E38 second IAT use

[Paoloz]

I know that E38 can manage a second iat (one in the MAF and a second after turbo I just added).

I would need to know which pin should i connect the second and how to use it (I see the possibility in the hptuners to set the values for linearization but no how to use it for example to manage advance correction .....)

Any suggestion welcomed

Thanks

Should only need the one in the intake as that is the one the combustion chamber will most accurately see. There are posts that detail the changes needed to compensate for Intake Manifold located IAT sensor.
