I have the first version of controller, I purchased it in 2019 and have just got round to using it.
I am using Maxxecu mini, enabled the correct analog 0-5v channel, I have entered the correct values at 0 & 5 volts.
I have tried another brand to compare results and everything seems normal with that one.
Back to the Spartan - the Lambda read out is stuck at 9.3.
I removed the sensor and tested it on another setup, tried another new sensor and stil its stuck at 9.3
Also, with fuel (on a different controller) checked to see if it will go full rich and lean, and it does
If i rev the engine past 3k the value jumps about and looks as though its trying to go to the desired reading.
I don’t know what to do from here, ive done everything i can think of in regards to the idiot test!
Thanks in advance
