Brand new Lotus OEM Engine Computer (ECU).
Fits 2006-07 Elise and 2006 Exige naturally aspirated (electronic throttle).
This ECU plugs right in with no other changes. Fuel and ignition changes provide small horsepower and torque gains throughout the RPM range and the VVL (big cam) engagement point is lowered from 6200rpm to 5750rpm, seriously broadening the usable power band.
