VE Table Load Axis Question

[LSTroll]

Might seem like a strange question but,

Why is it that the VE table for the LS series engines starts at 0 Kpa through to 100 kpa for naturally aspirated engines and all other ECU Software eg. Haltech and Link have their base fuel Maps start at - 100 Kpa and run through to 0 Kpa?

Whilst the HP Tuners table goes past 100 Kpa when forced induction is applied the other manufacturers go from Negative MAP readings to Positive.

Thanks for any feedback.

Cheers

MAP vs. vacuum probably

yep prob just starts at baro 0 and -100kpa absolute vacuum and + numbers for boost, hpt use manifold absolute pressure which is 0 for absolute vacuum and the rest is pressure up to your baro depending on your altitude and above that for boost
