I'm wondering if there is some interference from it... Cut it at the relay and seal the ends. this will rule it out completely for any complications.
I know nothing about LPG installations, but does your flip flop box have any additional functions apart from shutting down the petrol ECU that maybe you are unaware of?The power has been cut, it's not plugged into the old ECU, the worst i can see happening is the engine would cut out if it failed.
It disappears off into the loom so would be a nightmare to unpick. At least while it's in place is keeping connections dry and isolated.
I did think about removing it at the time but thought better of it
This is a good point kermy. The relay could be damaged or corroded, voltage transfer also....I know nothing about LPG installations, but does your flip flop box have any additional functions apart from shutting down the petrol ECU that maybe you are unaware of?
No i did open it up to look, I'm no expert but it looks like it just cuts power to the petrol injectors, rather than cutting the pulse from the ecuI know nothing about LPG installations, but does your flip flop box have any additional functions apart from shutting down the petrol ECU that maybe you are unaware of?
So is it a closed circuit or open?No i did open it up to look, I'm no expert but it looks like it just cuts power to the petrol injectors, rather than cutting the pulse from the ecu
I think you need to ascertain exactly what it does.No i did open it up to look, I'm no expert but it looks like it just cuts power to the petrol injectors, rather than cutting the pulse from the ecu
I ran for a while with the old LPG bits unplugged and it ran fine on petrol.This is a good point kermy. The relay could be damaged or corroded, voltage transfer also....
Have the problems just occurred or have they been apparent from the start?
A simple thing is to go over the whole thing physically and tick it off as you goI ran for a while with the old LPG bits unplugged and it ran fine on petrol.
The new LPG gas always been various levels of wrong so I'm sure it's a setup thing the more i think about it and the more you ask me questions about it
So is it a closed circuit or open?
If you disconnect the relay and do a continuity test on those terminals(on the relay) , it will tell you if it should connected together or not..
I will have another lookI think you need to ascertain exactly what it does.
That's all you can do kermy. The answer is on the car somewhere our mateI will have another look
I bought it a present for the new year. Rear wiper motor arriving this coming week!! Maybe that will appease the green oval goddessThat's all you can do kermy. The answer is on the car somewhere our mate
I likes questions, it's either something you haven't thought of, or makes you rethinkThank you for putting up with the questions
All the more reason to get rid!!Cogs are grinding slowly, if i think back, it's one of these emulator jobs (not the exact one)

When it's powered, it cuts the injectors and send a signal back to the petrol ecu.
When it's not powered, it does nothing
So what is the state of the signal that goes back to the petrol ECU?Cogs are grinding slowly, if i think back, it's one of these emulator jobs (not the exact one)

When it's not powered up it's not sending any signals.So what is the state of the signal that goes back to the petrol ECU?
Hmmm, I wonder if this is more suitable to modern systems and not 20yr ideals?When it's not powered up it's not sending any signals.
The new generation of lpg (which i now have) don't do any emulation which is why the petrol ecu sees real live data when it's actually running on lpg.
This is apparently better, though I'm yet to be convinced.
It has a connection to OBD, so i assume it gets some data that way.Been doing some reading, Although it is not connected to the O2 sensor it does read it. I guess from the petrol ecu signal.
