7AFE swapped into corolla 1998

[salal777]

k thanks to both of you for your help but since both of you are divided on which one is better for my needs, im gonna source outside help. thanks nyways though.

[Vaqas1]

No we are not divided its simple. If you need it for CNG Only distributor one is more suited and for Petrol the coils ones as it contains lean burn function for better petrol consumption plus the power of this coil ones were further reduce for economy.

So for you distributor one will be more suited.

[SER_GTR]

Go With Distributor One Type.......Forget The LEAN Burn...........!!

There Are Sensors Involved In LEAN Burn Which U Will Def Not Find Here Also.....!!

New Steering Column. Its an adjustable one and comes with 4 Spoke steering with Air bag (AIR BAG Works as per pathan sb he says this one did not come with any wiring and i also failed to locate any wiring for it hmm does it work with impact of the steering column?).

Wiper Controls with intermission timing options.

Nice addition.

[Vaqas1]

Few Updates.

Got the thermostate changed to a new one. The old one did not shutdown properly at 82c just little below it so ecu use to keep my rpm at 1000. Had a option of a qabli one but Saw this one with Aijaz autos its a japanese for just around 700Rs brand new.

Also last week my CNG kit started to freeze up (See the pic) in winters so connected water pipes.

Pics.

You Live In Cold Area....!!

[Vaqas1]

Oh Yes ISB is cold. I was goin at 110 KMPH at 630AM on ISB Expressway when this happend :p.. I noticed RPM Dropped when i left accelerator and I knew this is what has happend and when I opened bonnet this is what I saw

One thing i Noticed after connecting hot pipes my gas consumption improved soo much. My car is driven for like 140 KM and still over 90 Bar gas left :p.

I Am Tuning My Ae101 On Gasoline Nowadays....!!

CNG Crisis......!!

Done With Longest DIY ever...8 Hours Straight With Just 15min Lunch break....!

[Vaqas1]

But once your car is cng the petrol performance gets very bad. My 7A was doin over 14 KMPL on petrol when I swapped but now I think its not doin more than 10 KMPL.

But the way CNG issue is goin on I was thinking of swapping the tabular intake 4EFE :p.

What have you done in those 8 hours?

I experienced an LPG regulator freeze over in karachi, That car actually stalled out on the test drive. I will suggest you check the level of the system, if the regulator is sitting close to or at exact level of the radiator cap - lower the regulator. This car was a mercedes benz 230E W124. The regulator actually had ice frost crystals and was dripping water when it was thawed out. :D. It was using a correct LPG suction venturi made by Lovatogas Italy.

[Vaqas1]

There is a pump in ISB which claims he is giving LPG to cng customers and he did an experiment and it worked so now his CNG Plant is not running you hear no noise only a truck parked outside with full LPG is what filling the CNG cars. When I got the cng from that pump which he claims is LPG than it started to freeze up all the time before or even last year in weather much more cold than this my cng kit never froze.

Can he be true?

I Don't Have Much Time To Post Pics Else Would Have Posted It Here Also....

In Short....The Whole Intake Mani Cleaned....Full Of OIL And GUNK....Never Cleaned Before..L-Key nuts And Bolts Are Speaking Out Load They never Ever Get Opened Before.......

PCV Was Broken......TB Cleaning...+ ISCV Clean service Tested + TPS Calibrated + Injectors Cleaning Testing With New O Rings And Seals + Spark Plug Cleaning..................!!

This All Took My Straight 8 Hours Giving Me Back Stiff Back And LEGs :\

No One Even Bother To Clean TB Before......It Took Me 2-3 Hour To Just Spray A Degreaser And Then Clean It With Petrol....It Was MESSED Up

I Will Be Tuning It On Petrol Once And For All

[SER_GTR]

True That You Can't Tune It All Well on Both....You Do It On Petrol...It will Mess On CNG.....(Timing Is Biggest Pain )

You Do It On CNG......It Will Knock On petrol.....!

Venturi Also effects Performance on Petrol Blocking Air....!

Looks Like GOVT Is Onto Something To Introduce LPG As Big Commercial Fuel And Get Rid Or LIMIT CNG....!

LNG Was Considered Before But Never Worked Out....Lets See What Happens...

LPG running on CNG Setup......I Have No Idea But The Freezing Effect Is Possibly A Clue Of LPG

CNG Didn't Freeze Like That......Your regulator Was All Frozen......!! You Better Know Is That Outside Temp Which Freezes Regulator Or It Was Your Fuel

I will be doin the same very soon. I am sick of this CNG saga if this didnt end i will tune my car on petrol. I found a guy who got ultra sonic machine in ISB and will be remove the venturi, getting the time set to petrol specs and cleaning TB + Adjusting spark plug gap.

Do share the results, i hope its giving better mileage now

Haven't Tried It Yet As Car Is Still Under Work.....Timing Will Be Adjusted Along With New Plug Wires And New PCV Valve..!

Car Is Surely Performing Well ...Engine Sound And Throttle Response Is Totally Different In Test Drive As It Was All Messed Up Before....!
