I am using CATS engine tuner software.

In the ECM constants for a $58 bin, what does Maximum Integrator Value and Minimum Integrator Value mean? I am comparing a couple bins and noticed the numbers are different from bin to bin.
thank you,
Mark

 

The max and min values are just the limits on how low or high the integrator can move as teh ecm tries to attain the desired AFRs. Probably jsut leaving that and the BLM at the stock values is fine. Allowing the BLM and integrator to go full span could result in the fueling going crazy if there is a problem with the O2.

 

i just set my max and min values to 128, so that the ecm maks no adjusments to the fuel, my tunning is far more acurate.

you mean you set BLM min amd max to 128 and tune with INT only?

o you are CL and getting NB02 feedback?

please clarify !

yesterday I was running OL with no feedback. today i burned a chip and am CL again with BLM set to 128-128 and using INT only in CL.

 

yes

 

how are you getting the computer to run open loop full time? Min coolant temp for closed loop constant?

 

yes.
