Ok now I begin a little to understand. Then the feedback is also active in openloop? I thought that in these cases the probe was completamemte ignored. But, what would be the advantage to do work for the light csrburazione fixed. Why not let finzionare all with the two complete cycles?

[munro]

for what I know carburation is fixed it can be used on naturally aspirated engine when these mountains of cams particularly pressures that make it difficult to follow the maps the lambda in the ecu for a variety of reasons...on your engine honestly without seeing the file and let us help you by some guru of the ecu petrol I could not tell you for what reason it was done always did..then the probe is in openloop is not ingnorata but the ecu does not rely on the info that transmits to the ecu-for example during an acceleration, but it relies on an internal map, the fact remains, however, that it is still monitored(the probe and the ratio lambda) in the maps of limitation of lambda is that if, for any reason, are exceeded, the ecu activates different strategies and security...

My engine is perfectly original except for the kat that there are, and the terminal sports. I is a doubt. I the second I disconnected it from the ecu. Could this be the problem. That is, even if you disable to be kept connected?

[munro]

try to connect it I don't think that anything happen...

[etneo]

I don't understand if the probe is in the open is considered or not. If the carburetion is done by the map, point by point, why the probe should intervene?

[munro]

the probe does not intervene...the probe and only a sensor that reads the carburzione...su what should be I'm sorry?

[etneo]

I'm sorry I expressed myself badly. Is considered to make the fuel mixture at full load in open loop? From the map you set the lambda target, and by means of the probe is maintained?
