Small victory + Question
« on: January 18, 2004, 12:34:19 pm »
Well,  a small victory today. Ever since I got my 2600 clutch, engagement has been right off the floor. Terrible for shifting quickly!

Finally got off my lazy a## and adjusted it today. What a difference! Well worth having my head shoved against the firewall!

And a question (educated opinions requested):

Looking for some more monitoring equipment for the car. Wide band or EGT guage first? Basically Ive been playing with the fuel lately (using my logger), and would like to monitor changes more better like.

So, what do you think?

wideband :)

there was a good discussion recently over at NABR about this very thing.

Wideband = very cool.

EGT = confusing

Thanks John. I havent been to NABR for a while, but Ill check.

Its a tough call (for me). I would like a wideband to see where I have knock ( in relation to AF Ratio). If knock is low, or non-existent,  EGT's are not nearly as critical.

Ideally, both are a good team.

Yup, you can never have too much info... Who makes a vehicle mountable wideband unit?

FJO apparently makes a good cheap one.

$350 us or so, or so the guys at NABR were sayin

Hey my clutch is right on the floor as well, how do you go abouts and adjust it to make it a little higher up, it kinda sucks.

I'm a little confused here.  Does a wideband replace a narrow-band or do you make a seperate bung for it and run it to the seperate controller?

I'd assume the later just because the ECU might not be able to interpret the signal

the tech. brand sensor and box replaces your stock sensor. it give a full wideband output to your logger and display, and also simulates ( accuratly) the narrowband signal you ecu wants to see.

I would suggest the Techedge DIY kit. Thats what I am planning to get.

It looks like the PLX could replace the narrowband sensor we are currently using at it has a 0-1V output.   (Besides a 0-5V input for logging.)

And cheap too.  I wonder how good the Bosch sensors are.

the widebands we use for tuning and dynoing were a cool $2-3000g's us
thats what proper accurate widebands cost. i dont know if i trust a $300 item

As far as price/quality goes, I know Mike. You get what you pay for. But, what does make the price difference in a PRO quality wideband different then a low price option.

Low price option uses a sensor that does its magic within a certain set of values. Electronics turns that value into something useable. I assume that those values are accurate enough to be valuable.

There has to be more to a $2000 alternative, but what is it?

Well the price difference has a little bit to do with the different and cheaper nature of the Bosch sensor.

At one time wideband sensors were quite rare, but production cars now use widebands for A/F calculations.  Since the narrowband had to be exceedingly accurate at calculating stoich, we can assume that these new cheaper sensors probably are as well.

What will be interesting to find out is how good the temperature compensation and noise immunity of the circuitry is.  I wouldn't be suprised if it is actually quite accurate.
