PROSMATEC = Progressive shift management technology
this answer simple
Yes, there is no problem with Honda reborn on CNG but the person who is installing the kit should understand the technicalities. I have Honda Civic 2008 vvtei oriel prosmatic on CNG and its running perfectly. I never had a problem. I have installed an EFI kit with a Lambada censer. It gives me around 125 km in the city and around 175 km on the highway with a cylinder capacity is 55k. Using this system, you should be careful with the air filter and cleaning of the spark plugs etc.
In my opinion, Altis cruise tronic failed in Pakistan due to its high price. Buying power of people in Pakistan is very minute and whoever is able to afford such vehicles would rather switch to Honda Civic Prosmatic etc as Toyota's reputation has been damage due to the braking system of Corolla. This perception mixed with the high price might have played a mojor role in the failure of altis cruise tronic in Pakistan. Note: This is completely my opinion and facts might prove to be the very opposite.
