Woah I didn't say you didn't at any point. The only reason I respect you point of view at times is because you know what you are talking about.
Tuners only do this with the hope of SELLING tuning kits/parts.
Their bread and butter is not the one-off Godzillas, but rather the many many middle of the road mods and tunes they sell for profit. These are the folks who actually do care about some ind of warranty. And in the "old" days, system were less interconnected, but we ar egetting to the point where tuning you engine could void your airbag warranty because of some interdependancy in the system - or that changing taillight lamp resistance could impact the ABS/TC feedback circuit - in which case a problem if discovered could cause the warranty to be voided
|
Thats why Top Secret has a V12 Supra right? Because they realistically think they can market that and make money off of it?
I do agree with you, Tuners do this in hope of developing parts which they can market to consumers and make money. That is the definition of their business. As far as caring for the warranty? 95% of them don't care about the warranty. Only companies that are somehow affiliated with the main brand (dinan with BMW) and a handful thereafter care about the warranty. As you said, the problem is that as systems get more integrated, then the dealer can void more of the warranty by making changes to certain things.
No-one is debating the "harm" that can be done - and harm can be done by changing parameters out of context or range by the way, happens all the time, but we will assume the tuner doesnt do something stupid.
And while removng a speedlimit may seem harmless to you, me and the tuner, if the original programmer intended that value to be used elsewhere it couldimpact something else disastrously.
So - to be clear, unless the tuner actually has the source code, all hacks and reverse engineers are just that, hacks and reverse engineering and hoping for the best at the root level.
|
Harm can be done by changing parameters in the tuning? NO WAY! Harm happens, a lot, because people who dont know how to tune change shit they shouldnt, and people who do know how, push too hard.
Removing the speed limiter could have an impact, no doubt about it. Most likely than not, it doesn't because tuning is very very rarely speed sensitive (unless you start talking about cooling and other dynamic variables, but thats a different subject).
Now, your point is that tuners may change variables which cause other things to malfunction because they don't have the root code? Perhaps.. Thats possible on every car, specially the newer ones. But that is a bit of a self evident argument dont you think? That is true for every car, not just the GT-R.
|
Trust me, us GM guys know all about that - the LSx series of engine management systems are some of the most tunable and editable and changable on the market - and even the guys who have cracked and hacked and sell the software to do so, release updates as they learn new things about the data .
|
Not just LSx series engine management, this is true for other engine management systems that are constantly in development.
Now as to whether "no-one will ever know" - WRONG - everytime you write to these eproms they store checksums and control sequences and the factory knows when things have been reflashed.
Only because they never took it back for something RELATED to the altered software - otherwise the dealer would have to eat unauthorised repair costs And again, a simple reflash doesnt hide the fact it has been flashed.
|
Actually, I'm not wrong. eproms? checksums? control sequences? At least on Subarus, the ECU does not keep track of reflashes, I know this is also true for a lot of other commonly tuned cars.
Is it possible that the GT-R can keep track? of course! Do people who tune GT-R's care ? of course not.
|
This an absurd statement - you are incorrect if you are saying EVERY owner of a GT-R (or any other car for that matter) is going to have no cares about voiding their warranty - now the Mag-Mossy act does protect the consumer from warranty denial for unrelated issues, but even the richest person would rather not spend their own money if they can help it - hence warranties.
|
Where did I say that? I said the ones that tune the car in the first place, don't care about their warranty. Hell, and if they do..they know they cant do shit about it.
|
Wrong again - most of them are confident in the fact that they are only voiding SOME of the warranty as they are protected by the Mag-Mossy act - but would not like to have their entire electronics system warranty voided because they decided to buy a COBB muffler and the tune that went with it.
|
I dont think YOU know what MOST of them think. Neither do I. What I do know is that by touching my ECU I have voided the warranty on the entire motor. No doubts there. However that doesn't affect the rest of my car. I know that changing my springs voids my entire suspension warranty, for sure. So on and so forth.
|
Again, the tuning company makes their money from the mass market kits they sell, not the extreme one offs.
|
Actually, a lot of tuning companies make extreme one offs to show the consumer that they are capable, to get press and to develop the parts that will be marketed to the consumer later on. They develop the products at the same time that they exhibit them.
|
Not every person who mods their Vette, Viper, Porsche or GT-R is going to be a millionaire.
|
Clearly, but every person that mods their vette, viper, Porsche or GT-R is going to be aware, unless they are idiots, that it may just have an effect on their warranty. Therefore most of the non-millionaires will not do it, however the enthusiasts who feel it is worth taking the risk for the rewards, do.
Again with the assumptions - for every 60hp extra 335i's there are 50 more 300hhp extra blown V8s
We know all about "tuning" for extra FI horsepower
|
What assumptions?? I didn't say people don't turbo vettes, all I said was that more power is to be made from tuning for an FI car than a N/A car.
Anyway, the original comment was about the speedlimit being removed, and having Nissan put it back if you went t the dealer (or they may do it remotely even )
Wouldn't it suck if you had your new parts fitted, and the car "flashed" and Nissan set it back to stock and your tuner couldn't unlock it again - because they had patched the eproms 
|
Yeah that would suck, except thats very unlikely. Not to mention that most people who mod their cars dont take it back to the dealership for regular oil changes. I dont trust any dealership to service my car.
Very very unlikely...
