Meassurement of fuel pressure and mixture,what to buy?

[Jonas_R]

Iam getting a new 3" exhoust turbo back.

It has extra plug for wideband sensor / o2 sensor. I am wondering what I should get if I want to meassure the fuel mixture? I would be nice to have a gauge that could show lean / normal / rich mixture.

Also is it possible to meassure the fuel pressure at all times? I mean where would it be smart to do it? By the fuel rail or by them pump or is it a bad idea?

You can buy something like this http://cgi.ebay.co.uk/Innovate-LC-1-...em230088006414

Damn that was expensive
How much worse is it to use a normal O2 sensor instead of a wideband sensor?

Also do you have any suggestion regarding fuel pressure?

Or for a cheaper option, use a standard lambda and rig up a voltmeter - <0.45v=lean 0.45v-0.50v=perfick >0.50v=rich

For fuel pressure, use a transducer in the fuel line (probably just before pressure regulator?) hooked up to a digital readout (see www.turbobits.co.uk) for suitable examples....
