Weather will not change a dyno set to SAE or STD. It recalculates whatever temp you're at and spits out the numbers based on if you were dynoing in 77 degrees or 60 degrees. Only uncorrected will you see the temp diff. Gas on a NA car will do nothing. The chance of knock is very slim with a good tune so you'll see no difference. Lol tire traction on a sub 250tq car is no issue. I've seen traction issues on 1200hp GTRs though. There's no such thing as ecu accommodations. When you tune a car you flash the ecu and dyno. Flash, dyno, flash, dyno. The ecu is set to what its set at. You don't finish a tune and miraculously gain power the next day because the ecu decided to change itself. This is a myth. I've tuned enough and checked power enough day to day to prove this. If anything you lose power. Like when you get a CEL from test pipes after a few miles after a reset. The ecu is continually seeing things are not going right so it richens the mixture then boom, CEL. Now depending on the type of CEL, a hard or soft CEL, the ecu will dump a ton of fuel or just a little. Point is you lost power from it. Once the MAF fuel curve is set, its set. You can drive all day everyday and watch the MAF scale and it will not change. WOT is also not like closed loop within the ecu. WOT is what we're talking about here on a dyno and trust me, once you set it, its set! Your driving around having the ecu "accommodate" for mods is doing nothing for the open loop map settings.
