Hello all, in the workshop I have a Fiat Stilo Abarth gearbox selespeed,the problem ? from cold the car starts, adjust for about 5 seconds, then begins to flood and go out. If the put in motion immediately starts to adjust, and again after 5 seconds and repeats the usual tram tram, after about 4 or 5 attempts so well? the machine tends to stay in motion by one in an irregular manner with detonation, and the catalyst becomes red hot, the gasoline is not burned.If I keep it accelerated until 3000 rpm or more? the car goes well, when ? hot the machine ? perfect. In the engine control unit there are no errors, I tried to replace the following parts: probes landa, bulb ntc, dibimetro, spark plugs, a coil. I also cleaned the throttle body, tested the pressure in the injectors rail ? of 3.5 bar, the injectors are clean,and not well, controlled the stage. I don't know pi? what him, do you have any idea? Thanks in advance to anyone who wants to help me. Good day

the phase've checked with the comparator + gear lock cam right??
however, you can try to unplug the connector that controls the solenoid of the variable valve timing so as not to get it in a function and try...

I rather misurerei the compression, according to me has valves that do not close well.

You step I made with the cappeli and the comparator, the prover? also, to remove the command from the variable speed drive phase

but if the valves do not close well, it should start evil instead of good, if when you turn off the power back up immediately,the machine starts again adjust for 5 seconds, then the problem repeats

Cold, they tend to close better, and anyway, the probe has not had the time to detect the unburnt fuel that ends up in the drain.

? been touched the ecu? It's only cold from the problem? Hot is better, or okay? Excuse all these questions.

when put in motion, keep the diagnosis attacked and monitors multiple parameters possible, something you must unpack, must go out of range for grease.

compression ? 13 on 4 cylinders and 11 to 1

I don't know if the ecu has been touched,the problem ? only cold to hot ? perfect


on the car c'? a gas, or lpg?
si c'? an lpg system sequential, but I also tried to unplug it but nothing changes

I made a video with the following parameters:

If you have a temperature so high at the exhaust ? likely that the machine is a lot of delayed ignition.

I do not understand in the video what happens, you turn off the machine every few seconds? because you fall the turns and the gauge, air will continue to measure the same.

are you sure that in the activations are not there to be the voice of the parameters autoadattativi?

I made a gas plant on a stylus identical and calibrate them before I used that option.

when you turn off is held in the memory of the last parameter in bed before turning off.

the shut down ? the defect of which he complains, but he doesn't know the cause

the problem lies in the lpg mode. but there are failures.
apparently I have not been blocked, the autoadattativi.
remedy: run the car for a few days only to gasoline, the problem will resolve? alone without any intervention.
suggest to the customer to switch from lpg mode to petrol.

your solution ? a remedy that may only work if the ecu gasoline has moved 2-3 points too much towards the skinny but if ? planted to its maximum limit of movement of the zero ideal in the pi? of the time does not work.
if the ecu ? planted on the skinny, there are two ways : turn the gas setting the ecu very lean cos? to induce the ecu petrol to move the default to the rich or reset the autoadattativit? (this is the parameter that is not allowed? be disabled, why? part of a strategy very complex).
if the problem ? persistent ? definitely better to do a reset of the parameters autoadattativi and then adjust the gas ecu on the road in all the possible conditions to follow with a diagnostic tester (aeb ? is great for this) to move in order to make the correction in the right way, if you are not doing this operation you will return? soon at this point.
the operation of adjustment on the road ? one thing that few do why? they say that you lose time and simply load the files on the gas ecu by doing the necessary.

to try to remedy this by introducing the opposite problem (setting gas lean) does not seem a good idea.
then not ? said that the ecu has been tampered with. we start from the assumption that it is original.
when I do a good adjustment on the road of methane, the problem does not exit, why? ? a matter of chemistry, not of mappings.
for these units the remedy ? the block of the adaptations.
or the natural reset of adjustments by the periodic use gasoline.
definitely effective to reset the adaptations, but if you don't "learn" to use the methane in a short time it will be? again with the same problem.

in the gas field, we have sufficient experience of transformation and teaching (21 countries in the world, and technical schools)

I have described the possibilities? to fix the strategy, often I happened to have the ecu planted by ignorant people that set the gas ecu from a standstill, and always tend to be rich, so then with this problem, and I have always resolved as described...I'm not an investigator in this work, I know perfectly how and what to do.

the adjustment must always be carried out on the road regardless of the chemistry or physics that you want to apply pi? load conditions are analyzed and pi? you will have situations different from evaluate to be able to adjust the gas ecu, following the logic of the ecu petrol.

I've never heard of disabling autoadattativit?...but maybe ? why? I don't need...you just need to know what the engine wants and how to understand it that is all simple.

despair can also check the lambda probe: not ? said that gives you the error in diagnosis if it does not work.
tried it on my skin on the 5-cylinder 2.0 turbo

in the first post says that the probe is new, and I think it is just as he says carmageddon is a problem of adaptability that it went out of range.

as a gi? as explained previously pi? times,
you need to reset the ecu,
put in place the gas system in the perfect, and few know how to do it..

if not done this way does not solve the problem....

I do not mean to question your experience.
what do you say ? a shared standard of good conduct in the work setting of the gas.

despite this, the question of chemistry, but it does matter. the stoichiometric ratio of methane ? other than the 18-20% that of gasoline. consequently, the autoadattamenti move of the 18 - 20% compared to the norm.
just that when the ecu sees a shift of 20% starts to give error adaptation, and the light comes on. we are, therefore, at the margin, but ? only a spy.
but for petrol operation when there is 20%, the engine makes the effect described by our partner, who is not claimed.
in addition, the autoadattamenti you can inhibit like any other function. ? the question of how to do that. and this on all units that I know of.
I am (was) an investigator and of course, I have different experience.

we begin to specify that the gpl differs from the gasoline in the stechio to about 5% (to 15.5:1 for lpg and 14.7:1 for gasoline), said this is not ? important to the nature of the fuel used, but bens? that you keep the fuel mixture that the ecu gasoline wants with the same speed? of action that she expects.
so if you car is not put on the road to register the various load situations according to use and adjust accordingly the gas ecu, you will ALWAYS have errors of operation.
the difference in consumption between lpg and petrol ? around 20-25% to the detriment of the gpl, and this varies according to the mixture of lpg at the pump you sell...while the difference of performance in a system with sequential lpg, if well calculated and installed properly, and a maximum of 3% of the above-mentioned engine.

run a reset of the parameters as I have said previously.if and turbo controls the turbine to the cold and the quality? dell.oil.better still if cn examiner to update the sw control unit.solve

given ke you also have a cylinder with less compression pu? easily lead to the outside parameters.if you can see the valve seats and if you have a chance? check compression cold and then hot and do the differences
