Hi,
I read the thread but didn't see any model identifier or TIS describing how to get an 'accurate' HSI. Regardless, I've always used the pump calculate for my vehicle data. The indicated is only used for short, A-B-A tests.
FYI, I have an Auto Enginuity scanner which appears to report MAF flow accurately. This means I can with the GPS mouse, calculate true MPG vs mph. Just at +90F temperature, these results would be skewed . . . too optimistic. I'm waiting for cooler weather before retesting.
