Re: With li reducing why hasn't LPG dropped in cost?

Lucky you aren't in Australia. On fuelwatch website, cheapest 91RON is 77.7, but cheapest LPG is 79.7! The LPG metropolitan average is also more than average for 91RON.

what size heater hose for OMVL r90e?

I downloaded a manual for this converter, but it doesn't say what diameter the coolant hose should be.

Re: propane butane ratio

I found out that in the rural towns, they sell pure propane. Propane is needed for indoor stoves. The oil companies can't be bothered sending 2 tankers around, so the petrol stations get propane too. Unfortunately, not many small towns have LPG nowadays, as the number of older Falcodores with LPG dr...

Re: buzzing sound - stepper motor?

I checked all around the engine bay, there is nothing loose. It is not buzzing today, so I can't investigate further. Yesterday was an unusually warm day, maybe that was a factor.

how good is Falcon ECOLPI?

I recently borrowed an FG Falcon ute with the liquid injection engine. It was in good condition, hadn't run up a lot of km, like most LPG utes. I was astonished how powerful it was - better than the petrol Barra. Supposedly these have similar maximum power. I heard that Orbital Engine Co got a lot m...

buzzing sound - stepper motor?

A dual-fuel old mixer system. Similar to this: http://www.aeb.it/Products/Products/ProdID/13 It is okay when crusing on flat road, but when I accelerate, I hear buzzing sound. The converter was replaced 6 months ago, so I doubt it is that. It doesn't misfire or lose power, so it must be opening wide...

are "performance" ignition coils worthwhile?

The revhead speedshops sell aftermarket performance DFI coils. They are intended for supercharged engines, or those with increased compression ratio, where a higher voltage is needed.
I wonder if these will help for LPG.

Re: Do modern car ECUs advance timing when running on Lpg?

well I have a 1996 ute running on LPG. The ECU had an "LPG" pin way back then which shut off petrol injector and also advanced the spark.

diesel LPG conversion - how clean is exhaust?

The conversion is acutally twin-fuel: the engine burns mostly diesel with 20-25% LPG. So it doesn't save you much money. But the proponents claim that it eliminates soot from the exhaust, which would be a bonus when coked-up diesel particulate filters cost a motser. When diesels are now a pollution ...

Re: stalling on LPG and petrol - weird cause

Vehicle is a Holden Commodore. The purge valve opens when the engine is warmed up, and throttle position is moderate, i.e. when cruising. Older models purged simply on manifold pressure. The stalling stops when the purge hoses are disconnected or blocked, so this is definitely the cause. It did not ...

stalling on LPG and petrol - weird cause

I had a car that stalled on both fuels, so one naturally blames ignition fault. The usual advice found in various forums is crank angle sensor or DFI module. I changed both of those to no effect. So then changed spark plugs and leads, air filter, PCV, cleaned throttle et cetera. Also unplugged all c...

does OMVL converter need certain coolant?

I took my car for LPG service after it misfired. The guy tells me that the converter has corroded because I used cheap @!## coolant. Further warned me that LPG could leak into the coolant. It has an old-school iron pushrod engine, that has lasted 350,000 km on type B coolant (green, 7.5% glycol and ...

Re: why import parity pricing?

How do the prices over there compare? We have no subsidies for conversions and only a minimal discount of the road tax that everyone has to pay. To give you an idea of how the prices differ, prices here are roughly (as there are variations between different filling stations) £1.30 a litre for petro...

Very interesting - but it is for old carby cars that do not have a throttle position sensor.
I was looking for something that uses both TPS and MAP to give better control.

why import parity pricing?

Why on earth does Australia have import parity pricing on LPG? I understand this was introduced (for petrol and diesel) decades ago to encourage oil exploration. Australia has a surplus of propane and butane, so this is now not making sense. If this was scrapped, and LPG became much cheaper, then su...

is there a single mixer controller with MAP sensor?

My controller uses RPM, throttle position, exhaust oxygen sensor, and air conditioning compressor. Some use temperature, but only for switching over from petrol to LPG. The Chrysler ELB in the 70s had 8 inputs, and that was using transistors, not microprocessors. Injected LPG systems are much more s...
