I agree about the same day thing, I was actually budgeting about 3-4 hours for the whole test (11 5.2mile runs, 67.2 miles, with four stops to add acetone and then a short break after each 2.6 miles segment to record data) and as far as wind and temp I would definitely try to do this on a day with fairly consistent weather, and in the afternoon, where the temperature is relatively stable at the top of the daily curve. (also the run is surrounded by temperature stabilizing ponds and trees, and a wind reducing cliff and again the trees)

A little extra pre-segment driving after adding any acetone seems like a good idea, but how much do you think is necessary? (Peakster's test seemed to indicate that very little time was needed)

Yeah, that really complicates things as far as trying prove that acetone does make an change. If the test does initially show improvement in FE, then the final ECU adjustment should just show even better FE, right? (And then merit further long term testing?)

Yeah, but I thought the unknown amount of fuel in the tank, even after "running out", would pose a problem by being a relatively much larger amount in relation to the acetone/fuel being added and unpredictably skew the concentration.

As for the the fuel pump comment... how hard? Like don't do it?
