here we go again!
i am not an auto expert from BBC.
But i do train new engineers joining Bosch in the EDC17 platform. for your kind info the Fiat MJD is one gen older compared to this. its EDC16 genration! i had to study that engine inside out for taking training session on the said engine!!
the Swift ABS unit is Bosch ver5. just for your info
we guys have done the on vehicle testing scorpio here in Bosch.
we were responsible for getting that Mhawk detuned to 120bhp from 140bhp ( read the vehicles suspension - read ride behaiviour! and breaks werent good enough for that kind of power)
yes we have done the complete project on edc16 c8 ECU on the Mahindra Scorpio 2.6 CRDe and yes the new Mhawk EDC16c39 and the yet to be released ingenio ( aka Xylo) EDC17c04 engine management system and you expect me to think that i am not an auto expert???
if i say that i am a novice in engine systems i am pretty sure many over here will say otherwise!!
guys from PSI auto tuning box techs had consulted with me on releasing the Power box for Ingenio!! they are confused since EDC17 is a tad too complicated. its not simple to fool the RPS since the max output from that is 5v instead of 2v in EDC16
leave the indian customers.
i am designated as platform demonstrator for P596 - mercedes benz 3cyl - diesel hybrid using EDC17CP08 ecu and for Toyota/isuzu p597 that is a 1.6l Crdi engine.
any ideas what this means?? we do developement , integration , testing and demonsration on the platform demonstrator demo vehicle. and yes you can do a hell lot in injection patterns in CRDi engines to get power & smooth delivery its the vehicle dynamics that is suspension and chassis set-up which become limiting factors!! we are forced to study all of that so as to make a suitable power output from engine!!
we guys have to do from scratch to vehicle!
and you think i am degrading other brands?? i was talking facts.
i hope you know that the 1.3 MJD has a timimng chain instead of the conventional timing belt( this is a good thing but since chain usually wont break off like timing belts) still it aint good either any ideas why?? over time the links in the Chain become weak though it wont break off it will start getting noisy!!( and also lead to incorrect timing issues but these are taken care by offset diagnosis in EPM module of the ECU! - clever *******s!!) but this is overlooked since its not noticable in the begining!! - i would call them as cheaters! you can call them clever for all i care. the thing with timing belt is that the life for it is 80k kms that is good enough atleast one can change it before that life ends to a new one. and maintain a steay timing performance!( valve opening stuff - this is for info of very novice guys)
in the chain case the life mentioned is 100k miles that is 160000kms ( this is for name sake its supposed to go double of that because obviously the Chain just cannot break since its made of metal and not from rubber as in belt!)
the poor customer he will be helpless since after the long usage say around 60k+ kms onwards the engine will make more noise all the while his engine will be running ok. ( thats what the service guys will say because as per them things are ok!)
he will be stuck with it!!
the timing chain\belt is crucial( dont expect me to answer why . that would be so lame ) in the timing system of the car.
there are more but i am keeping my mouth shut cause i know what are my limits in letting out engine design issues! there are issues with other engines too. but they are on safer side because they go for the lower life- hence replace the component hence the mantra disels are more maintanance its true in this case.
the Fiat MJD was made with one objective to break that myth- a diesel burner can be as maintanance free as the petrol sibling!! they achieved it and the timing chain thingy is just the tip of the ice-berg. on how they went about it.
so please dont think i have to degrade other cars.
i know what i am talking about very well. we guys know from design level when things go wrong in track testing they get back to us for corrections and you expect me to think that i dont know how the vehicle bahaves???
cheers
