What Should i Set these at to gain the optimal performance gains?

1)Dual timing adjustment points (2000-4000 RPM / 4000-7000 RPM)
2)Timing table (+10% / -40%)
3)Dual fuel adjustment points (2000-4000 RPM / 4000-7000 RPM)
4)Fuel table (+40% / -15%)
5)Idle (+/- 20%)

thanks

I was able to bump up my timing another +5%. I went as high as +8% but it would ping under heavy load at highway speeds.

I wouldn't mess with the air/fuel ones without a dyno.

Was that pinging with 91 octane?

93 octane.

thats weird... i run 91 and i upped the timing all the way(+10%) at both the 2-4k and 4-7k range ..... i have no pinging ...

so id say for timing up it all the way , and fix ur speedo for gear swap if u need to... but other than that just use the tune that the thing comes with , its good enough and u know itll work, u dont want to screw around w/ the A/F unless are going to use the predator as a diagnostics tool and im not even sure if it does it but that would be cool, u could look at your a/f numbers through out the RPM... i thin kit does because its a digital wideband... anyone know if it does it forsure... iw ant to see what my A/F is without taking it to a dyno tune...


anywyas the moral of my story... use the performance tune that the predator comes with... change the timing to all the way up(+10%) and if u need to, fix ur speedo as well... but dont mess around w/ the a/f unless u know what ur doing

Each car is different. What works for one person may not work for another. Besides, the pinging was only at highway speeds with the a/c on. I wasn't hearing any pinging when flooring the pedal from a stop, but that might be because of the engine/exhaust noise drowning out the pinging. That's why I decided to play it safe and leave it at +5%.

I wouldn't do anything 'til you get your car to a dyno. After a baseline dyno, it will be easy to see what adjustments are necessary. If you start guessing at what the settings should be, you could be in for some serious engine damage. There is NO ONE on this site that can tell you what adjustments your car needs exactly. That's what the dyno is for. Either that or get a digital wideband a/f ratio guage, which is what I would do.
