It was a GasItaly certified shop that did the conversion so I cannot really do the step by step. The tank and the pipes installation is simple. They spliced the ECU cables and connected each and every one to the LNG ECU, this way the LNG ECU does everything as of you are running on gas. Then drilled the plastic on the intake manifold and installed the injectors. We did a test run and fine tuned with a laptop the tuning of the LNG ECU. This is not a DYI garage conversion, but also in no way it should cost the $10 000 USD charged in the US. Well it cost $1000 including parts and labor in Europe.
