Ok... So I'm disgruntled a little bit about this topic
Read and decide for yourself... Plenty of threads on this forum and others

NGK is going to be the best and the most accurate budget wideband for tuning


Once again... Learn to use the search button and read

We just bought a ECM AFM1500 unit as I am sick and tired of using the budget crap that is on the market. This setup is not for the weak pocket but considering that ALL of the calibrating is based upon an accurate lamba reading, how can you afford to have errors with equipment.

This unit has a stable 0-5 volt analog as well as serial wide band output. Our new dyno will read serial WB as well as some of our other tuning sofware we use. We opted for the external gauge as well for our dyno cell.

These are the same guys that supply GM/Ford with there dyno lab equipment. So far we are very happy and don't have to wonder if the readings are good when tuning.
