So I had posted in another thread the problem I am having with closed loop where the car jumps between rich/lean but is fine in open loop. This problem happened when upgrading to latest version of SManager. (My older version was 2 or three versions old - upgraded last in August or September 09)
The differences in the datalog are Open Loop vs. Closed Loop. The jumping around is in Closed loop only.
I have a D16Z6 turbo'd and the previous tune was fine.
Stock P28 ECU with S300.

peasly23: can you upload your new calibration? I also got same problem with you. What value you put under "rate of change" section? :Dpeasly23 wrote:Update... I upgraded again to the newest version, and still same problem. I searched for Spunkster's calibration, and entered his values under the "rate of change" section and things are running much better now.

in regards to "Rate of Change" is that a motor specific? or is it something I can calculate to enter the values? or one of those trial and error thing to see which values work , I don't know how it works, my car is behaving the same way in the new version 1.4.7, jerks back and forth from 14:1 to 16:1 while cruising either 2500, 3000, or 3500rpm.....any input from someone here in the forum is appreciated....thankspeasly23 wrote:I put the same values as Spunkster.
