if one side of the motor is always richer than the other ( under wot), is the individual fuel trim off idle what I need to adj , and if so any suggestions of how much I need to change the multiple by, to raise or lower the mv by 50 or 25, and if this is not what I need to change could someone tell me what one to use

 

c'mon some one knows , someone has to

 

has anyone ever changed these tables in tunercat? is it a big deal that one side of the motor is richer than the other side@ WOT by 30 or 50 mv?

 

how do you know one side is richer than the either? if its rich at WOT then its rich during normal driving too so what do your BLMs look like? i think there is a way to set the individual fuel trim for each cylindar but i wouldnt touch that if i were you b/c you could be dealing with an exhaust leak.

 

Hello,

I have changed the 1,3,5,7 from 1.00 to .98 for 1 and .97 for 3,5,7. I also had a split on the O2 readings. It is hard to know for sure but I think the split is smaller now. I have not dared put these values low enough yet to be sure I am doing any good. I am running an open loop tune right now and do not have it completely zeroed in either. I have raised my mpg from 15.5 to 17 running open loop all the time.

 

i wouldnt go by the stock injectors that close together. i would out a wideband on bit sides then see wha it says
