The vehicle kits will normally be supplied with the ECU pre loaded with an initial start file.

This initial start file is simply provided as an aid for engine starting, it should not be considered a suitable final calibration for your engine.
You must be prepared to undertake further ECU calibration work to ensure the ECU files are tailored to your vehicle.
Failure to successfully complete the calibration process may lead to poor vehicle driveability or even damage to your engine.

Our Classic Fuel Injection Kits are custom built to order and to the customer general specification and as such are exempt from automatic return rights under Consumer Contract regulations.
By ordering this conversion kit you understand that further ECU calibration work will be required and the final results are outside of our control.
We cannot accept returns or claims arising from failure to successfully complete the calibration process.
