EXACTLY!!!!!

The GPS would be nice, but the basic requirement would just be the on-the-fly feedback loop for autotuning.

Greg,

What I'm proposing is that just having the perfect static map for A/F at all RPMs is not enough. Sometimes different A/F ratios at different RPMs in different conditions MIGHT be plausible. That would be the real debate. People may have drastic driving habit differences that could be fine tuned with a "intelligent" mapping system.

In Innovate system has a five channel logging component that could record additional engine temp and throttle position. A marriage between these components and an "end result" monitor such as an accelerometer, could quantify the "seat of your pants" changes that a dyno/tuner would ultimately be after.

The system could try various tweaks during its learning mode and compare the results.

The counter argument of course, is that after the system went through all its trial and error changes, it would simply end up with a A/F based map that would have been available from the start on a dyno. But that's part of the debate. Would it really, or would we be suprised that it developed a slightly different reciepe for fuel mixture that gave more pronounced acceration and handling for each specific driver.

As far as the system being an overwhelming undertaking (PITA); I propose that the latest technology has now put this next generation of mapping within reach. If any reasonable shade-tree mechanic with a few thousand dollars could install a "smart" ECU and just drive around the same streets for a hundred miles or so, and gain the same results a professional tuner could...well wouldn't that be a great aftermarket product?

The hardware is there. Their software spreadsheets already have the necessary data. The missing link is the laptop software to combine the various inputs and then an ECU that allowed RAM changes of the map in real time instead of ROM flashing.
