Hey guys,
I'm having issues with the setup on my Gen 2 busa. I am trying to use the 2 step in ECU editor, however when I engage the 2 step, the air to fuel rises very high. I've verified my tune when the 2 step isn't engaged and the air to fuel is nice where it should be and very linear. However, once the 2 step engages, the air spikes up.
Everything I've tried to get the air to fuel back down to where it should be hasn't worked. Have any of you run into this?
