Hi, Many of TFI members are facing problem of 'poor performance but no ECU error'. After doing lot of observation & homework I have zeroed that FIAT has kept too much margin in parameters of sensors to match with bad fuel quality of India:evilsmile. Some may argue that, then why other diesel engines are running without any problem of low/adulterated Indian fuel quality. The performance of other diesel engines in India is at par because other diesel engine can't give huge power & torque like MJD. . I mean 1.3 MJD is the India's most powerful & most torquy engine in 1000-1400 c.c.engine. Engines with more output I mean more powerful & with more torque need genuine fuel quality. Engines with less output doesn't bother about fuel quality. FIAT has mentioned somewhere that they have tuned MJD to match Indian fuel quality.This type of R & D & so called matching is become headache for hardcore fans of FIAT Cars. Please don't misunderstand. This is discussion not bashing on FIAT India & famous award winning MJD.
