Will fitting Vapour LPG void my new car warranty???

[cammm]

Hey guys,

Not too sure if fitting Vapour LPG will void my new car warranty???
I would like to get it done as my fuel average is 18l +


Thanks,

I'd say it will.

Unless Holden approve and fit the modification you're essentially pushing shit up hill.

Bare in mind ... warranty luck seems to be dependent on the individual dealers.

I have Liquid injection on my GTS - only have a couple of months warranty left and i have tried to get a rattle noise sorted out but get rejected due to me having the Liquid injection and other modifications. they have requested me to remove the modification and put the car to stock then they will look into it.
so yes you may run into problems esp if it relates to the engine

spoke to ezy gas and they said the new car warranty will only void the particular areas modified. They then said that because iwould be voiding my new car warranty on my engine they offer a warranty on my engine if anythign goes wrong.

In my experience, car dealers will do ANYTHING to avoid carrying out warranty work. If you're worried about new car warranty, you're best to wait until it expires before installing LPG.

Not quite.
In a "perfect" world for manufacturers, nothing would go wrong and there would be no claims to eat into their yearly profits.
But, since cars need to be made to a price to have a hope of selling, and the manufacturers for some wierd reason want to make a profit, things go wrong.
Since LPG is a notoriously "dry" fuel with no lubricating qualities, and the different combustion qualities of the fuel make the engines run hotter than petrol combustion, damage to valves and valve seats in particular is a concern.
What everyone needs to remember is that it is not in the manufacturers interest to intentionally try to p!ss off existing customers by rejecting warranty claims outright. Doing so could lose them a future sale.
Also, it is not in their shareholders interest to have an owner hold a gun to their head and expect "unconditional" warranty for considerably modified from standard vehicles. Imagine the free for all sh!t that would go on with this!
Reading various posts from numerous members, it is an area many have failed to grasp...

Don't forget the liquid systems that run cooler than vapour and have injectors that are cool when running.

Valves and valve seats should not be a problem with all the testing completed.

From http://www.holden.com.au/owners-info/faqs

Only Genuine Holden Parts and Accessories and HSVi Enhancements are comprehensively tested by Holden Engineers.

Given this, Holden does not recommend modifying your vehicle from its as built nature using non-Holden approved parts and accessories. Your vehicle's integrity, performance and safety may be impaired by modifications using non-Holden approved components. Should you proceed with modifications, your New Vehicle Warranty will not be voided. However, should a problem occur which is attributed to the modifications made, any repairs will not be covered by Holden's New Vehicle Warranty.

The bit in bold is the crucial bit because certainly if you have valve problems Holden could blame the LPG conversion for that. Anything else with the motor or even fuel system as far as it interacts with the LPG is debatable............ I think you could argue that diff and manual gearbox warranty are OK, automatic gearbox warranty could be a different kettle of fish as that's tied in with the tune to an extent, so when they change the tune for LPG that could be blamed for any automatic problems.

I might be wrong Wonky but I don't think they actually change the tune with Lpg( Liquid anyway).

The lpg injectors are calibrated as required

The liquid lpg just mimicks the petrol tune.

You can just leave it as a standard tune or retune if required with the lpg optimised and the petrol improved over stock.

No idea how the vapour systems work.

The liquid lpg just mimicks the petrol tune.

The JTG system doesn't 'mimic' the petrol tune, it fully utilises it. The injectors are calibrated so that the petrol injector pulse width can be used, thereby creating a 'mapless' system.

There is no way to tune the JTG system. As I said above, the system runs directly off of the petrol ECU. This is actually advantageous if/when you decide to modify the engine in any way. With a conventional gas-phase injection system, you will need to take your car back to your gas fitter under the same circumstances.


No idea how the vapour systems work.

Gas-phase injection systems are very similar to Liquid-phase injection systems, except that they have a multi-stage regulator fitted between the outlet of the tank and the injector rails to reduce the pressure of the LPG from storage pressure to working pressure (in lieu of an inline pump fitted inside the gas cylinder). Also, an additional gas ECU is installed which 'piggybacks' the petrol ECU (so it uses all engine input sensors). This gas ECU has it's own injection map and needs to be calibrated with specialised software. Some Liquid Injection systems are also set up in this fashion (e.g. Orbital LPi). With these systems, every car will have a different tune to match the engine characteristics.

Think of it this way: with gas-phase injection systems, you effectively have two separate fuel systems. With the JTG liquid injection system, a single system controls both fuels.
