Re: tank on car roof

The 'code of practice' isn't law anyway, it is just a trade body's self imposed stuff, frankly it mostly refers to nuts and bolts common sense type stuff... A vehicle could pass a 'code of practice' test yet be totally undriveable (and dangerous to drive) on LPG. The BSEN Standard (if anything) is m...

Re: Cutting out when switching back to petrol !!

If the fuel return was fitted after calibration the system would need to be recalibrated again or fuelling could be very wrong. If it's a Flashlube brand lube system it won't inject lube into the gas feed to injectors, so gummed injectors due to lube flowing through injectors would be unlikely. Is i...

Re: Cutting out when switching back to petrol !!

Wouldn't expect you to get any errors in the diagnostics... But this doesn't mean the system is calibrated properly and it might not be. Check and compare fuel trims between running on gas and running on petrol. Being on a Mustang (Ford) the system may include a physical fuel return, if the nozzle/j...

Re: Regulator pressure decreases when engine gets hot

The injectors in the vid are V37's, not V30's. The tool is effectively just a dial gauge with a bracket to hold injectors. If the car only has sfft's they will still show 0 (or perhaps a number such as 25) when the engine runs in open loop mode. What I was getting at is that fuel trims won't be any ...

Re: wiring problem bigas sgis

Tbh I don't remember if the C systems injector driver (for more than 4 injectors) also functions as a petrol injector cutoff/emulator. Believe there was a brief period during change from C to N systems where N ECUs featured a built in vacuum sensor. But the main point in the difference between C and...

Re: 2006 2litre ford Mondeo constant P0171 code

What codes are you seeing (P0171, P1132, both, others, etc)? And on what fuels (only on LPG, only on petrol, or both)?

Re: Regulator pressure decreases when engine gets hot

Wouldn't normally adjust V30 injectors using an allen key, there's nothing to adjust, the allen slot is there to secure posts to rails. Only a few brands of injectors (mostly now disappeared) are adjustable.. If you had an adjustable type and did tamper with the adjustment the chances are you'd only...

Re: Regulator pressure decreases when engine gets hot

Plenty systems use only a diff pressure sensor but still the reducer output pressure should be relative to manifold pressure, so still the reducer needs to be connected to manifold pressure. Don't have to read far between the lines in my points in my previous post to see why not connecting the reduc...

Re: wiring problem bigas sgis

My system has separate ecu (with built in vacuum port) and driver box, quite old but both multi plugs seem nice and clean. Does the ECU itself have a built in vacuum port or is there an ECU plus a separate pressure sensor with 2 pipes connecting to the pressure sensor? If the ECU itself has a built...

Re: Regulator pressure decreases when engine gets hot

Since the system meters rail temp and diff. pressure it is almost certain that it will compensate for both... But how well is a different matter. Usually provided injectors aren't pushed to the lower limit at which they can accurately dose gas to cylinders (low ginj figures) default temp correction ...

Re: Diy fitting?

It is easy to refurb injectors but a refurbed injector isn't a new one and for the difference in cost between new and refurb kit (and time spent refurbing - and in some cases potential to mess up the refurb) might as well buy new imho. Don't mess with the reducer unless it's broke. If there's no gas...

Re: LPG installer

The BRC ECU and it's loom removed from the 6 cylinder engine are unlikely to be compatible with an 8 cylinder setup. Especially if you're after a tidy install on the V8 A8 BRC wouldn't be a great idea anyway. The port injected Audi V8s can be converted, I've done a lot of them with excellent results...

Re: Diy fitting?

Wouldn't it be quite a coincidence that LPG wiring has recently been done using Scotchlocks and now there's a none start situation and the petrol ECU reports failed cam / crank sensors? What did the car run like before any LPG install work was started? If it ran OK I suggest you've messed wiring up,...

Re: 2002 l322 coolant hose probs

Lovello is one type of sensor, yes. You check it's working electronically correctly using the screwdriver method and a multimeter as others have suggested. For Prins I believe you need it's electrical spec to be (roughly) 10>90Ohms rising. Edit - post crossed with Gilberts, haven't checked yet but I...

A 4 hole tank has 2 floats, a dedicated one for the gauge in one of the 4 holes and a dedicated one on the fill port for the 80% fill limiter in another of the 4 holes. The other 2 holes are the gas outlet solenoid (or outlet tap with excess flow prevention valve on a forklift type install) and the ...

Re: Unknown make (cogas Lambda 2000s)

A lot of stuff not commonly seen in the UK / made in the East is a loose copy of more usual stuff or at least borrows from the design. The bottom half of the reducer looks very BRC like. If it does have a petrol shutoff solenoid (on a fuel injected P38) it shouldn't have really, it should cut the pe...

Some mixer / stepper motor controller ECU's are set up by just watching LEDs on the unit itself and setting dip switches or using a plug in tool/electronics (instead of a laptop) to make adjustments...

Re: 2002 l322 coolant hose probs

7 and 2 seem to be correct. The diagram is arguably more confusing to look at than the setup itself, when you look at the engine it's obvious which 2 pipes run directly to it. It doesn't really matter which way the water runs if the reducer is mounted low enough and it's bled up but there are ways o...
