Auto-LPG Conversion Thread

[tediber]

update lang hehehhee mahirap nga talga tantiyahin ang FC just by looking at the LED or even the pressure guage attached to the LPG TANK ....... anyways gusto ko na ubusin LPG ko but it just keeps going hehehehe almost 240kms na natakbo ko .... the pressure guage at the tank indicates almost empty pero me laman pa din e. isang araw pa siguro maubos ko din yan.

1.6E A/T Altis .... on petrol i know i do 8.5km/liter

I think they can if you have an open loop venturi mixer kit but if you have a venturi-mixer closed loop kit in your car, the original installer will need to lend speedlab their laptop to tune the LPG kit's computer box.

[ghosthunter]

hi niky, tanong ko lang.. how much did it cost you to have your car tuned from speedlab?

Dyno tuning rates applied. But I'll leave it to Niky to answer.

sir GH pwede kaya EROOM kits dito?

pwede if EROOM would lend their laptop. I am assuming you're talking about the closed loop venturi mixer kits.

Does anyone here have this product installed in their LPG equipped car?

FlashLube electronic kit.

For those guys who have already been using AUTO-LPG on their vehicles...

What is your vehicle and how is your vehicle doing on Auto-LPG?


As for me:
1999 Toyota Corolla GLi A/T (NAIADSS venturi-mixer w/ emulator) - doing well after two years, recently converted my korean LPG filler valve to the italian/euro style filler. Generally no problems with my auto-lpg system as long as I keep my air filter clean. One weird result of changing my filler valve, my system seems to be filling up way beyond the 85% typical cut-off which results in more LPG in my tank and added range when driving before needing to fill up.

Ferman says any SGi kit can be tuned if the vendor is willing to lend him their laptop. If it's Greenfuel, no problem, Speedlab and Greenfuel are already partners.

Standard dyno-rates should apply. My car was a test-case to see if they could do it successfully. Speedlab charges about 4500-5000 pesos per hour for dyno-tuning. We can't say it'll have the same dramatic effect on all cars... but it's a good bet that your car will run about 5%-10% more powerful after tweaking, and any "flat-spots" caused by incompatibility between the kit and your car's stock ECU can be ironed out.

Of course, I don't know yet what the effect on fuel consumption is... usually, when we dyno-tune, adjusting fueling of the car on gasoline for maximum power makes it run leaner than stock (some stock cars run pig-rich), resulting in lower consumption. I don't know what Ferman had to do with the Lynx. I'm going to ask him later.

It's not necessary to have your kit dyno-tuned. But if you have hangups about poor power or want to ensure maximum reliability, this type of tuning can refine your SGI LPG map so that your car will run as smoothly as possible, with no dangerous lean spots or fuel-wasting rich spots.

I've been reading these pages and sadly I'm just at page 60+ at narerepeat ko pa... hirap pag halo work at research hehehehehe. But I think all my questions have been answered on lpg! Love this site.

Sir Nicky usually how many hours are spent typically in a dyno run? I'm planning to get an open-loop emulator type but first I'm going to fine tune my car. Di ko na halos magamit dahil sa taas ng gas ngayon, and I think I've already skipped my last PMS. Tingin ko pa rich ang run niya.

Thx!

[niky]

Usually, an experienced operator like Ferman can finish everything in just one hour.

BUT: You'll need the following for dyno-tuning:

For older EFIs with distributor: A piggyback controller like an APEXi SAFC.

For newer EFIs with direct ignition: A piggyback controller like the Unichip, which can control ignition.

Dyno-tuning is not a band-aid for an improperly working engine... a simple tune-up and some work to fix whatever's causing it to run rich is a more cost-effective solution.

With an open-loop, I don't know if dyno-tuning will give the same resolution and smoothness as with an SGI kit (the SGI has its own computer, which varies fuel delivery based on RPM and stock injector cycles).

How to choose LPG conversion kit? This is for a 1600 cc EFI Toyota model 95

At PTT, their Italian LOVATO is P17,000

at JW, their NAIADSS korean is P28,000

The price difference is too high... where is the catch? Both are for private cars with no contract to fill up at their pumps.

If the difference were P1,000 to P2,000 i can understand, but in this case the diff is P11,000 !!!!!!!!!!!

What am I missing?

[tediber]

update lang just came from GREENFUEL .... minor calibration .... mas lalo pang "petrol" feel ngayon ang takbo ng Altis ko on LPG ..... thanks to GREENFUEL ....EXCELLENT AFTER SALES SUPPORT !!!

hirap i estimate nga ang FC ..... but for now my rough calculation is 250kms used up 36liters give or take a liter hehehheehe which would put my FC at around 6.75 to 6.9kms/liter ......not bad na din coming from 8.5kms/liter on petrol (A/T kasi e)

You can try checking the LOVATO kit is priced to include the EFI emulator?

RPXHost,

Can you provide the contact details of the PTT & JW. Seems they're not in GH's list before.

I think they quoted you are the carburated variety. The kit selection really depends on whats in the hood. Did you drop by their shops and let their techs get a look at your car.

GH might give you more info. Deep in this thread are three species. I think those shops present two of them. Personally I'm looking only at the third, the SGI kit, which has its own computer to regulate the flow. SGI is the smartest, but also the most expensive, around 40T. Also, my Suzuki APV can only use SGI, as GreenFuel recommended to me.

Thanks for the advice! Yung A/F nalang ang unahin ko i-solve. Read muna ako ng other posts uli.

I have a feeling they aren't even in Metro Manila.

Note: nothing really new of what was already posted in the LPG thread.

--------------------------------------------------------------------

Here is something about carbon monoxide poisoning:

http://www.emedicinehealth.com/carbo...ing%20Symptoms

http://www.cdc.gov/mmwr/preview/mmwrhtml/mm4849a2.htm

The symptoms in the video might sound familiar...

--------------------------------------------------------------------

Are the symptoms linked to LPG use? ... possibly yes due to the improperly tuned engines running on LPG resulting in higher than normal carbon monoxide emissions. The fix is simple, tune the engines and LPG kits to run correctly and this will result in a dramatic cut in CO emissions. Obviously any engine running improperly on LPG or gasoline or diesel will emit more CO and other pollutants.

But even then, taxi drivers who drive for eight hours will still be exposed to higher than normal levels of CO simply by spending more time on the road than other people. It can be termed as a "professional hazard" especially with older taxi cabs with defective aircon fresh air vents which don't close properly or similar circumstances which results in high CO level exposure.

Just finished 1 full tank(toroidal) of LPG... so assuming 32Lit ang full tank and I travel 247 km... so thats 7.7km/l for a Sentra Series 3 a/t... City driving unless you consider commonwealth ave a highway which I pass by only once... What do you think is my gas consumption good or bad?

Btw how would you know na empty na LPG tank mo? What ive noticed is when I switch from gas to LPG my engine dies... Muntik na nga ako mabanga kasi biglang namatay engine while traveling at 40km/hr...

[tediber]

pag nag b blink na isang LED na lang naka reserve na lang ata yun less than 10 liters na lang siguro yung

You should compare your LPG FC vs. your Petrol FC. Expect up to a 10% increase in LPG FC, compared to Petrol. I'm assuming you're using an EROOM kit (based on the roll-call thread)?

Btw how would you know na empty na LPG tank mo? What ive noticed is when I switch from gas to LPG my engine dies... Muntik na nga ako mabanga kasi biglang namatay engine while traveling at 40km/hr...

Again, if you are indeed using EROOM, you should switch fuel (petrol-to-lpg or vice-versa) when over 2000 RPM. If you're cruising at 40km/hr with your foot off the gas pedal, mamamatay nga yan. You need to rev it when switching.

According to Denso, the auto-switch function will do 2 things:
- start the car with petrol (tried and tested)
- automatically switch to petrol, when LPG is empty (never tried this - I always fill up when the red "E" light starts flashing)

EROOM user here. Very satisfied customer.
