Hello dear people, I spoke today on EMS with a well-known tuner, and he said the following about the N75J: “Take this out immediately!!!! Two of my customers had already melted pistons.You only need to go on the track once and drive up to the road and already bangts” My opinion looks like this: – first of all, his customers had already revised machines – second, I have been on the road with the valve for 3,000 km, of which a total of about 60 to 70 km with vmax and determined 1000 km with approx.160 to 200 km/h. – thirdly, I think that some tuners try to talk the cheap n75j bad to not endanger their significantly more expensive chips.To the first point he said that it would be no matter whether original or tuned machine, because the control unit is cheated by 0.15 bar and thus the mixture is thinned, the combustion temperatures rise accordingly rapidly. In order to eliminate stress peaks, 0.15 bar of course come to much more (see emaciation by defective lmm – same result). to my already driven track with vmax he said that I might have been lucky in winter, but in summer the machine would definitely go up. moreover, the surrounding air pressure might have been at my best by chance. the last point (for example, chips can also be sold in Wieterhin) I preferred to keep to myself because he was very convinced of his opinion.What do you think about it?
