Temperature and HP

synolimit

Its not the ecu per say, its the tuner. You can pull whatever timing you want based on intake temp. The way its setup though is based on possible experience with knock at higher temps. Instead of pulling timing individually the main timing map can just pull with temps which is real easy. But you could set the timing in stone in the timing/knock maps and set intake temps to all zero. You won't lose power then based off of temps but you'll be driving around in cooler temps with a crappy tune because the timings so low so it works when its cold or hot out. Here's a pic of my WRX. At 85 degrees it pulls zero timing. At 86 degrees it pulls 0.35 and so on.

FYI in the turbo world 1 degree of timing can be about 10hp. So 85 vs 100 we're looking at only 0.35. The power loss is minimal with-in the tune but denser/cooler air can get you a few ponies. At 104 though and -2.11 you're looking at a good 20hp loss.
