I think until we have the Street Tuner software in hand, this discussion is probably moot.

We can choose to disagree on Dynos, and G-techs... I think we agree Accelerometers and the real road <> Dynos in a garage. Which is more realistic/accureate, to tune to is probably as good as the springs vs. sway bar holy war. There are a number of things a Dyno cannot emulate, but there are also a number of things an accelerometer cannot reproduce as reliably as a dyno.

I am not claiming to be an instant expert, but unless I am mistaken, Nate didn't have a Dyno and ECUTEK SW until when, April 04? Perhaps he had previous experience with the Subaru maps, but he learned somehow, and hopefully didn't blow something up in the process.

If you make small tweeks you will probably never get out of the range for the knock sensor, and timing retarding systems to save you, especially if you are watching real time guages, and evaluating real time and/or recorded data.

I'm not sure Nate or any other tuner has any more tools than the ones I described. They may have slightly more data that is more closely linked, but I'm not sure how much. EGT is not really instantaneous, so it probably isn't much help on a dyno. Wide band 02 might be nice to be linked, but recognizing a spike and corelating it to the narrow band data from the ECU may be enough. What I'm describing may not be perfect, but people have certianley been tuning NA, and FI cars with fewer tools for years.

And as I said, Dynos, and experince are a great starting place, and I plan to take full advantage of them, but want to be able to take the next step as well monitor what has been done.

P.S. Unless I am mistaken, the Street tuner, just like the normal AccessPort does not write to the ECU EEPROM unless you force it to, so it does not use up any of your "flashes".
