I need to clear this up, I'm a little confused.
How are short term 02 trim and long term trims "added" on 1g's. If my long term Lo Trim (idle) at 83% and the 02 trim (short term) trim oscillating between 95 and 106, that means the ecu has stabalized the A/F at 14.7 by constantly pulling fuel out? So the goal would be to have the long term trims around 100 and the short term trims oscillating between 95-105? -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

To get the total trim, you would do low + O2 / 200
In your case yes it is taking out fuel at idle. You want your long term trims to be 90-110 and your O2 to bounce between the same. Low is used 0-100 hz mid is 100-200 high is 200-open loop so basicly mid isn't hardly used at all. Hope that helps -------------------- GVR4 866/1000 = the perpetually broken car
