Did you do anything special? Before I installed ktuner my trims were always spot on 0, but after installing TSP stage 1 they are constantly trending positive. I almost always have LTFT of 1-3% and STFT of 3-7%

Also how are you getting a knock count readout? I don't see it as an option in tunerview at all. Is that a ktuner 2.0?

View all

Fuel Trim is the adjustment the engine computer (PCM) makes to the fuel mixture to maintain a balanced air/fuel ratio

No I have not done anything special. I just used a stock intake. You can choose which text you want to be shown. In this case you want to choose the K. control and or the k. Count

I'm using tunerview on the head unit and it doesn't have knock count as an option. I assume you're using a ktuner 2.0?

I guess I complained too soon, I went for a drive this morning and my trims kept going back to 0. I guess 1-3% for LTFT and 3-7% for STFT are within allowable ranges anyway.
