Wide Band Oxygen Sensor and Weber Carbs
 

Does it make sense to use one of the wide band oxygen sensors to diagnose a car with Webers.

I am thinking of buying a sensor and test fixture from Innovate Motorsports.

I have a flat spot that I am having trouble eliminating.

Is there a delay in sensing.

Will the test fixture work with the Monty exhaust?

I'd check with www.pmocarb.com they'd know...if they do, post the info here too...

best of luck!

I have been tuning with the Innovative product the last couple of days. It is quite fast, but of course depends on the location of sensor. I would think that a tail pipe sniffer would slow things down a little. To help compensate you could use a higher gear to do the pull and this would narrow down the rpm range. You can tie in upto 5 aux channels including RPM and then record this to compare later. I'm still tuning, but has substantially improved things already, since I was going 11:1 on top end.

Easy to use, reasonably affordable, yet short of a chassis dyno. Then again you can retest it for free each additional time :) on the road or track.

I'm using bung, not the tail pipe sniffer which had been sold out for sometime this winter. Good luck.
