I'm not sure where I learned it, exactly. Mostly from just talking to other knowledgeable car people. As far as open- and closed-loop - those are terms used to describe different types of control systems. I've had a few classes in analog and digital control systems, so that's where my...

The reason there is more power at partial throttle than full throttle is because of the ECU's fuel delivery system. At WOT, the ECU basically dumps the maximum amount of fuel it can for that particular engine speed. This is called "open loop" operation because it ignores feedback from the O2...

Well, I'm sure that what he's saying is BS. The only thing I can think of is that for any given speed you are ACTUALLY travelling (as opposed to the speed your gauge reads), your wheels are spinning faster because of the smaller diameter (195/60-15 vs. 195/55-15). Therefore, the rotors will be...

Another great tire size calculator to check out: http://www.miata.net/garage/tirecalc.html This one actually gives you a visual representation. Not all that practical, but it's pretty!

ahh yes, the Zener... :D Zener Zener Zener Zener Zener Zener Zener Zener Zener Go ahead, read it out loud - it's funny!

I'm with Bremerton on this. If the Fuel Cut Defenser merely adds an inline resistor to the MAF signal, that would skew ALL the voltages that the ECU receives. Assuming the ECU is continually altering the fuel/timing maps based on the MAF sensor readings, if this signal was altered, you'd...

I agree in that the shifter feels fine for stock, and that the tranny is ultimately the weak link. Think of it however you like - base Protege, old MX-6, etc. The fact is, Mazda did not put very much engineering effort into this component. The RSX-S 6-speed is probably the best transmission...

Re: hmmm Actually, JPBlack was almost correct. The '95-99 turbo Eclipse/Talon used the Garrett T25. The '90-94 turbo DSMs used the 14B. The Mazdaspeed uses a T25R, which has a ball-bearing cartridge instead of the less efficient journal-bearing design used on the old, regular T25. As far...
