Not logged the intake temp but what I noticed is when the water temp was lower, the car ran more timing on its own. Initially I thought it was me adding some timing, but something is obviously overriding the timing settings. The tuning timing tables at higher rpm says 26 degrees, but I've seen 28 degrees. Why would it be more? Pretty crazy.

On other software I've used, in particular there are offsets on the fuel for water temps. Guessing Nissan has tables that does the same for timing. Again, just for giggles I changed the Ignition Hi Det tables to see what happens

For right now, being the ECU pretty much does what it wants, think I'll just set the Accessport aside until they make a little more progress. Save my dyno $$ for when the sun is shining so I can actually make a little hay for a change.

Again, very perceptive and excellant post.
