As an update, I've consistently been getting 12-13 mpg on my H2 around town, which I think is pretty good. The fuel gauge says that the tank is half full after using about 12.5 gallons since it was full and says it is 1/4 full after using about 18.5 gallons.
When the tank is full, the DIC says I have a range of 330 miles. thus, after using 16 gallons (i.e. half of the 32-gallon tank), it should obviously say I have a range of 165 miles (330/2), right? Instead, it says I have a range of 120 miles after using 16 gallons.
The only reasonable explanation to me is that the DIC "thinks" I only have a 25 or 26 gallon tank.
Is it possible to reprogram the DIC to believe that I have a 32 gallon tank?
As a side concern, even if it is possible to reprogram the DIC, will it be offended?
For example, will it cut off my oxygen supply and leave me stranded in outer space like HAL did to Major Bowman in "2001: A Space Odyssey" after he questioned HAL's accuracy in assessing the fault in the AE35 unit? Is DIC monitoring my posts on this forum? I don't want to irritate DIC, but I was hoping it could be more accurate. However, I also don't want to end up without oxygen like Major Bowman.
I appreciate any answers you can provide. I've fielded this question to the stealership, but I'm not confident I am going to get an adequate response.
