Anyone using a wideband lambda sensor?

Saw rob's narrow band one at the show.. very impressive for setup. Was thinking a similar thing using a wideband would be good for setting up

Have 1 plummed into my ECU.

Yes its very good for tunning but bad as its somthing else to worry about when you get funny readings.

Regarding reading the manual I did Twice.

but the Key was in the log file I created and everything was explained just before the high lambda event, while driving I get info all displayed onto a 4 x 20 LCD display thus notioced the lambda reading of 20

Anyway I was trying to say that if you didn't run one you would not know if you were running rich / lean or anythin in between.

IE keeping an eye on

the road, speedo, tacho, water temp, oil presure, oil temp, volts and LAMBDA.

For EFi setup in a closed loop setup- yes very useful. For setting up carbs- its fairly useful. I used the one @ TTS for half-an-hour or so when tuning. If you use it on a rolling road it is possible to keep things (load and rpm) constant and make definitive decisions. Otherwise you just have to drive around and try to remember what readings it's giving under various load and rpm settings (and therefore build a kind of map in your brain).... Which isn't the easiest thing to do when you're also driving, especially as the rpm and load will keep on changing!!!! But it gives you a rough idea of when you're running rich or lean (and its reassuring to make sure its not going too much out of the normal band after needle shimming)...

I have the Innovate gauge.
It will be handy for setting up sva emission maps for my R1 inj with power commander

I've got an Innovate LC1 plugged into my Megasquirt and its been dead easy to use i.e. just connect it up and go through the calibration procedure.

I'm assuming you are using an emerald ECU in which case there is a bit of software written by Chris Good which uses the WB output to suggest changes to your fuel map. I know Neil Everett (nre on here) mapped his Zetec this way - his Mojo build diary is online and has some info and links.
