this is faiq from karachi. i bought vitz 2004 abt a month ago.
installed cng kit on 28th november from jilani cng.
the results have been very mixed so far.
following things were installed.
landi renzo cng kit cn-04
landi renzo emulator
landi renzo 100/2 advancer
50 kg cylinder
problem is that i m facing check engine light issues.
mileage has been gud approx 130km with 60% a.c
changed the advancer twice.
used the emeregency port too. i.e used without advancer. (no check engine light issue).
after sometime jilani cng changed my advancer to neotek map2 advancer.
check engine used to come and go.
slow pickup but smooth. top mileage 120. mileage 120km
now i am back to landirenzo 100/2 stap advancer.
everyone says check engine light comes on vitz on cng. although i think its some technical problem or installation problem.
on petrol no check engine light.
what should i do and where should i consult in karachi.
second issue is that when i bought the car i faced some knocking issue. when i used to put the car in D. I used to get some knocking sound in the initial pick then all normal. after following a hard reset ecu steps, that problem went off. and the car was normal. i noted that the petrol tunning was lost as well as cng tuning. but after driving for sometime on petrol the car became normal. but for cng i had to retune the car. and then things were ok after that.
2 days later i again got the same knocking issue. i again reset the ecu again it was f9. but after 3-4 days i m facing same issue.
althought the car runs f9 but i dont like that knocking sound on initial pick. i hope u people understand.
so please do let me know abt the check engine light issue. jilani has said the car seemed to be f9 on neotek map2 sensor and has suggested me to go to neotek. i first wanted to discuss with u people and get some expert opionion. and please do tell me regarding the knocking.
i also want to inquire regardign the landi renzo stap 100/2 advancer
i can see some setting pins 1 2 3. i read that these are advance degrees. mine is set at the moment to 1,3 on 2 is off.
can i change the advance degrees . will increasing or decreasing the degrees is dangerous for the car.
sorry for a long post.
