Re: Liquid injection versus gas injection

You're welcome.

There are still a lot of mixer systems and mixer systems are still fitted but there have never been many liquid port injection systems.

Re: Zavoli Alisei momentarily cutting out / switcing to petrol on moderate acceleraton

The amount of LPG that an injector will flow (when fully open) depends on the diameter of the jet in the 'gigler', gas (reducer) pressure and manifold pressure. Since the reducer keeps gas pressure relative to manifold pressure we don't usually need to be too concerned about gas pressure and manifol...

Re: Zavoli Alisei momentarily cutting out / switcing to petrol on moderate acceleraton

When the yellow light flashes while you're running on gas without any beeps from the switch it is because the AEB ECU has noticed that the gas injectors would need to run at (or beyond) full duty cycle to maintain correct mixture according to the calibration map (and compensation for pressure / temp...

Re: Liquid injection versus gas injection

My very rough guess of proportion of the different LPG fuel system types/methodologies of vehicles currently running in the UK, listed roughly in the same order as the system types were introduced to the market... 1. After market mixer systems. This includes mostly older vehicles, mostly fitted more...

Re: Diy fitting?

If it's a silver looking ESGI ECU you can't use a cam or crank sensor, if it's a black looking ESGI ECU you may (but unlikely) be able to use a cam or crank sensor. There aren't many ESGI black systems around. ESGI is a one-off brand (not a clone of anything else) and is one of the most basic ECU's ...

If it's an AEB ECU you can't usually connect the rpm wire to crank or cam sensor.

Re: Diy fitting?

As Bri says it's difficult to see the shape and dimensions / space / angles you have to work in. I reckon a 180degree turn in 8mm Faro needs the parallels to be at least around 5 inches apart to avoid kinking. If Faro is used as fill pipe you can save a little bit of length next to the filler by usi...

Re: S Type fuel leak

You're welcome Howard If the petrol system is tapped into (for the fuel return) in the engine bay it certainly makes sense to fit the petrol solenoid in the engine bay for ease of access and also to prevent having another pressurised petrol pipe running under the car (if the fuel return metering jet...

Re: What fitting for UK Bayonet Pump

The cover on this type of filler is usually part of the plastic back-plate, a thin strip of plastic prevents it getting lost, when not filling it clips to the brass part and to the plastic back plate.

Re: l320 reducer options?

You can sometimes reset learned (and mis-learned) values such as fuel trims by disconnecting a petrol injector, start the engine to provoke injector disconnected OBD codes, turn the engine off, reconnect the injector and clear OBD codes. Petrol injectors on these engines are difficult to access but ...

Re: L320 4.2sc issue

LPGC isn't that location of the reducers incorrect because its not lower than the coolant tank? Yes, it's above the expansion tank level. But I believe has already been mentioned to Themoog on a different thread and it's not unusual to see reducer(s) mounted in this position on Discoveries / RRSpor...

Re: USB interface problem OMVL Dream

At this time there is no evidence to suggest there might be a problem with the LPG ECU.. But the calibration is probably far from correct. I would need the info I asked for in order to advise on LPG calibration - I need to see pinj when the engine is running on petrol and pinj and ginj when the engi...

Re: USB interface problem OMVL Dream

Suppose we have a 4 cylinder engine with firing order 1342... A full group injection system will fire all 4 fuel injectors at the same time. Firing of injectors may be triggered/timed to a crankshaft position sensor, most likely all injectors will fire once per 360degrees of engine rotation in which...

Re: l320 reducer options?

You might try this... Clear OBD codes and then immediately turn the engine off and leave it until the engine has cooled down (even better overnight). Start the engine (run only on petrol since your LPG calibration and/or fuel return are probably bad), don't let the engine idle long, immediately set ...

Re: USB interface problem OMVL Dream

I'd expect Fast labelled coils to be closer to 3Ohms, earlier (none Fast) coils to read maybe 6Ohms. But they're labelled Fast, all read the same and it's very unlikely they all have a problem!
Maybe check your multimeter... what resistance does it read if you just short it's terminals?

Re: USB interface problem OMVL Dream

The Dream reducers sometimes have a sticker on them for SP, MP, HP. Did you say injector coil resistance is 8 Ohms? Should be lower than that.. Measure a few of them using a multimeter directly on the coil electrical pins. May be handy to know what size nozzles are fitted to your injectors. Could yo...

Re: USB interface problem OMVL Dream

No problem. What type of reducer do you have (I'd guess it's an OMVL Dream based on your guess it's a HP version)? I held back from suggesting/agreeing with rebuilding the reducer so far because you've said there are no leaks and because we may yet need to decrease pressure. if it's an OMVL HP it ma...

Re: USB interface problem OMVL Dream

Stick with the OMVL Fast setting for now then, we may later try a different setting. The reason I suggested changing the setting to Matrix is because behind the scenes some software injector settings impose a minimum pulse duration - if the ECU imposes a minimum pulse duration that is longer than th...
