Hello, I am a beginner, I do 2 tunig what should be done with TKATBTS, the catalyst has not been in the past for a long time, but the factory diameter is 2 silencers and the blind chamber is quiet.
The 2nd question concerns the KVB, the car does not display the current consumption, but it corrects the petrol level indicator after exceeding the threshold just above the reserve. The car is powered mainly by propane-butane gas and when it crosses the threshold, it runs on gas
and takes it off the gasoline gauge and thus deceives the driver.
Could setting the KVB value to 0 fix the problem
and of course what about TKATBTS.
