I never realized that your tachometer, when in forth gear, is parallel with the speedometer. I noticed it on the way back from California this week. I asked my buddy about it and he said that in his '98 DX Hatch it is syncronized in third gear and in his B16 CRX it is syncronized in fifth gear. I though that was pretty cool but you probably already knew about this.

i've noticed that in certain gears your tach has a tendency to meet exactly the same spot as your spedometer, but i wasnt aware that they are synchronized...? maybe for only a small range only...but i dont know...

hmm. I duno about that.

unless I'm reading it wrong.. you're saying if you're in a certain gear, say 3,000 rpm, you're traveling at 30 mph?

I know for a fact that if I redline any of those gears, I'm not traveling 67-70mph. heh.

The 4th gear is your 1:1 gear in a 5-speed. It basically means that the engine is turning once for every turn of the drive shaft. That's why you dyno a car in 4th gear b/c it shows what the actual power is.

That really doesn't explain why it would match on the gauges, but ....

I didn't mean syncronized like that, I meant that on your gauges the match up. For example when you are in forth gear and your tach points straight up, so does the speedometer.
