Re: USB interface problem OMVL Dream

Very good! I couldn't find my previous notes on AEB2568 pinout, so last week when I had a spare half hour I manually checked a loom and noted the pinout.. From my notes (my notes lol.. so they probably won't make quite as much sense to other people but I'll understand perfectly if/when I read them a...

Re: Newbie question: sudden 30% increase gas consumption Prins system

Most Prins systems don't have a vacuum connection between reducer and manifold but even if it hasn't got a vacuum connection a leaky injector could cause same symptoms. Certainly it would be worth checking the plugs. VR6's can be more difficult to start if fuel trims have been learned incorrectly an...

Re: Time to do some tuning

They look like V34's but metal bodied, they have the Emer logo on the coils but iirc unlike most 34's these have the screw thread on the side. Can you remove them from the car and unscrew just the lowest part of one of the nozzles, take more zoomed out pics from a few angles and measure the hole thr...

Re: Time to do some tuning

Morning... ;-) No, the bar reading moved further towards 'too small' because initially the pressure reading was 1.3 bar but the injectors were actually seeing 1.9 bar, now they're actually seeing 1.3 bar the injector flow rate relative to petrol injector flow rate seems even smaller. We had to conne...

Re: lpg toroidal tank

You should not even fit a tank in the engine bay, at least not unless you make a partition to separate the tank from the engine bay. No tank should be fitted on an incline either, most design tanks have to be fitted horizontally. Tanks that are mounted vertically are specially designed to be mounted...

Re: Time to do some tuning

As it stands your multiplier figures (numbers in the boxes in the map table) will be very high because with the nozzles you have fitted in the injectors and running at 1.3 bar the injectors don't flow enough gas... In your 'display' screenshot above the 'injector nozzle size' bar clearly points to i...

Re: Time to do some tuning

It is very likely you'll have to increase nozzle size though... As things stand you've got a gas pressure reading of 1.2 bar but that's 1.2 bar above atmospheric pressure not manifold pressure, we'd expect the engine to idle with around 0.3 bar of atmospheric pressure (0.7 bar below atmospheric pres...

Re: Time to do some tuning

Looks like it's connected just about directly over the axis of the throttle body shaft, probably a pipe for the evap purge or PCV system, this position probably isn't on the vacuum side of the throttle body and even if it is it will be affected by venturi type effects... No wonder you're not getting...

Re: Shell removing lpg

I filled at Shell Redbeck Wakefield yesterday.

Then went for a drive out and picnic, up the A1, across route 66 (erm A66 lol), entered the Yorkshire Dales from the North end, ate picnic near Tan Moor Inn (highest pub in England) and drove back through the Dales.. So now I need to fill again.

Re: Time to do some tuning

That's right mate. Don't forget that the reducer also needs the vacuum connection. The map sensor and reducer should pick up the vacuum signal from the same place on the plenum, so usually you'd have a vac pipe connected to the plenum with the sensor and reducer both T'd from that single vac pipe. A...

Re: Time to do some tuning

The map sensor usually picks up vacuum signal from a tap in the plenum near the throttle body (vacuum side of throttle body) but you can use an existing vac line, or if there's a mechanical petrol pressure regulator you can T into the vacuum signal for petrol pressure regulator. Different schools of...

Re: Time to do some tuning

Read this whole post before making any adjustments, I've made a summary at the bottom of the post. MAP (manifold absolute pressure) reading is showing a constant 0.98 bar even when engine load is low, meaning either you haven't connected the MAP sensor vacuum port to manifold vacuum or the MAP senso...

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: 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.
