Aftermarket engine management UTEC

[user1629]

Out of the box the EVO UTEC is one of the most powerful ECU's on the market. It combines a fuel computer, ignition timing computer, electronic boost controller, knock detector, data-logger, launch control/flat shift controller, immobilizer (with valet mode), nitrous oxide controller, water injection controller, water spray controller, all in one plug in box.

Ignition Timing Control
The EVO UTEC has its own injector and coil drivers. Unlike a pure piggyback, the EVO UTEC actually drives the car. When you decide that you want to run 10 degrees of timing advance at 4000rpm, the UTEC fires the coils at 10 degrees BTDC. This level of timing control is impossible with a pure piggyback. Most piggybacks "control" ignition timing by modifying the crankshaft and camshaft position sensor signals before they enter the ECU. You don't actually program a timing value but a timing offset value (positive or negative) that is than applied to the timing that the ECU wants to run. That works fine in a car with a static, unchanging timing map. Unfortunately, today's cars have highly variable ignition timing maps. So you are applying a static offset value to a changing timing map. The result is, you never actually know what timing you will run. The UTEC eliminates the guess work and gives you the control you need without making you jump though hoops.

Convenience
The UTEC has the ability to hold 5 different user definable map groups. Each map group can contain a different fuel, ignition timing, and boost map. All of these selections are available at the flick of a switch. One of the key benefits to this system is the ability to run different mapping strategies for different gas conditions. Typically, you'll setup your primary "daily driving" map in position 1. You can then use maps 2-5 for various levels of boost or for optimizing the motor to run on race fuel. It is not uncommon to see gains of 30-50hp on a motor using a race fuel tune. The UTEC allows you the flexibility to take advantage of every situation

This ECU is in perfect condition. Retails for $1049 USD, selling for $750.
