The ECU can select from various maps based on a lot of conditions. Your previous runs were hindered by the weather or the intake or any of a hundred other variables.

One thing I notice with my obd plug in reader is that timing can be dialed back to negative numbers based on whether or not the ECU can get a intake temp reading or a airflow reading. When the display has a (---) for either of these variables, I can switch the display over to timing and it always is negative. Dialed back timing will always hold your power down to less than what it could be if you restart the car and get all those readings into the ECU.

I doubt it, its 9 degrees here and I dont see that big of a difference

I think below about 40 the difference is small. Humidity is probably a factor too.
But some of us in normally temperate areas like CA, have experienced a huge drop in just a few days. From a daily high of 60 down to the 30's virtually overnight.

ya thats true

its about 45 right now, and I haven't driven my g in like a week. So I took it out today and it felt goooood. throttle was nice and crisp.

Loving the cold air here in NorCal especially with the weather being dry. Lows in the high 20's and highs in the 50's.

You really cannot rely on the Gtech. That thing is so innacurate, it's rediculous you guys spend the money on it.

dont beleive me? record a video at the same time while testing with gtech and then figure out time frame by frame,,results are dead on same on both....

Actualy i have used Gtech for years and found it to be pretty consistant and accurate/.

Temps in KC have ranged from 2 degrees to around 15 degrees. My car sound strained and coarse driving around after being fully warmed up. And like MikeButcher said, when the temps get really low, traction is a problem, even on dry surfaces. It seems once temps drop below 30 or so, spinning the tires from stop, roll, or around a turn is terribly easy.

My G is the same. It runs much better in moderate temps.

cold air does wonders. Too bad we got Ice on the roads so I cant enjoy the wonders.

Here in florida, with the humidity being so high and it always being so hot, when it finally cools down to about 50 degrees with no humidity the car go bat ****.

Agree, it's absolutely consistent. 0 to 60 does not even scratch the surface as to it's full capability. The advances in microelectronics are a given. I picked up the GT2 for $85, less than half the original Escort price. 2 axis accelerometers are not expensive any more, or the integrated electronics to process the information.

Yea I do notice that its very easy to loose traction on the g even running on 225/55/17
Might have to upgrade to a 245 or at least 235 for the rear

This morning (Tuesday Morning), I drove to work and thought it was dew on my windshield. I turned on my wipers and all I heard was "SCRAP": Dang, it was frozen dew on my windshield and rear window. I had to use the WW fluid and then turn it on again for about 5 times and then it went away. Dang, it was cold...brrr...about 40 on my car's Thermostat. Boy, I see why I'm not living in cold weather! What do you guys do to get rid of the frozen dew on the windshield if it is really caked on there? Use a scraper or something?
