@KKAUL What I am really not convinced is for remappers blatantly experimenting with engines at the customer's expense. Real time data is available with real time logging tools. But mechanical stress such as the one on lifters, cam lobes, crank, the pistons, rods and such will definitely be affected. And that effect shows not immediately but as you said in overall engine life. That too if one is willing to accept pre-mature failures and willing to investigate deeper. More often than not Fiat will end up getting blamed more by the customer and the gully mechanic. This has some thread to discuss. Although here the remap is a workaround to the gear ratios which too have been discussed in the past, although not at length for sure; but having said that the present gearbox irrespective of the fact that FIAT tunes it for FE and some power and in higher gears does have its limitations, and part of this equation is the engine size as well. I have no doubt in my mind that Fiat could have done a better job for those who drive in traffic. Agreed that the shifting needs an adaptability to how the engine responds to throttle and timing it perfectly as per RPM. But reality is that esp. on Linea MJD, my observation is one needs to consistently be in 3rd even in smaller lanes or by lanes to make it feel effortless a drive. Therefore, in my simple non-engineering logic I try to avoid or rather dislike downshifting to 1st and 2nd. Of course if it comes to it which it does often in traffic scenario here, I shift fast throught the first two gears and you cannot feel the strain of a heavy to haul vehicle feel.
