well the sensor which was changed (before the cat) is with the plug and it was changed after the car broken down, but I think the sensors after the cat are universal (I bought the car with them fitted already - although I know the mechanic unplugged or unsoldered them when checking it).
The LPG system fitted in my car:
controller Stag 300 Premium (but without OBD)
injectors Motogas (I can not find them on the market???)
tank Irene (nearly 2 years old when fitted in the car - I do not know if it's important but Irena's tanks were withdrawn from the polish market just after mine was made)
The car after conversion was loosing power and was burning a lot of fuel. We had to come back to the garage several times where the installer had to adjust the mixture (it was to rich or to poor) but they told me it normal process because 2 people used the car and I do not need to worry.
Everything after the conversion was done under the warranty so I have no invoices (I did not ask to put this in the service book as well - silly me) so installer is lying that I never complained about the system and I broke the car.
Obviously I know that installer should not fit Premium without OBD adaptor (it's against fitting instruction) but I am not sure if it's enough to proof why the car overheated.
I am sure the car broken down before anyone apart the installer looked into the car but the say what they say.
Funny thing is that we tried to find a mechanic who would be able to fix the car - unsuccessfully.
Faults which mechanic stated in my car are
- damage to the engine controller ECU (the engine processor driver work outside the required range, the mechanic told me that Damage to the engine controller ECU in my car have been made by improperly
adjusted LPG installations or improperly its regulations because it is a car with an adaptation of the air-fuel mixture. Erroneous installation or
incorrect adjustment of the installation default setup settings to increase or decrease the injection time, which mean the rich mixture of LPG will reduce the time of injection, lean LPG will lead to increase the injection time.
Injection time can be increased or decreased in this type of motor
controller on the processor until the exceed the ECU/processor counter causing irreversible damage to the software.
IS IT POSSIBLE?
- incorrect pressure compression (burned valves which confirms
- incorrect set the timing chain (variable valve timing) which
according to Nissan service may have been the cause by misfire
- incorrect pressure compression (burned valves which confirms bad mixture)
- burned/melted catalysts
I knew the car was not working properly but every time I went to the installer they knew what to do so car was ok for some time. Last time I ask them to check the installation properly and I did service, they heard the car had misfire but left me with the problem ignoring it. After about 2-3 weeks car "exploded" inside and finally stopped driving without any warning light!!!! how is it possible???
Well 2 mechanics tried to fix it - not successfully - they did engine (I am not sure about the chain) but it did not help.
The one who said it was an ECU change it but it still not working?? A lot of sensors have been changed as well, but nothing.
So I lost hope the car will be ever fixed but I believe the installer ignored my problems and fitted rubbish system - that was the main reason why the car broken down. But I have problem to proof it and also I did not expect they will put it on me :-(
What do you think about that?
