I have installed Landiranzo 55L CNG with Advaceer & Emulator (Tomasetto & Lovato). But 2nd gear (low speed) missing problem both on patrol and CNG. CNG giving only 100/105km on 55L cylinder.
Previously when CNG not installed on my car, air filter was ok and there was no burn issue, but it had minor missing problem on 2nd gear, then my mechanic made some adjustment and then issue was resolved but Patrol avg was very bad only 8Km on per liter. one more thing when cng was not installed air filter box horse pipe was missing that time. at the time of CNG installation then i purchase air filter box horse pipe. but since then car still has 2nd gear low RPM misssing prblem and burn air filter issue.
