Some people do the strangest things...some knowingly, many unknowingly.

I seen a map from a Link ecu a few years ago done by a local tuner that looked like the grand canyon. It seems they had 4D tables implemented so whilst main table was MAP vs RPM, in the background there was also a TPS vs RPM table active and TBH I don't think they were even aware of this, because the grand canyon with the main table seemed to be trying to compensate for what the TPS vs RPM table was doing.

The vehicle did drive, but overall it was a mess.

When using MAP vs RPM as main load, it makes no sense at all to also run MAP compensations.

You can map vs load and manifold compensations, very easier for mapping
Set map up to 100 kpa and use compensation table for boost

That's interesting, but why would you be increasing ignition advance with boost, just seems counter intuitive. But I guess if that's what the engine likes

Yes they should be negative, that;s just an example ;)
