Alfa mito 155hp

[ducati83]

Hi to all guys I'll post another my question: on the days I got a mito 155 sparkling with brc, practice in the car about 500km the light comes on the engine and gives me as error the values of lambda probes for thinness; I brought the car to the BRC and they told me that most of how to have fattened up they can't do that for them, the issue depends on the wear of the above-mentioned lambda that should be replaced....the customer asserts that he had replaced the assembly of the system and have only 15000km approx.....do you think it would be feasible to delete the probes from the map and try to set the fuel mixture with a stechio and wide band?

watch in the diagnosis, the trim adjustment fuel short-and long-term...of course petrol
these work in a percentage of fuel and tell the ecu to add or delete gasoline to comply with the carburetion in the map...the fuel mixture stft should be at a minimum and at partial loads around the +/ - 5% and the ltft around +/-1%..if it doesn't then you have to start to see first the mass air flow sensor as is if everything is ok it passes control of the entire round tubes, to find any air leaks, even if here and everything's ok, check the fuel pressure it may be that the pressure regulator is gone, and turns a bit lean and then the ecu tries to re-lubricate, but 'the increase in the number is beyond his reach (the trims have a maximum of 25% of the intervention positive and negative)
for the sake of clarity:
stft=short time fuel trim= trim fuel in short period of time
ltft= long time fuel trim= trim fuel to the long period
good luck..

thank you for suggestions....the talk is that the gasoline car goes very well not have the slightest problem....it is only the gas that brings out the error....and I have seen with my own eyes that indeed the map is made by the brc over not able to go....then it creates the error of the parameter lambda in the ecu....
I would like to at this point manage everything manually by removing the probes and see how it behaves in order to understand if it is actually the 155hp does not digest well for gpl....saw that on the 120cv problems with the system in series or post purchase there are....
The brc has been mounted to drive the turbo petrol up to 3500 cubic capacity and up to 6 cylinders so it's not a question of dimensioning of the system....

the fact is that I would like to know if others with the lpg and the engine have had similar problems.

Plants BRC are a good product, the only negative point is that sometimes the injectors are dirty could create these problems! If the gasoline does not have problems the first thing you should check for the press of the gpl that should be about 1.4 bar with the engine running and at idle,then while it is always in motion in the gpl tries to pull iltubicino of depression on the gearbox and see if the lung them to the attack of the tube exits the gas if it is the inner membrane route, finally goes to the injectors, I sometimes them I remove them the food direct intermittently I get them ticking over while the spray with a degreaser brakes,re-mounting them and try it. Of course it would be the case of checking filters, lpg pipework, the injectors that the solenoid valve there is one, and candles.

Here you have to understand if you want to solve the problem or work around with the Dtc off .

Not and which has nozzles for LPG and small?
or tubes that are too long?
pressure of LPG on the gearbox is too low?

I've seen cooked and raw, with plants placed for..

even an Opel Corsa, which is fitted with the swirl had put the nozzle behind the swirl!!
