Prerequisite Step: ECU Removal & Shipping
Before getting your hands dirty while under the hood, there is one prerequisite step. Prior to turbo kit installation the ECU (Engine Control Unit) needs to be removed from the car and shipped to Turbonetics in order to load the new engine management program. This program is tuned specifically for your car with this turbo setup.
NOTE 1: You’ll want to perform this step just before you are ready to start working on the car. When you receive your ECU back from Turbonetics, it will be re-programmed for a turbocharged engine and therefore will no longer work properly with your naturally aspirated “stock” engine. The included ECU return box kit (P/N 11103) includes a pre-paid Fedex shipping label for express shipping, so you can expect to receive your ECU back in 2-3 days.
NOTE 2: If, in the future, you choose to remove the turbocharger system (for example, before selling the car), it is possible to re-program your ECU back to naturally aspirated “stock” specs. At that time, contact Turbonetics’ customer service staff for details.
