Haltech Platinum PRO Plug-in ECU for Honda EP3 (HT-055047)

Haltech Platinum PRO Plug-in ECU for Honda EP3 replaces the factory computer entirely while using the factory header, harness, and sensors. Honda EP3 and DC5 (03-04). Manual transmission only. Unplug the stock ECU, plug this in, and the car is on full standalone management with the loom untouched.

What You'll Feel

Factory drivability with the ceiling removed: the stock harness and sensors stay, but fuel, ignition, boost, and auxiliary control become fully programmable, tuned to your injectors, turbo, and fuel. Honda engines carry their power up top, and standalone control of cam angle and fueling through the whole range is what makes VTEC changeover seamless instead of a switch.

Features

• Plugs directly into the factory ECU header, no harness modification

• Fully programmable fuel, ignition, and boost control
• Data logging and CAN expansion support
