The most suitable setup that i have come across is
Landi renzo TN1/b regulator
YOU like it every body Recomends it go for it. But in my personnel opinion all are the same just go for any approved one from the list of ogra.
Landi renzo STAP 78 timing advance processor
The main purpose of the advancer is to advance the spark fro cng OCTANE 120 vs Petrol 87 to make the combustion efficient.
Just make sure the car does not back fire with or with out advancer. I will never be adjusting distributor or tappet for this rather i will install an adnvancer and get it adjusted .
Landi renzo LC01 Lambda control
For automatic car this is a must. FOR CVTs is a neccessity since personnaly i think the root cause of the Transmittion failure is the lack of power which people tune the car to snatch max efficiency. which eventually cause an under fueled system. with lambda stepper motor adjusting the fuel rate the cause is mininsed. hence it will not hurt the tranny.
CVT is a belt type tranny which slips when lack of power and eventually burns out.
PS: CNG bhaganay ka lay nahi hoti cost efficiency kay liay hoti hai.
Bhagani ho gari to petrol par bhagao warna cng par arram say chalao.
Landi renzo LR honda emulator.
Any emulator will work as long as there would not be a check engine light not coming at any senario.
Emulator cheats the ECU of the car by simulating different signals which are been monitored by sensors for the running of the EFI system.
PS:I like the zetronics electronis since the diagrams and details were clear and they had better funtionallity options.I have decided to go for teh combination in my steermatic to be converted next week. I lost the paper on which i wrote down the model numbers right now if i find it i will post them here. The LR electronic was very hasitant to show of details and was just like a black box which does a magic trick.I am a control engineer and i hate been tricked like that. I may go for LR Regulator since it has proved to be a good one as per masses but will take the advice as per installers suggestion and may go for any other { to avoid the 2 number thing}. Just make sure that it is an imported one and not assembled or refurbished here in pakistan.
Cheers Asif.
