I'm not looking for tips / tricks per se, just interested how folk tune commercially vs how I do my own car through my own research. I know the layout of the MED9 stuff quite well now so understand what I'm seeing 98.7% of the time. Some of the stuff is eye opening, some is interesting.
I totally agree, it's not like you could start a tuning business with the tuning files associated with these definitions. I've looked through them and many of them seem poorly done at best. However, there are some good ones and it's incredibly helpful to have a reference point for which map areas you ought to be looking at.
While I'm on my soap box though. I'm of the opinion that no canned tune is worth the $400-500 that most of these European tuners charge.
A $400-500 tune ought to be one that is custom done to a client's vehicle, modifications and ambient conditions that the car operates in. Your money ought to be buying someone's
time and/or expertise, not just a set of calibrations.
It's actually almost a shame how adaptable Motronic is, as it gives tuners a cover. Like how JHM claims that it's V6 and V8 tunes will adapt to your vehicle, like they somehow devised a means to make a one size fits all tune. Selling ECU 'adaptability' as part of your tune is garbage IMO.
To wit: here is a direct quote from JHM's site "
Why is our tuning the BEST? Our tuning is specifically designed for an aftermarket exhaust. It is not another "cookie cutter" software that will work on a stock car"
Some "professional" files that I have looked through have been a huge disappointment. Lots of trickery and numbing of safety measures involved instead of good tuning.
Wow, strange how I just mentioned the JHM V8 S4 tune.... :p Interesting that they push for any JHM tuned car to have catless downpipes or headers. I wonder if that has anything to do with the massive amounts of timing they added and the dialing back of the factory knock calibrations....
