Computerised Tuning CNG??
Its about time we wake up. The car is a petrol engined car its tuned on Petrol and only a setting of the cng kit is done. Efi cars do every thing them selves, if every thing is proper (airfilter, Throttle body, and the spark plugs) In Efi cng cars some mechanics increase the Rpms for better and stable RPM on Cng but in such cases RPM on petrol always remains above the 1000 Rpm mark. (which personaly i think isnt healthy for a idleing engine)
The Computer is only used to get the car to required Rpms (it helps in acuracy)
Finaly as the topic says computerised CNG tuning, u need to have a computerised CNG kit for it such as the SIS kit in Liana or atleast the Lamda (or lambada what ever it is)
As a normal Landi renzo/Tumasato or what ever brand only needs a perfectly tuned engine on Petrol and minute idleing and gas presure settings (to be set at the best possible breathing of your car)
