I've been looking for this test page in tuner studio to find what the open and closed (DC) percentages are?

How did he get this window? I know he is using microsquirt but how much different is it?

This is a MS1 ecu I am using

Any questions about my specs that may help answer my question just ask. Still learning here so work with me

MS1 doesn't have any test modes. Consider upgrading your ECU to MS2.

Generically bosch 2 wire run well at 30-35 "hot" and 50-60 "cold"

With no output or uplugged they are fully open. You can find the closed point by starting with output at 0 and ramping up until the motor stalls (if no other bypass) then jump up 10-20% and find the same setting going down. The closed duty is approx halfway between.
