Thanks for the update. A quick question (not much time and I don't want to forget): Are you planning any ABA testing? This kind of easily reversed and reinstalled mod is ideal for such testing. Without it, I'm afraid you really can't know if the resistor is helping or hurting because there are just too many other factors, especially given the warming weather. You really need to control other factors to know the effect.

Sorry for the late reply, but yes I do plan on ABA testing. I haven't driven the car the past week because I took a week off from work

I have two full tanks with the resistor in, 43.1 & 43.6 MPG. I will be removing the resistor for this week's commute since the weather will be consistent & the same as the last two tanks.

UPDATE:

looks like the oxygenated fuel is gone and we are officially back to the summer blend!

I took the resistor out the week that the fuel change happened and netted back to back 45 MPG averages, this is with 75 degree ambient & 90-110 degree intake temps ( no resistor )

my next two tanks will be with the resistor installed..

looks like I'm averaging 45MPG @ 65MPH this summer. I have seen a few 50MPG trips but have had to use the A/C a few days on the ride home (black car/black interior = oven). Even with tinted windows it's brutal.

since my last update I have achieved a best of 47.6 mpg for one tank of fuel. I have been averaging about 47 mpg for the past month.

65 mph max, I wonder what 60 mph would net me?
