I have about 50,000+ miles on my ATX and it shifts into high gear when cold around 45 and between 42-45 when warmed up. I installed the shift kit resistors into mine and it did not effect mpg's but did make it a bit more sporty to drive. The resistors should get real hot, maybe even melt stuff close to them 
The upper resonator should not get you much of a gain by itselt, but it needs to be done.
The biggest single gain I got was the 5.6K ohm resistor in the IAT sensor, that got me about 3mpg. It doesn't work so good in the winter, so you might no see the change now, but do it like your life depends on it. It only cost 99cents and works so well for the ZX2.
If you haven't already, pull the Knock sensor, you won't see much of a gain below 3K rpm, but above that it will run so much harder. For my car it smoothed out the entire power band because it was randomly pulling timing.
Toss your stock muffler if you got the itch. It is quite a restriction. Any strait thru unit will liven things up. I put on a SVTF header and it really added some meat to the bottom of the power band, right were I want it for cruising in traffic. |
I think you've got the exact car as I do. Baby Blue too?
Yeah, I think I'm going to take out the shift kit. I just have the resistor in there alone now, not even getting hot. Perhaps I have the wrong wire? Oh well.
Yeah. My future plans are to pull the AC completely out for weight reduction. A better grill block. Partial under tray. And possibly rear wheel side skirts. I'm hoping that I will pull a 45 mpg without much effort and 50 mpg at least once.
I will eventually try the resistor. Although reading at teamzx2 it seemed that it was a hit or miss for a lot of people.
I've pulled the knock sensor. Didn't notice much. I never top 3k rpms any how.
The car feels a bit louder with the completed keman intake.
Well, replacing the stock muffler would be more money than I think it'd be worth.
