Re: lpg feed pipe size on 500 bhp engine.

The Prins filter is usually 16 to 12mm anyway... But depending on how it's piped up and what reducer(s) is/are used there might still be the need to get from 16mm to 12mm pipe... Inline adaptors are available to get from just about any pipe to any pipe. Rob if I understand you correctly your MS has ...

Re: lpg feed pipe size on 500 bhp engine.

Sorry the slow replies, so much work on. Really would be best to use same injectors on both engines, likely a bad idea to mix and match especially on the same engine / cylinder bank. Injectors work best when the plunger is pulled straight down, not too bad being horizontal but would never fit them u...

Re: lpg feed pipe size on 500 bhp engine.

here's a log of a couple of power runs Simon , you can see the blue line is the map signal , it shows full throttle then it drops as i close the throttle at the end of the run .. As expected and that is a good sign. For most of the chart the blue line shows near no vacuum (flat out) and you lift at...

Re: lpg feed pipe size on 500 bhp engine.

The inlet trumpets are longer than I remembered them! Know what you mean, I've used T'd vac stubs on engines with effectively similar short inlet tracts such as BMW M5's, vac signal wasn't as progressive/indicative of engine load for a given rpm and throttle position combination as it would have bee...

Re: lpg feed pipe size on 500 bhp engine.

right... now i need to work out how to inject the two engines with a ms2 ecu..... I think you'd struggle using just one MS2, especially since the 2 engines have different capacities so for a given throttle opening they'll be gulping different amounts of air. I'm not that clued on MS2 but even if yo...

Re: Hesitation on moving off

Did you just fit the MJ reducer or fit it, adjust pressure and check calibration? Codes refer to pre and post cat lambda probe issues (readings) on bank 1, multiple cylinder misfires and misfires on cylinders 5 and 6. So most of these codes point to bank1 fuelling except for the odd misfire codes......

Re: 2001 BMW E38 728i OMVL DREAM XXI LPG WONT ENGAGE

First guess from what you''ve said... Your reducer temp sensor is faulty (common problem on these reducers), thus causing it not even to attempt to switch to gas as it constantly reads -40c reducer temp. Plus your reducer solenoid is broken, either gummed/seized shut or a broken coil. It may be poss...

Re: Converting a Ford Triton 6.8 litre 362HP V10 to run on LPG.

A lot of big engine'd RV's I've worked on had stickers under the bonnet with words to the effect 'this engine should not be removed and installed in a vehicle that weighs under X pounds', I think they were from California.

Re: Converting a Ford Triton 6.8 litre 362HP V10 to run on LPG.

A lot of people that import them fiddle the weight figure to below 6 tonnes so it can be driven on a car license.. Why? As long as the driver passed his driving test pre-97, then he can drive up to 7.5 tonnes Gross Vehicle Weight (or MAM as they now refer to it) along with a trailer of up to 750 kg...

Re: turbo astra new problem oi vey ..

Car started on 2 injectors that were not clicking?

Are the injectors earthed whenever they are plugged to the MS? If so is there a wiring fault or is the MS earthing them - easy test would be disconnect the MS ECU from earth and see if the injectors are still earthed.

Re: Converting a Ford Triton 6.8 litre 362HP V10 to run on LPG.

Ideally you need an OBD scan tool to see whether the engine needs a fuel return, if there is a reading for fuel rail pressure then you do need to fit a fuel return. Or you can check around the engine to see if an electronic fuel pressure sensor is fitted, if one is fitted you need to fit a fuel retu...

Re: Ford Transit Mk7 Landirenzo/Omegas problem

Bit inconclusive but pressure seems to respond as it should in the first vid, doesn't seem to respond as it should in the second vid. Since you're not changing any parts besides the ECU's and since it's far more likely that gas pressure minus manifold pressure is closer to 1 bar than 2 bar it seems ...

Re: turbo astra new problem oi vey ..

Seems you need to stop the 'purging' as a first step, this implies the reducer will be flowing a lot of gas, which will cool it, severe cold will cause high pressure even if the reducer isn't otherwise broken in some way. But maybe the reducer is now broken due to previous cold (e.g possible split d...

Re: turbo astra new problem oi vey ..

No injector damage just from the pressure but working them in extreme cold can damage them. Yes you can clamp off the feed to the stuck open injector to run the engine on 3 cylinders while monitoring pressure. May of course be difficult to get a good idea of what the 3 injectors are doing while the ...

Re: turbo astra single point project(now megasquirt multipoint)

Very likely that at least the 2nd reducer froze up due to the leak, outputs liquid gas instead of vapour due to the cold, cold liquid then soon evaporates in vapour lines thus the 50psi reading. Maybe the first reducer also froze due to a leak, in which case it would be the leak that's the source of...

Re: Hesitation on moving off

As Bri said. Plus you didn't mention what car the LPG system was installed on before, you may need different injector nozzles and/or different working pressure to the last car. Or if you made a mistake with wiring / connecting correct plugs to respective LPG injectors you may have it injecting LPG t...

Re: Ford Transit Mk7 Landirenzo/Omegas problem

Not 100% sure if these ECU's only read pinj from channel 1 but I think that is extremely likely. Still, if it runs OK on petrol I wouldn't think there could be much wrong with the petrol injector break wiring. There is an easy way to test if it only reads pinj from channel 1 - just disconnect the LP...
