Re: Astra Koltec Filters

Agreed with Bri. It can be easier to remove vaporiser and/or vaporiser bracket bolts to allow a bit more room to access the liquid phase filter. In fact on some of them the bracket is in the way (not enough clearance between bracket and filter housing) to change the liquid phase filter if you don't ...

Re: LPGtech software only in Polish

Yes Bri, LPGTech ECUs are locked to the language of the country that they were intended for sale in. Actually it's the software that reads the firmware of the ECU (that was intended for a certain country), it's the software that's used on the laptop - But the effect is the same. You didn't buy this ...

Re: Astra Koltec Filters

On a lot of Koltec systems the liquid phase filter is very close to the reducer but difficult to access being both below the reducer and between the reducer/bracket and firewall. If it's down on power and making a hissing noise I suspect the problem is more than just a clogged liquid phase filter. A...

Re: Advice please!

LPGShop and TinleyTech are both good suppliers of Faro fittings. Yes there's a great range of Faro fittings available, some of the most basic such as Faro to copper adapters have been around longer than most other types of Faro fittings. It was always possible to get from Faro to any other type fitt...

Re: Advice please!

Strictly speaking Faro threaded connectors should be fully tightened before Faro pipe is attached or Faro pipe will rotate with the fitting and kink. But Faro will rotate on the fitting when the Faro pipenut is slack. When you've become accustomed to using Faro ends in olive fittings you might not s...

Re: Advice please!

The Faro fittings are something you can use with confidence when you've done a few, I've done many thousands and now they're something I can fit in a few seconds and know there won't be a problem. I do tighten them to the extent there's some 'digging in' but I prefer the (usual) brass to brass (incl...

Re: Filler through body removal

The fill one way valve in a multivalve nearly always works. The fill one way valve on a 4 hole tank is a bit less likely to work than on a multivalve because a lot of installers over-tighten the fill valve during installation, it fits into tapered threads, the internals are then slightly crushed and...

Re: Disco 4.4 V8 System Too Lean EML

Interesting that the smoke test revealed manifold leaks (which would be vacuum leaks when the engine is running). Where exactly on the manifold were the leaks?

Re: Hydrogen for LPG fantasy?

Apparently hydrogen can cause problem for metals such as metal injector bodies and more importantly such as metal tanks, it can (forgive the term if it's wrong because I'm not a chemist) 'hydrogenise' such materials (change the chemical structure) turning them brittle. Probably not much chance of an...

Re: Stag Calibration

The engine isn't running in your screenshots but there are a couple of things to note... The very high gas pressure reading of 3.07 bar likely points to a reducer problem (in which the gas entry valve internal of the reducer continues to allow a little gas to flow past it even during over-pressure s...

Re: Condensation in car possibly from LPG tank?

Tanks can get cold when drawing gas from them even though liquid gas is being drawn.. As liquid is drawn it creates more volume for vapour, so for vapour pressure to remain the same some of the liquid has to boil. Not a very pronounced cooling effect though, unless booting a very powerful vehicle wi...

Re: Advice please!

It' a good idea to tighten olive joints onto polypipe fittings (the end fittings that emulate copper pipe ends) tighter than you'd expect to tighten olives onto copper pipe. I tighten them easily enough that the olive crushes the brass a bit, if the olive will slide off the brass when disassembled i...

Re: Interfacing AEB Type LPG resistive or voltage senders/ sensors to your fuel gauge.

On some you connect the white and green to the sender for a 0>90 Ohm sender, just the white (isolate the green) for a 50 Ohm sender, the black from the sender goes to earth. One of the points I was getting at above is that the voltage divider circuit made up from the sender unit and the ECU internal...

Re: Stag Calibration

LPG systems don't go out of tune by themselves - The state of 'tune' is the calibration settings stored in the ECU. For an LPG system to be out of tune it was either not tuned properly in the first place, or something in software settings is enabled which allows the ECU to adjust it's own tuning cal...

Yanks refer to 2-strokes as 'pingers'. An engine that ''lives or dies depending on its exhaust system'' as someone once remarked.

Re: General mapping tips?

I convert a lot of Nissan Elgrands to LPG. The main issue with Elgrands (petrol or LPG converted) is that they have catalytic convertors in series, 4 in total (2 on each side of the engine) because the engines are V6's. The issue is that front cats break up, usually front cats won't block themselves...

Re: Interfacing AEB Type LPG resistive or voltage senders/ sensors to your fuel gauge.

1. Like it says on the tin, only reads reserve or above reserve. 2. AEB most likely mean their 1050 sensor for LPG applications (but see 3B). 3. On most tanks/valves the clockwise position for the sensor will denote full, anti-clockwise empty. Some tank valves work the opposite way (notably stand up...
