Re: Misfire after a service

Or maybe it isn't different plugs / gaps that's caused the problem at all... maybe they accidentally/unknowingly did something to the LPG system while changing the plugs. Your best bet regards plugs would have been to refit the same make and model plugs (iridium after all) that were removed. Don't o...

Re: BRC sequent 24 MY07 flashing light on dash button

If it does idle on petrol it's unlikely you've gone far wrong with wiring. BRC switches can flash if the signal they're getting from the fuel level sensor is out of range but that doesn't cause effect anything besides the level gauge. Expect mapping to involve a bit more than just the aided procedur...

Re: OMVL P1003 - Reducer Solenoid Valve

If you get a system rich code that causes open loop fuelling, the graph you made could be a bit meaningless if the point where it seems to go rich is after it's gone open loop. It works on LPG, so the LPG code for solenoid coil errors etc won't be having an effect or causing your problems. No pics o...

Re: Renault Clio 2003 misfire on LPG after getting warm from idling.

It gets warm as the engine warms.. but I was asking when the problem occurs has the reducer gone cold again? You would have to check this immediately when the problem has just occurred as the reducer can very quickly warm up again.

Re: DTgas Injector hunt

Electronics would be the LPG ECU, it's loom, pressure sensor, interior fuel switch and possibly (depending on what ECU you replace it with) but unlikely the reducer temperature sensor, less likely still the gas vapour temp sensor (because most modern ECUs use a pressure sensor that has a built in ga...

Re: DTgas Injector hunt

That is an unusual injector. Done a bit of research, seems the interface will be the most common bog standard Molex type. In which case most of the common cables (Stag / AEB etc with a Molex end) should work. Obviously can only be true if your ECU has a Molex connector. It is likely that the install...

Re: BRC Sequent 32 LPG Issues ...

It has always been wrong because it comprises parts that are incapable (mostly ECU and mostly but not entirely due to firmware) of giving good results on your engine. But glad that you found the reason for this latest and worse problem! Little point in doing a training course - blind leading the bli...

Re: OMVL P1003 - Reducer Solenoid Valve

Difficult to make out in the pic - does the reducer have 1 or 2 vacuum pipes going to it? If 1 it's probably an early new type Dream reducer (the ones that won't flow as much as the old type) and could even have been swapped once since the original install already, if 2 it'll be a type that was only...

Found the problem. The injector sequence was in opposite direction. Now, its running fine. :P
That's a routing problem then ;-)

Your map will still be wrong though unless you've changed it a lot since the pics.

Re: OMVL P1003 - Reducer Solenoid Valve

If you look in the Parameters section of software you will see the reference/reducer/pressure setting. Usually if this is set at around 0.9 bar you'd need an SP reducer, 1.2/1.3 bar need an MP reducer and 1.6/1.7 bar need an HP reducer. However, the numbers in your map are high which (presuming your...

Re: Renault Clio 2003 misfire on LPG after getting warm from idling.

Doubt it will be any of the things you mention but there are plenty of other things it could be. You're sure the reducer stays hot enough when the car is parked up and idling? Worth checking if you haven't already checked, it's contrary to what you're thinking but is a check worth doing.. The proble...

Re: New member but long time reader

Welcome Mick. Could point you towards sorting the downhill Mil issue and possibly switching back to petrol over 6000rpm. A lot of Stag systems are setup by default to switch back to petrol after 6000rpm, you can change that in software easily but then watch pressure, gas injector pulse lengths and m...

Re: BRC Sequent 32 LPG Issues ...

Is it any lumpier specifically during fuel changeover than it was before (we know it's lumpier overal, but in relevant terms)? And, if so, have you moved injector plugs? What I'm getting at is that such symptoms could be due to incorrect input channel / output channel routing.

Re: BRC Sequent 32 LPG Issues ...

There's usually a way of confirming before buying new coil packs... swap positions and see if misfire codes move with coil packs... but no easy way of confirming coil failure before swapping positions.

What did you change in calibration?

Re: Tartarini SGI has stopped working.

By all means move the vacuum pipe connections to facilitate reading manifold pressure via the LPG system but remember to put piping back to how it was before running on gas again or could expect it to throw calibration way off. Reported cam sensor errors often turn out to be phantom errors on these ...

Re: OMVL P1003 - Reducer Solenoid Valve

Same issue on petrol... So unlikely to be an LPG issue. As I'm sure you know, the LPG system takes it's primary input (petrol injector pulse duration) from the petrol system... which means that most petrol system issues (sensors / vacuum leaks / etc) will be reflected when running on LPG. With the s...

Re: lpg feed pipe size on 500 bhp engine.

Great stuff Rob! Know what you mean about not getting much vacuum at low rpm with individual tb's and think I mentioned earlier in thread I thought this could be a problem for calibration 'resolution' (for want of a better term) especially at low rpms. I nearly asked in my last post if there was a '...
