Reset Parameters Autoadattativi Mercedes A140

[cristianbomberos]

Hello to all,

I would like to ask you if someone of us to never reset parameters autoadattativi manually or knows the address of where to intervene with regard to Mercedes A140 ecu VDO classic problem of the flow meter

Thanks a lot to all

if you have problems with the mass air flow sensor ? need to replace it with a new one and not rebuilt.

l autoadattativit? ? in RAM, so volatile, no ? on flash...this changes its parameters as a function of leakage of fuel, intake air uncontrolled and the lambda oxygen sensor signal...so in essence changes the zero ideal of the fuel mixture with the aging and the wear and tear over time...even resettandola after a few km you ripristiner? the status of time as the signal of the mass air flow sensor ? one of the 3 key parameters for determining the relationship of load on the engine, if one of the 3 signals ? missing or insufficient, the value of the load to descend? the minimum value of the sensor that has lost its performance

you can replace the slats resistive maf , if as I think it is a siemens vdo petrol , the parameters autoadattivi ? better to reset it , after you have repaired the maf , you Can do it with the Star, even though after a few miles the ecu by reading the probe autoadatta, but if the maf ? damaged as in these cars happens , practically don't do anything with the diag , you have a small calibrations to be used always with the Star

Thanks for your answers,I just wanted to know if I could reset the values by hand why? I also like faberecu I can change blades alone for? first, once you changed me you dettavo the unit with the Star now? seen me ? damaged I was hoping there was a way to be able to reset the values by hand

[ecutuningpro]

the only thing ? to change blades, and then use the star diagnosis. or tararle with resistance

If you need to use resistors or trimmers to adjust the maf, from experience I have to say that makes you get out you fool , if the slats are a new good quality? , and the whole circuit of the maf, it works , the Lambda ? ok you don't have any problem
to the maximum with the star, you can adjust the minimum and some parameter q. the fuel , made many only one I had to adjust the idle speed with the Star then 100% ok
