EGR edc16c8 the Alpha and the error p1238 mass air

[matech]

Hello all,

I have a survey to do:

I disabled the controls egr by mapping a total of about 5 edc16c8 of the Alfa group, 1.9 jtdm 140cv

a little run for more than a year without problems
but the last two that I did after a bit of time to generate the error p1238, relative to the mass of air sucked in is too high.
the contorlli EGR have been deleted, eliminating the four "flat maps" on this type of ecu... but I repeat that 2-3 cars go around a lot without this error...

I doubt that the error refers to some other problem, of course, but since all of the literature refers to the problems of the EGR, the workshops, of course, break the boxes to me :-D

unfortunately, the ******* it does not delete the individual dtc on this ecu....

any idea?

PS: also checked all the hoses and the heat exchanger, no loss...

email the file that there is a step to comply with

It had been only one, I would have thought of a problem that is not attributable to the mapping, but in this case.......
Can you post the file ori and mod file of one of the two?

If you do not follow this step, it seems to me that should not be even in motion. However, the poster? the file...

no bitchy egr continues to work

as he told his friend, except you'll want to post the file, maybe you ? missed something

email the file ori, and I am there happened you have to touch the other map! ..also post the mod!

we await your news enlighten us.

Here are the files...

have you tried to reset the map of the swirl?maybe they are the ones that you create problems of air into the manifold and the ecu gives you that error
