1G How long does it f@#$@%# take to get your fuel trims to move

Okay so It says in the posts that I read to sit in your car after you drive it for 10 minuites and then your stft will begin to shift. I do this after I reset the computer freaking takes forever for the things to change then they go up to 138.9 but my pulls on my logger look like this.


O2-R TPS RPM KNCK TIMA
0.84V 63.1% 3813 0 27°
0.88V 71.0% 4031 0 25°
0.88V 77.6% 4125 0 20°
0.88V 85.1% 4313 0 17°
0.86V 100.0% 4531 1 16°
0.86V 100.0% 4750 0 16°

If that 138.9 wuz a stft # and your o2 is reading like that on accel you might have a prob, Your o2 level should be just on the lean side when accelerating that means they have to be below .45 and on deccel they should jump up to where they are @ . log and idle give me 02 mv and stft and give me the same for 2500 rpm steady in neutral with no load on. If the datalogger is that slow can you eliminate some of the readings to get faster response. I use a scan tool MODIS to diagnose vehicles and I can customize the data list which lets the numbers react closer to realtime. The stft should jump on pretty quick although I don't have experience with dataloggers yet.

most people reset the ECU to clear out the LTFT's
