Scanmaster W/B Reading stuck on 10.0-HELP!

[jmendlik]

Running the Powerlogger w/TurboTweak 6.0 WB Chip. Issue is this: my scanmaster W/B reading is stuck on 10.0...I have the PLX wideband setup with another digital guage that shows W/B and it's working-just the scanmaster w/b reading is stuck on 10.0 all other scanmaster readings are working..

I also have Julio's alky kit and it's working. If my scanmaster is stiuck on 10.0 then I'm assuming the TT 6.0 built in correction chip is not working?

I did not have this problem before-it just happened today after driving to a local cruise night in this 92* heat.

any suggestions where to start looking?

I have had a similar issue with my LC-1 wideband. Have had it freeze at 14.7 and the little error light blinks. I have been able to get it to go back to normal by just shutting off the car and restarting. I believe TurboDave runs the same wideband as you and sure he will chime in.

Is it stuck only at wot, or is it stuck at 10.0 during regular driving?

If it works as should during normal driving, and pegs at 10.0 at WOT, then more than likely its way rich. If its pegged during regular driving, then sensor is bad/going bad.

Ya, more details. When is it stuck on 10.0? All the time, WOT, idle, key on engine off???

Scanmaster wb reading stuck at 10.0

Let me clarify-

I have the PLX Wideband and also a PLX stand alone Guage as well as the PL and Scan master running on the car.

The Scanmaster w/b reading at idle/drivng around is stuck on 10.0 with 0.0 for KR

My stand alone w/b guage is active and I seeing normal numbers while idle/driving/wot

i have check all wires into the PL analog block and all are tight and making contact-

one thing i did notice is that when i touch the PLX (Aluminum red controller box) it does feel very warm....

anyway-its been very hot here in Chivcagoland area the lastr few days. This issue was on a 95 degree day and the car was running 167* so it was not "hot by no means. I parked it after the cruise nigh and the next morning went to start looking at other causes and I turn the key---W/B on SM is now worlking again!! HMMMM Heat Soak? I'm losty on this one.
