Need Predator tuning tips!!! Hey guys...I am heading to the track this Sunday for the first time since my header install and the predator tune. Any tips on how to tune the car above and beyond the base tune that the predator installs. I am completely new the "tuning aspect" of my car. Any help and suggestions will be greatly appreciated!!! I am goin' after my buddies 03 Cobra and I want to be completely prepared to whoop his ***!!!! <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />
Re: Need Predator tuning tips!!! The ported MAF may give you a little trouble
with KR, I guess you'll see whether or not.
It would be interesting if you could do a pass
or two with the stock and the Predator "canned"
tunes, just to see what the quantitative
improvement is.
Beyond that, I'd say to knock down your fan temps
so that you see the full benefit of the 160 'stat,
jack the spark up to +10%, and see how much KR you
get (if you can manage to see whilst accelerating
without adding some paint to the guardrails).
I'm still messing with the PE, I've put it all
the way to +5% and am waiting for it to get done
learning its new LTFTs. I think with the ported
MAF you might just want to slam PE to +5% and
see what happens (add this to the stock and
canned tune times, and we'd have a pretty good
independent picture of things).
What I'm still unclear on is, whether the PE
effects are all there right after tune install
or whether there's any subsequent learning drift;
it seems my car takes a while to "bed in" after
significant PE changes, at least at the mid-
and low-throttle end. I'm trying to see if I
can get to my "lucky 13" theory. Yesterday with
full +5% PE on the highway I was seeing 930mV
WOT O2s, which is maybe-right, maybe-rich. I
think I need a G-meter and some more on-ramp
time.

Re: Need Predator tuning tips!!! im messing with my fan temps right now so ill let u know what i get to work out, i cant seem to keep it steady under 190 with a 180* stat. i had to get something to hook my predator into the wall and the dude said something about the connection. i got it from radio shack and i can flip the head to + or - and i need to know what one i need. anyone know? something about how it goes from - to + or + to -
Re: Need Predator tuning tips!!! I ran my spark out to 10+ Then messed with the fuel. I tuned on the dyno with a wideband. Ended up at +5% fuel and a 12.9 A/F NO KR. 321rwhp and 341 rwtq <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> I was happy with that considering i only have a lid and a catback. Im getting ready to spray the car and want to run richer so im getting James to make a custom tune made for me to richen it up for the spray.
