wideband problems with m600

[Puerto_rico_nc]

I have connected the bosch lsu 4.2 sensor to the motec m600 and using aux output 1 for the heater.. It will not read anything and it wont heat up even on fast mode. If i go to test outputs I can get the sensor to heat up just fine but it wont on its own and wont read anything for me to do a air calibration.. I have checked and double checked that the wiring is right... any help would be appreciated...

thanks

Is Lambda Enabled on your ECU?

That turned out to be the problem I bought the ecu second hand and everything else was unlocked but the lambda..
