The ECU page
Most owners find that the attempt to
upgrade their All Trac or GT-four, there seems to be a limitation on the amount
of power provided by the original ECU. The stock ECU has very mild
settings with economy in mind. The fuel settings are slightly rich for
added safety. A properly
tuned ECU along with the upgrade parts can make a substantial difference
in the peak horsepower. Listed below are some ECU upgrades that do not require tuning.
Also for the home tuner there are some ECU enhancements which can be
wired to the ECU to squeeze a little more power from the Toyota unit. Keep in mind
that if you want to unleash the full potential of your car, you should
move to an aftermarket ECU that takes control of all fuel and ignition systems
which can be adjusted as needed.
Aftermarket ECU systems start at less
than what you might spend for a few ECU enhancements. The only drawback is that
they must be installed by someone with technical ability and tuned on a
dyno machine to extract the full range of power.
