No bro both of them are linked with cng they have no use to petrol their work is to control gas to petrol and petrol to gas conversion and to advance the engine timing when it's running on cng
I'm interested plus I would suggest you to get it removed from your car first and than sell it as every one who is willing to buy the kit would like to see it gradually in free state than fitted in car
So better to get it removed first
