well now that thats been all cleared up. does the blitz supercharger have an electronic clutch? i was reviewing the installation manual and the wiring diagram and it had this thing for an electronic clutch and i'm assuming thats apart of the S/C bcuz our car sure as hell doesnt have an electronic clutch

Agreed on all accounts with largeorangefont. The gauges are an indicator to monitor how your parameters are doing. An EGT meter is very important on FI cars, and i'd like to know your readings on track days, to see how hot this motor gets.
The lights on the dash, when they do on, usually it's too late. All the damage has been done, hence the need for gauges. |

And what would be considered too hot on an EGT guage? Do they typically have a green and red zone?
What would be the remedy?

the remedy is to stop driving.
I'm looking into some aluminum radiators for our cars, I know mine will benefit from running a little cooler under boost.

One item that will be on my car (an Echo, not a Yaris) before it starts competing will be a shift light, but not used as a shift light. It will be hooked up to the oil pressure sensor. By the time an oil pressure gauge drops, and by the time you actually notice it has dropped, it can be and usually is too late. A big ass bright light in your face on the other hand at least gives you a chance of saving your motor.
And for any forced induction car, a knock sensor and gauge. |

PLX Devices
They make a lot of different products. They are popular in the 300ZX and 350Z arenas. If I were to get a wideband Id get on of theirs, AEM or Innovative. |

My WRX could hit 1600 no problem, and my Cobra rarely breaks 1400. Turbo cars can get you into trouble because you can hit full boost at less than full throttle. An example would be going up a hill. If you go part throttle up a hill in a turbo car the boost will rise and you will see EGTs climb. This is where you can cause engine damage. This is precisely why EGT and boost gauges are needed on a turbo car. The solution for this is to let off the gas and not make any boost, or floor it to get the car to the open loop fueling map and bring down the EGTs with extra fuel. Supercharged cars do not have this problem because boost is limited by engine speed. |

Ok, I need a little bit more clarification.
A wideband A/F will read exhaust O2 levels and calculate whether I'm running lean or rich. An EGT will measure my exhaust gas temperature. I already have an O2 sensor in my header. Do I need to have a muffler shop poke two more holes in my exhaust system to put in the A/F and EGT sensors? I am assuming I should put this after the header and before the cat, right?

You actually have a 0-5v A/F sensor in your header, just to be clear.
Yes, you will need another bung for the other sensors you add in that path. I don't think EGT is a critical one, but that's just my opinion. If you're adding a bung for an A/F sensor, it should be as soon after the existing one as possible.

That's what I thought but I figured that the signal only went to the ECU. Can I splice into that set of wires to feed the A/F also?

isnt there two sensors the first one closet to the header was a wideband and the second one after the cat a narrowband

no. the first one is an A/F, the second (between the cats) an O2.

there's narrow band and wide band o2 sensors, they are both a/f sensors narrow band, like nearly all cars have are normally referred as just "o2's" and they either read rich or lean, hence the term narrow band a wide band o2 sensor is comonnly called a "wideband" or "air/fuel sensor" it reads more in depth and allows for more precise tuning of the air fuel ratio.

Can I get a single combo Boost/Vacuum gauge or does it have to be boost only?
Does this mean that the intake manifold pressure will show max vacuum at idle and then swing to low vacuum at WOT (S/C not engaged) to boosted psi if the S/C is spinning? It's been a while since I thought about how an engine functions.
