The ECU Enhancement Page

While aftermarket ECUs offer the most amount of HP available, the typical owner does not have access to a dyno to tune them. They are not typically items that can be installed at home. ECU upgrades offer performance but require the ECU to be sent in for programming which cannot be removed. For the owner who wants some additional adjustable performance that can be installed and removed at home, there are these enhancements. These are the products that will alter the signals coming in or out of the ECU to achieve higher performance.

Venom 400 is a "little black box" that will hook to your ECU. It works with stock ECU or even better with upgraded ECU. It intercepts signals of the vehicles sensors and modifies them to achieve a more responsive system. It can be switched off and on for smog purposes. While it does not raise the peak HP much, it raises the lower end HP output to provide a more smooth power band, and create more low end power. See more details at the website.
