What is the Best WideBand O2 Sensor
I'm looking to buy a Wideband Oxygen Sensor to monitor the A/F ratio of my ATI ProCharger with the Aeromotive DFMU. Several times I've gotten a "system too lean" error code and a MIL after an excursion up close to redline. I know it's running rich at idle and low rpm. An wideband A/F should shed some light on whats going on. So, which is the best? I'm leaning toward the PLX M-300 or the AEM, any other possibilities?

I have the PLX M250 as I didn't need the display because I am using it through the e01 and it is very good, at the last dyno it was almost the same reading as the dyno AF.

I have the AEM and would not recommend it. It's nice and compact but the quality just isn't there IMHO.
And it's actually kinda useless to me cause it only goes down to 11. RX-7's usually run fine rich in the 9's.

This is the best unit I have ever seen anyone use. I haven't used it on anything I own, but a guy that lives just north of me has one on his STi. Not sure what the base run was, but with tuning, he gained an impressive 7 whp just by tuning it. Maybe it's not that impressive, but hey, it's 7 ponies just by tuning it. It's good stuff...

i was wondering about this also... i like the AEM because of the guage w/ the digital readout that is great for quick glances... the digitals arent as easy to read quickly... any that incorprates best of both worlds? LEDguage/datalogging?
