Got this Dick smith kit for a narrow band AFR meter for $62 AU- I'm thinking that that price + a O2 sensor ($80-120) makes for some fairly cheap tuning to help with a rough tune for forced induction.

Kit KC 5300 down the bottom of this page

The kit is calibrated for a specific Bosch 02 sensorr- it will work on anything, but if you want reasonably accurate results you need to get this specific Bosch Zirconium one.
So I get the kit together & test it & it all looks good- I head to repco for the O2 sensor.......

$531 AUD


Awesome!

So now I need to try and find another sensor with a similar output.....

stoichiometric at 600 mV.

Does anyone have access to source of this type of info????
