Default Another Predator Question

I installed the perf tune and then took some LTFT #`s and sent them and the "installed" tune to DiabloSport. The instructions tell you to go to "troubleshooting" and "save current data" to get the installed tune. My question is this - when you save the installed tune does this overwrite the factory tune that was saved the first time the Diablo tune was installed or is the factory tune ALWAYS saved??? I think Im going to send them the current tune for another tweek. Im still seeing slightly pos. LTFT`s - they are 0% at part throttle highway cruise but as soon as it gets a little throttle they go to +.78% or +1.56%. Needs a little adjustment dont ya think? If the PE parameters are adjusted, do they only affects WOT?

Thanks for the help

yea pe only effects WOT. what u wanna do is get your rpms at like 2500, cruise in 4th gear at like 50 or so and go where u can stay steady for about 10 min or so. for the first little bit get on the gas then off then on, dont stay too too steady. then after doing that for about 5 min, and i mean just let off to slow down and then get back on it and u know. then cruise at steady rpm. i usually do it at like 2000 rpm, put it in 5th and go 60 that will do it. just make sure the car is pleanty hot enough. yes your original tune will alwyas be there, dont worry about deleting it cause it will stay. any other questions?

thanks for the 411. What LTFT #`s am i looking for after the procedure you described. The way I understand it - it should be slightly negative at part throttle going to 0 at WOT
