Turbo Kit TurbojetK lambda emulator/ fuel controller by Jetprime for Piaggio/ Vespa 125-500cc fuel injected maxi-scooters.

The injection module adjusts and simulates the signal produced by the lambda emulator to produce a perfect air-fuel ratio. This emulator is adjustable allowing you to manually increase or decrease the fuel, this works great when upgrading air filters and exhaust systems. Throttle response is improved along with improved power delivery.

It is recommended to start with the setting 0 and go from there. On standard engines settings 2-4 will normally be optimal, with a sports air filter and sports exhaust(without catalytic converter) settings 6-8 will normally be optimal.
