"Have had the zt-4 dual gauge for 3years now . I must say all components of this kit are cheap . I’ve had constantly nothing but problems with this wideband . I have had problems with the o2 wire that hook up to the controller box . Makes the afr reading jump all over the place . Checked with my hptuners to make sure everything was running right ,and it was . Plus you can’t even plug this thing in and have it correspond with hp tuners . For your tuner to look at . Aeroforce gauge make zeitronix look like junk and I’m sorry to say that !! Try giving everything the benefit of the doubt ,but here I am installing a new set of o2 wire to my controller cause somewhere in the wire is messed up .. I have no kinks or sharp bends in my wire . I even suspect their lsu4.9 wideband are a very cheap version aswell ."

"Called them to ask for help with their ethanol analyzer product and whoever answered the phone gave me a nasty attitude. They were not helpful at all. Will not be purchasing their products again or referring them. Quite frankly I’ll return their product and dispute it. Take your business elsewhere."

"Every time I call here they always have the anwers, I rarely have to call, I have 3 of their wide bands in various cars and they have always worked well. Good service and solid products. I really like the products they offer."

"Zeitronix offers very dependable and durable products. All made in the USA. Bought a CanBus ethanol content analyzer to go with a ZT3 CanBus Wide Band. Couldn't be happier. Technical support is top notch if you run in to any Issues at all! Thanks Z!"

"Bought the nDash with the ZR-4 dual wideband so I could display and log AFR as well as some parameters through the OBD-II. I was disappointed with the quality overall but decided to try it. After plugging it in, many of the parameters that other loggers could display were unavailable. Customer support was unable to help me with the issue, so I returned the product. At the end of the day I'm out over $100 for a product that didn't perform as advertised. I should have bought a similar product from a more reputable brand. Don't make the same mistake I did."
