I have been leery to step into this thread as it addresses a competitor's product, but we're at a point now where I need to clarify some things.
#1, and this is very important: You did not buy an MSPNP product. MSPNP is a trademark of DIYAutoTune.com. If you didn't buy from DIYAutoTune.com, you didn't get a MSPNP. MSPNP is highly developed, and comes with awesome *no extra charge* support to those who need it. Please don't bash my product that you didn't buy because you're not happy with something else.
You could have purchased a MSPNP or DIYPNP from DIYAutoTune.com, but you didn't. Why not? I mean after all we do support the forum with both financial compensation and tech support. We have 4 people with accounts on this site that post. We have user manuals for our products. We work directly with MS/Extra firmware developers, both of which also have accounts on this site.
Our MSPNP and DIYPNP designs stem from real world R&D, real world on car testing, and real world dyno time. And for the MSPNP product, we wrote a user guide and put it on a cd which is included with the box (the DIYPNP user guide is available online). I've looked at the other so called "PNP" offering--which basically appears to knock off lesser optioned DIYPNP. It looks like no such care was taken with the design and basemapping, and certainly I do not see the documentation.
If you needed an assembled DIYPNP, you could have purchased assembled one from Braineack or Reverant. Probably would have cost a little more, but I think you would have found the hardware and the support to be better.
#2. I'm not sure that your expectations were in line with what you purchased. Any programmable engine management requires a level of knowledge going in. This is true of setting up a rising rate fuel pressure regulator and a BIPES or MSD box as bandaids, or a piggy back interceptor, or a full standalone. As you take more control, you need to know more about what it is you are trying to control. If you plan to tune yourself, you have to first educate yourself on what is you need to do. You have already been linked to tuning guides that explain the theory. The theory remains the same regardless of tuning tool used.
It sounds like you wanted more hand holding than your vendor provides at no charge. Sounds like possibly you may be best served by paying your vendor's extra fee for extra support, or maybe next time use a different vendor. I'm not trying to rub your nose in it, but DIYAutoTune.com products do come with user guides. Others, YMMV.
#3, You have to educate yourself. Matt, Russ, and I (the entire DIYAutoTune.com tech dept) have all taken classes by Chris Macelero. He offers online classes, and it sounds like you likely could benefit from them:
Chris is one of the top tuners in the country, and overall is a friendly and knowledgeable tuner. If you need a guy to break down the most difficult tuning topics into real world language, he's your guy. I bounce questions off him time to time.
Maybe you'd rather read some books? Here are a couple on Amazon that could help you:
#4, Documentation. This has already been addressed in part in the above. I just wanted to comment on your stated displeasure with the TunerStudio documentation. I think you misunderstand its purpose. The TunerStudio user guide is there to educate you on how to use TunerStudio. It is not intended to teach you how to tune a car or tuning theory.
OK, long post. I'm sorry if it's a little rough around the edges, but it took me a long time to write, and now I'm 15 minutes late leaving for an appointment. I hope you take some of this message to heart, and that you start educating yourself on the product you purchased so that you can learn to implement it in the way you need.
