Vitz on CNG... can we avoid venturi?

I am confronted with missing numbers in my Vitz both CNG & petrol. venturi when removed, runs fine on petrol. a mechanic, this is due to increased gap between the MAF sensor and throttle body introduced by Venturi ...

My question is can we prevent venturi with a view to inject CNG throttle body?

a frnd of mine removed from my car and CNG Venturi injected directly into the throttle body by opening the blow off valve is disconnecting ... missing problem was solved by starting the engine check ... and I had burned air filters ...

Is there an efficient way to CNG operation without using the venturi?

This is not venturi issue.

i also had the same issue but the problem was found in the CNG wiring.
The Voltage was dropping for one of the piston-coil, changing the wires solved the issue and Alhmadulilah its running fine from that day onwards.

Go to some real CNG mechanic and ask him to analyse the issue. (CNG wiring is put using petrol wiring, original one, so such issue causes missing both on Petrol and Gas)

i hope this would help.
