If you want more oil from the pump you can go to a 2 or 1.
I was pretty curious about this so I reached out to Polaris. They told me that a
higher offset value provides a higher oil flow rate.
If this is accurate, I don't recommend decreasing the offset number. It would be good if someone did some independent testing on this or if EzLynk could chime in, as I guess it's possible that EzLynk's calibrations are not a copy of the Polaris offset calibrations, or they are named backwards vs. those in Digital Wrench.
Polaris also told me the following:
The offset number is dedicated to a particular pump, not sled model. Flow rates are determined by the pump manufacturer. If a pump is replaced, an ECU recalibration is needed based on the offset number provided on the replacement pump.
If this is true, it's important to match the calibration on the pump, not the ECU (unless you know that the pump has never been replaced). An 001 calibration won't necessarily provide the same oil rate on one sled vs. an 001 calibration on another sled...
