Hello , I have been battling a issue. I have connected my apsx wideband to my kpro v4 everything works correctly all settings in kpro are good and analog input to the kpro reads perfect , but as soon as I crank the engine on ,the analog input for kpro stops reading .. It will somethimes flicker back on and work for a few seconds
Hello , on the wideband I have red to 12v fused, black to ground , and the white analog output from the wideband is connected to analog input (an1) and the settings are adjusted to use this analog , the kpro will show it working properly with key on engine off , but as soon as the engine is started the kpro will quit reading the analog input
The wideband is getting 12v ignition , and I ran a ground straight to the battery ground terminal to see if that helped. But same issue , wideband works properly on kpro with engine off key foward , but when the engine is started the kpro shows its not getting analog signal
Do not use the o2 sensor wiring for power. Use a switched source from the under dash fuse box. There should be extra spots that you can use a spade connector to connect.
