    The new injector vs battery voltage table is really cool in the new software but I have also had several calls from people who don't read the window that pops up when they open their orginal tune. This table has to either be created from scratch or pasted (file>paste from file) from the ICT folder>Injector Offsets in the COMWP XFI2.0 folder. An important thing to remember is.... what your old injector opening time was before.. it was in the System Configuration>Operational Parameters section. Most people were using 1.0ms, 0.8ms or 1.2ms something like that. The old value was injector opening time at 12v, the the software had a hard coded table you couldn't change behind the scenes running. The new 2.0 software has a table that allows you to change this as a voltage vs injector opening time. Here is the important part.... if you paste the injector opening time data and the value at 12v is lower than what you had before you will have to add the % difference to your VE table to get your tune back to how you had it. This table can be scaled for larger voltages for 16v systems or to fix things like when your fan turns on and all the sudden your car runs lean from the voltage spike.
