EDIT : This result should be considered suspect because I used the IAT resistor mod (

Hello -
NEW personal best today on the way home from work. Here's the info :
MPG :
49.0 (old best was 48.1, so a 1.8% increase)
Route : 105 East -> 710 North -> 10 East -> exit freeway -> North on Rosemead
Miles : 36.4
MPH Avg : 43
MPH Max : 70
Net Elevation change : ~788 feet up (+210 on freeway, +578 on streets)
Weather : 65.5+ degrees F, Clear, 73% Humidity, 56.5 degrees F Dew Point
Time : ~9:22 PM to ~10:10 PM, ~48 minutes
Hypothesis : Traffic was ok, but kind of fast for good MPG. I was at 53.1 MPG when I exited onto Rosemead, and I think that is my best to date. I tried the Saturn IAT resistor mod today. I used a 220 Ohm resistor that reports a steady 200 degrees F IAT to the ECU/PCM. Since we haven't hit hot dry August temperatures yet, the IAT mod could have made the difference. I do not plan to maintain this mod unless I can verify that I am still California emissions compliant.
This is a test of the emergency MPG system. This is only a test.
Another big change is the new tires. Calculations show that it should give me a 0.5 to 0.75 MPG jump, which is within the range of what happened tonight. However, since I went from "end of tread" tires to brand new tires, the jump may be greater than 1 MPG. If yes, then this would make the IAT mod moot.
