I have Civic Exi Prosmatic 2006, done 23000kms on petrol. Recently got it converted to CNG from Caltex.
The kit is LR with LR Emulator & LR Advancer STAP17.
As far as the running is concerned there were 2 problems.
1- Slow idle and dropping rpm on CNG.
2- Slow / no get up and go.
I took my car to CNG Solutions, who inspected my car and pointed out that they would have installed other electronics instead of LR. They made some adjustments and the car was performed much better except for slow idle/ dropping rpms.
After reading feed backs of different civic owners on this forum I took up the matter with my installer that the car needs a MAP-2 advancer, which they agreed to provide. After installation of MAP-2 advancer the RPM are 900 and stable on AC and in gear. However the car has become much more lazy than with LR advancer.
I just wanted to share with all of you that cars like Honda Civic Prosmatic needs special electronics (advancer) all will not work.
If any body had similar experience pls share and advise.
