Thank you Tracy, I'll look into extremespark and see if they have anything I can use on my Altima.
Latest experiment last night was removing my hardwired connection to my vehicle sensors. Relinquishing control back to the car wasn't my first idea, but after rethinking and re-reading the manuals that Ron put together I figured it couldn't hurt to give the computer a try at working with the groove.
I'll be doing some longer test runs over the weekend, but so far the vehicle is running smoother and settled down in about 5 minutes after resetting the computer.
Getting gains like this is supposed to be hard, i'm supposed to have to maintain everything and keep a close eye on it so that I can re-tune if I need to. This groove is too easy, its crazy simple and I don't have to do anything but drive this thing. This is crazy, and to think about what i've spent hooking up my vehicles....no i'm not going to think about it.
Thank you to everyone for all of your assistance, i'll be posting some new mpg numbers when I get them after the weekend.
