*********** and the punto jtd 85cv part the second

Hello
a value that I do not understand ? the AIR MASS MEASURED MASS AIR OBJECTIVE.
Here I get the values that are discordant with the type MAM 43 and MAO 230, I go to memory poster? the screen of FES that now I don't have on hand.
With FES on my alfa, the two values coincide with a minimum of waste, instead, here are the values that I do not understand, using a module for mass air flow sensor the value MAM grows to a few units. For the sake of completeness of information values I measured from a standing ... ... .. but also on the ALPHA.

but strange things happen all the time to me, or what?

hello and thank you for your help. Marco.

The measured value indicates that the.mass air flow sensor or ? very dirty or not working properly, see if it is limited to the quantity? fuel injected , it should relative to the map.according to the map of the limitation of the flue gas according to the flow rate read from the demitro

thanks for the reply, I translate the last part of the message, please.

Hello Mark.

The air mass measured read you the map that spian? to close the EGR. Instead of the air mass, the objective was often measured poorly by diagnosis why? there were errors in the map made by Fiat, even on my JTD noted those courses that are ridiculous, yet the machine worked fine, then I updated the SW and magic now from the diagnosis, I read the correct values!

maybe I got it wrong.... but the map that has the car ? ORI.
Who says to my father, who has the EGR closed ... ... and especially those who put it closed ?
throw it on joke why? I understand that I am too beginner to understand.
Thanks.

Hello..do not worry if you notice differences between the measured and the objective...on the first jtd as told by sandro, there were issues of protocol software..., and it marked less air than is actually? he was reading...all normal only a small software bug

[marco147150]

but this is a bug in the software can? be proper remapping , or just mom, fiat f? this type of update.

if you can find the problem and you have time to dedicate to you succerisco compare files of a 156 1,9 115 hw740 sw242,796 in 242 d? your problem, in 796 ? resolved, of course ? an update, and then not ? the only thing to be touched!
