The packaged Diablo performanc tune is where you should stop unless you have ready access to a dyno to test your results. Further advancing timing and tweaking the fuel/air mixture without being able to closely monitor the changes can result in big problems.
I have the Diablo tune on my 02 GT and it works well. It requires I run good quality premium fuel, of course, but it has been trouble free so far, and yielded a nice seat of the pants increase in performance.
Be warned. If you monkey with the performance tune parameters, you can get in trouble - detonation is a motor-killer.
As for the list of mods the Predator can do, I recommend you leave the rev limiter alone (unless you do some drastic mods to the car, your motor stops producing additional power before the limiter cuts in anyway). It can save your ass if your foot slips...
The top speed limiter is factory set to match your tires. Unless you upgrade to a higher speed rated tire, don't change this setting.
Turn off the traction control by all means if its summer or you live in the deep south like I do. If you're looking at snow on the ground, turn it back on - again, it might help save your butt. The good thing about the tuner is that you're in control...
Finally, be advised that your car could use some O2 data to keep the car running smoothly. Lots of folks disable 2 of the 4 sensors (usually the back 2), keeping the front 2 working to feed data to the computer. This often involves adding harness extensions to reach the new sensor locaions on the X or H pipe (extensions cost about $29 each).

Now i have a few more things i wanted to check out, with this tool you can change the spark, and timing, and WOT Fuel
i wanted to know if there are changes you can make to this inorder to extract some more power.
this is the list of things that can be done to the car with the Predator tuner
Dual timing adjustment points (2000-4000 RPM / 4000-7000 RPM)
Timing table (+10% / -40%)
Dual fuel adjustment points (2000-4000 RPM / 4000-7000 RPM)
Fuel table (+40% / -15%)
Idle (+/- 20%)
On/Off switch for Traction Control
Raise Speed Limiter
Rev Limiter
Re-Calibrate Speedometer for Gear and Tire Size Changes
WOT Shift Pressure
Part throttle shift firmness
RPM Shift Points
Torque Modulation (for better shift feel)
Cooling Fan ON/OFF Temperatures
Rear Oxygen sensor disable (use for off-road vehicles only)
Disable EGR (use for off-road vehicles only)
All of these parameters can be adjusted on the DiabloSport tune and/or the factory tune
thanks |
