What's a good wideband that measures both cylinder banks that anyone her has had good results with?

 

Innovate has the dual set up.

 

Zeitronix Zt-4 -- for Dual O2 only

Zeitronix Zt2 & Zt3 combo for Dual O2 - Plus hard wire monitor/Log just about every other parameter you might want. Particularly useful
on these cars as the Obd port is slow for multiple data streams - so just one or two data streams for the more hard to get stuff (knock, timing, injector etc)

 

Thanks guys
