Re: plx or zeitronix
Ive said this before in numerous other posts, but here it is again.
I have a Zeitronix WB and it works great. I like the idea of using it with my laptop, its hard enogh to try to read a large screen and drive no less a small digital display. I have been using it for at least a year now and not one single problem has come up with the unit or sensor. It has been run for months every day on my Typhoon running closed loop $59.
Now for my trouble. It outputs voltage that is read in a chart by Tunerpro RT, and correlated to an actual AFR, that TP-RT is running closed loop with. EVERY time I open TP-RT, and do some logging, changing or whatever, my AFR's read different- Zeitronix software vs TP RT. Its usually minor, like less than 1 AFR, but it always happens. When I first installed it, I checked its output voltage with a DVM and it was steady and fine. I really havent spent much time at all trying to figure out why its doing this, but it is. Is it the WB? Is it the wiring? Ground? I dont really know, but I know it isnt right. Trying to tune for lean AFR's at cruise makes this problem bothersome. One day my closed loop cruise AFR will be 16:1 in TP and Z software, then the next it will be 16:1 in TP and 16.6 in Z software.
Other than that, Ive used it on a few carb'd cars with a tach input and a MAP sensor and it logs great by itself.
