FUEL TYPE · LPG / CNG
LPG tuning
LPG (Liquefied Petroleum Gas, also called Autogas) and CNG (Compressed Natural Gas) are alternative fuels widely used in Italy, Netherlands, Poland and Turkey. Most installations are bi-fuel kits — the OEM petrol fuel system stays in place and an LPG/CNG system is fitted in parallel. Tuning the OEM ECU after conversion preserves power and prevents the lean-knock pattern that destroys engines.
Why lpg / cng tuning responds the way it does
Stock OEM petrol calibrations run too lean on LPG/CNG, which raises EGT and causes knock under load. A proper LPG/CNG calibration richens the mixture, retards ignition timing, and adjusts the lambda target window.
Services applied on lpg / cng tuning
LPG/CNG installations typically use an aftermarket controller (BRC, AEB, KME, Vialle) that sits between the OEM ECU and the gas injectors. Some modern installations integrate fully with the OEM ECU — those need calibration patches similar to E85.
