hey guys i recently converted my Gli onto CNG .. so i thought i should share my experiance with u fellow PW's
CNG pe zaiyda farak nai para.. bass pick bohot he ma'moli se kam hovi hai .. and i think its got more to do with me adjusting with new CNG settings on the clutch and me releasing the clutch .. than any thing to do with car running on CNG or petrol... but my guess is car wont cross 130km/h mark on CNG?? wat do u say? i'm shifting its gears on higher rpms e.g. 4k to 5k rpm.. so that engine zara use to ho jaye to fast running and becomes responsive in face of overtaking dilema.. hhmm CNG cost=32k .. he installed another UNIT along with the CNG kit (lady renzo) and told me this unit is ADVANCER PLUS EMULATOR.. these days these two COME in one unit??? ( i think name is TOMASTO (spell) ..i was confuzed and i still dont think he was being honest?? wat do u say? althought the unit has clearly written on it.. advancer and emulator WORDS.. but then again these things are either chinese made or pakistani..so writing doesnt count .. but i'm very very satisfied with the connections he did.. cuz i was standing on his head through out.. he did everything so neatly that i was happy and he told me i can get back to orignal petrol whenever i want.. he will just unplug all CNG wirings .. cuz he did wiring from one GRIP to another GRIP .. no extra cutting of body parts or even wiring...
btw.. the mechanic told me there is no need to install 55L cylender.. due to following reason
50 L : capacity=~52.7kg and weight=~49kg and milage ~170km+ with AC and price=32k RS
55 L : capacity=~53.5kg and weight=~67kg and milage ~180km+ with AC and price=32k RS (no extra charges for 55L cylinder)
i dont know if these figures are correct but thats wat they told me and i went for their word as i'm going to them for tuning and regular checkups.. plus they said they always prefer installing 50 L cylinder .. and only install heavy one if customer insists.. but mostly 55L cylinder needs packing to be inserted in rear shocks of ur car..
i'll note the milage it gives me on 50 L cylender.. and then share with u guys
i'm feeling RPM drops at the moment but i think its got more to do with me adjusting with the CLUTCH than anything to do with CNG settings.. :S but once i get used to the CLUTCH then i'll surely look into the CNG settings if the RPM drop problem still persists...
oh and he said due to the settings they do on their CNG conversion.. there is very very minimal chance of BACK FIRE issue.. even if u run ur car in lowest rpms in high gears.. but to stay on safe side i'm gonna shift the gears to attain high rpms e.g. ~4.5k for every gear shift
i've been told by my friend that since my gli has only done ~700 kms so far.. so i should take it on a long trip WITHOUT AC cuz its good for engine.. e.g. take it to LHR and back WITHOUT AC so car gets some taste of long drive on newer engine and the chunks of engine that are going to trim in this initial period: get trimmed over long running instead on lower gears inside city.. hhmm i kind of agree to this theory..
oh and a few days back .. at 12am in night ...i started my car at ZERO POINT chowk and since i was in the mood of "engine-ko-kholna" wali thing.. so i took it for a test from there onwards and crossed nearlly 140km on CNG in 5th gear.. i didnt realise there was a guy (nice fellow) in baleno who saw me taking off and instantly joined me in a race.. lol it was really funny cuz we both didnt realise for starters that we were racing each other.. but then he took me over on shakarpariyan chowk and didnt let me cross him and wen he took too much lead he would stop at some point and wait for me to come from behind and then start race again..it was too much fun to race with that guy cuz he was driving very very safe and neatly.. i have to appriciate his driving skills.. and since i was on my applied for car i couldnt join him in on cutting and sneaking in from left sides but i tried my be
