Fair enough.

Could someone answer me....

If u have may have all these issues... why then BMW gives you the option to update the software of the car? since it can be downloaded from the BMW manufacturer website

nobody knows what the hell you are talking about.

You seem to be confusing tuning (or tunning as you seem to insist) with software updates of some other sort.....

makes me think..... didn't someone mention on another post that if you opt for the m-sport pkg you also have an option to increase hp/tq by from the default by selecting another line item?

i can't remember the option code but i do remember someone mentioning it..

was this just for the X5m or was it also available for 50i w/m-sport?

i have a 2012 50i w/m-sport and this was not available...

obviously i can't confirm at the moment if that's the case then BMW must also be tuning these engines if they're offering an increase in power option...

Yes, BMW have offered tuning options for the V8.

One point is that a complete approach (in the opinion of some of us) to a tune involves new software that keeps all the standard safeties in place, vs fooling various sensors with offsets.

A second point is that if you take more hp out of a given engine, whether by changing rating or duty cycle, it wears faster. That may or may not impact any owner during their ownership period, as they may not reach the wear limit.

yeh or English could be the OPs second language.

tuning or "Ton-ing" as a friend of mine is prone to say, will exasperate issues that the manufacturer knows to exist but that they built to a tolerance not to be exceeded within their warranty parameters.

they built it, they back it for a specified period of time. you mess with it and it breaks you will most likely pay to fix it. if that is how you roll OP............ go for it.

personally ard, i believe an E70 should be flogged early and often. drive it like ya stole it in hopes that it breaks within the warranty period. i have 12K left on my extended warranty and i am shopping for a new transmission. it has started to get a touch clunky recently. if it can be broken, i am the guy to do it. whether i get in under the wire....................... this is not one of my strong points. ;)

so guys what exactly we mean by tunning???? and what is the software update on the car?

Oh....

"Tuning" is when someone changes the factory software in the DME (or DDE for diesels) to change the way fuel, timing, boost, etc is controlled- ideally they 'optimize' this for the very best performance. (Hence "tune"). Often times this removes limits on torque/hp and boost, so you get significantly higher perforamnce. (It is MUCH less effective on normally aspirated cars)

The "software update" on Idrive is for the infotainment system, AFAIK. I am actually unaware of any updates released by BMW for this method.

What's this nonsense ard? The dude asked about "tunning"! ;)
