Another qu= estion Steve. When you switched the code for TPS are you using it in blende= d tables where table 2 is Alpha–N, TPS and table 1 is MAP based? Or a= re you running pure Alpha–N? It appears a second MAP sensor can be wi= red in externally and left open to the atmosphere for altitude fuel compens= ation.
