Default Coolant/Air Corrections - Fuel/Ign

Just wanted to post this up here and see if I can get any feedback. All four temp based corrections. What do you think? Any areas that I should tweak to be on the safe side of things? The car runs/drives fine but for the hell of it...

Looks pretty good. If you're using VE tuning, the Haltech does a background air temp v. fuel correction. By enabling the check box and manipulating that map, you're working in addition to that background map. I would disable that particular map all together and allow the ECU to work it's own magic. If you're using injection time tuning, you'll need to enable the air temp v. fuel map and use it.

Everything else looks pretty good. I'd probably throw a couple degrees timing into the low load/cold air temp areas. That's where you'll need the timing when it gets cold out.

I am tuning VE. Is that in the main setup? So under advanced, un-check the airtemp/fuel correction? I only idle at about -6PSI. So add a degree in the -8.7/-26 box?

Yes. Got to Main Setup > Advanced and un-check the fuel/air temp correction box.

Why such low vacuum?

I'd probably do about 3 degrees in the -26 line in the vacuum areas. Do you really drive the car when it's that cold? And 2-3 degrees in the 31 degree line in the vacuum areas. Linearize that down as boost builds.

Big cams and big intake/exst ports in the head (ported head). I don't drive in anything colder than 5* C.
