After checking out that link in the above post, I'm not too sure that those who are posting are very familiar with the VX exhaust system. Who knows though, when you get an O2 sensor thats good let us know how lean burn works with your hollowed out cat...... my situation is still quite different than a hollowed out cat, I have custom little 3" wide straight pipe into a larger than OEM exhaust.
On top of my lean burn hesitation issue I noticed today that my shift light no longer comes on, but the bulb is still good
super annoying, not sure why that would happen. No CEL on.
According to TomO (a moderator on ECO modders), "The upshift indicator (as Honda calls it) reads the MAP sensor, TPS sensor, and rpm signal to determine the best upshift timing."
I wonder if it's possible that my TPS has a bit of a light throttle dead spot, I tried a different MAP sensor and nothing changed.
