This may have been a issue in the past or maybe it was a faulty unit. Who knows, you cant let a bad experience from years ago stop you from buying the best.
Otherwise we would not be driving skylines because Datsuns are rusty pieces of crap.
Sell it and buy a WB02, you wont regret it!
My sensor is 13 months old, and has been in my car permanantly for this time as well as being removed weekly to tune other peoples cars or check the afr's. at least 25,000km's
I have had my sensor connected while being on 4 or 5 different dyno's and have checked the AFR's. If anything my sensor is faster then all the dyno's i have seen.
And whoever said it had unessasry lag, how the hell would you know if you have not compared it to other systems yourself ? I am one to never listen to what anyone says about something or be skeptical untill i see it for myself.
I can assure you all the wb02 is great, i just got a call from peter, he picked up that my unit had the wrong firmware, he fixed it for me and confirmed my cable is faulty. He is going to fix everything up and send it back to me the SAME day as recieving it.
Id love to see any innovate product get that kind of support. Looks like now il be able to do the road tune on the 180sx on the weekend if australia post get it back to me on time!
