Hi all

I need some help.
(first, sorry for my english :) )

I have an Alfa Romeo 156 2,4 JTD 100kw with an EDC15C
and I want to remove the MAF sensor, and switch off in the hexdump.
Anybody tell me the address where i find the switch ???

this is my original hexdump :)

thx for your help :)

Why you want maf off?
On jtd its not the best idea in terms of power or comsuption

MAF off for jtd is a great idea if EGR is off. On the MAP sensor, everything works fine and accurate.

I dissagree,i comfirm last year on dyno,maf off first run,maf on second run,the second run gave me 12hp more with the same IQ,and the fuel consumption eas better too

MAF serves to limit the smoke by limiting the supply of fuel. So MAP can be configured. And where does the power I do not understand?

No,maf serves too to measure air intake temperature,and this is a important thing,on my car ( jtd 16v) maf off gave me 12 hp minus,and quickly put maf on again

I propose only to clean the air flow, and leave the temperature. And in EDC15C5 and the temperature is not needed.
And the power you have decreased, since the default temperature is (~40'C), with the sensor temperature turned off, which ultimately truncated the boost.
