Lambda Wiring? Also sputtering, stopping below - 3 celsius.

#1 Post by Norway_Tahoe » Thu Feb 21, 2013 11:29 pm

Greetings from Norway! :D

Hello, i have a 2001 Chevrolet tahoe, 5.3 litre with a BiGas sequential system. the system are not using lambda input to the BiGas ECU, but planning to do this.
Is there any benfits using Lambdas into the Bigas ECU really?

How do i wire them up? Could i just tee them into the cars existing lambdas, and they will work side by side?

Also having problem with sputtering and stopping when outside temp is -3 celsius, and revving down to intersections, red light stops and so on. Cooling fluid is ok, reducer temp is 81, gas temp is reading 21. Is 21 to low?

:D Any tips helping me sort this problem out is most appreciated! :D

The only benefit to connecting the lambda sensor to the Bigas unit is that the lambda output is then displayed on the Bigas software as an aid to troubleshooting, it doesn't have any affect on the running. It simply means that you don't have to display the lambda reading on another instrument to see what it is doing.

And if you do wire them in make sure you only connect purple wires and not the grey ones.
