So, this post has a few question in it but the main is which wideband gauge i should choose. After lots of research i have chosen between either:

1. Auto meter Cobalt wideband O2 (6178) ~$300
2. AEM wideband O2 (30-4100) ~$170

There is plenty of information out there but nothing that has quite helped me to make a definitive answer as to why one or the other might be better so i would like some others inputs. I know that the autometer has a 4V output while the AEM has a 5V output, not sure if that makes a big difference.

Also, the AEM has started to come out with a new version of this same wideband but with a 4.9 LSU sensor instead of a 4.2 LSU sensor. Claims to have a faster light off time and to draw less current. MAP is currently selling their stock of the old model off first. My other question, if i choose to get the AEM, should i wait til the new one is being sold and is it worth the wait for the advantages (if actually any) of the 4.9 LSU sensor?

Any help is appreciated, ty!

ty for your input but can you elaborate as to why?

You can log with evoscan or accesport if you used for tuning, and do not need free air calibration like innovate.

so do u know if the autometer also has that capability to log for tuning or no? cause i will be using to tune and logging capabilities are important in my selection

I've had the AEM, the Autometer and an Innovate.
AEM is great in that it is easier to log... Autometer uses a 4V range instead of 5V if I remember right... it was a hassle getting it dialed in. AEM took seconds.
Build quality is about the same on them. The AEM feels a tiny bit huskier, but nothing crazy. FYI, if you go with analogs, Autometers are NOISY.

Innovate is a giant steaming pile of dung and should not even be used for packing material.

evoscan and accesport im sure no logging capabilities.

ty superbovine, nice to hear from someone who has used both gauges. do u have any input on the new 4.9 LSU sensor instead of the 4.2 LSU sensor, should i wait for the 4.9 or just buy the 4.2 sooner?

Mines a few years old, so I can't speak on the 4.9 sensor. :/

I use the AEM UEGO wideband.... Its really easy to install also really easy to get working with EvoScan and wire up. I was thinking of swapping over to the new AEM Failsafe gauge but didn't want the tuning headaches of making it work or using there software. So I am pretty happy with the AEM gauge that is what i would go with.

Uego its easier and cheap

Why try to reinvent the wheel

Have to say AEM for a few reasons such as listed above, and if you ever decided to go with a AEM v1 or V2 you could hook the gauge up to your ecu super easy

AEM just came out with a new wideband using the better LSU 4.9 sensor. I would wait for that one to hit the market.

why no zeitronix?

My biggest selling point for the aem I have is accuracy and the price to replace the sensor. From all I understand the most accurate of widebands is the aem and the innovates. But the aem has an off the shelf replacement sensor equivalent. I run leaded race fuel to boost my octane rating so I replace the sensor regularly and the off the shelf Bosch sensor is half the price of the aem version and every bit as accurate. I don't know if the new 4.9 version will have the same ability but if not the cheaper replacement cost is well worth the reduced accuracy of the older version, which in my unprofessional opinion is accurate enough for tuning and monitoring.

Btw part number for the Bosch sensor is 17018
