    Agreed, especially 2mm.

    That's what I wanted to know. It isn't a super critical measurement then, cool.

    In the grand scheme of things, IEA tuning is not super critical. This isn't to say that nice things can't happen when done right. Getting the VE% Table right and the timing right is important. Adding a basic -90° IEA Offset can do nice things for most tunes. Further fidling around and building a table using Allan's spreadsheet can get another level of refinement. All of these IEA changes are cumulatively adding 1-2% overall. Boil that down to one variable (injector placement) for a parameter (IEA) that uses many variables, and you start to see how insignificant 2mm (or even 1inch) becomes. Andrew

    Andrew, I made the changes and now the MAP kPa is 98 and the BARO is ~102 kPa; is that what you wanted to see? Also, can someone make some recommendations on the IEA, or do I need to turn it off, drive around for a while then come back to this thread?

    It's not uncommon for the MAP reading with the engine off to be a few kPa off from the Baro. This is what the Sensor Offset is intended for. Andrew
