Unable To Change Values in Fuel Section

[taguru]

Trying to add injector data and it seems like hptuners is putting in its own figures that are close but not exact. For instance- Short Pulse limit is 3.997 stock. I changed it to 2.500 and after I hit enter it changed to 2.508. In injector Flow Rate vs. KPA under 0 the stock setting is 28.708. I changed it to 37.260 and then after hitting enter it changed to 37.265. I know these are not huge differences but would just like to know if I am doing something wrong or have an incorrect setting somewhere?

That's normal. The calibration has to store numbers as hex, so when you enter a number, it changes it to the nearest hex value available.

Thanks! Just wanted to make sure I wasn't doing something wrong. I hadn't noticed that in the other sections.

This is something that was a lot more common with older computers...almost every number we could manipulate would change to something that could be a hex value.

On these newer ones, a LOT of the data is high enough resolution that you'll rarely ever see this happen, usually you'll only see it in the fuel stuff.
