So, to get open loop at idle or during deceleration, with no accel pedal input, you need to adjust load for open loop during deceleration table that I posted previously. This is a correction to what I said previously.
If you just want open loop all the time and don’t want to tweak when it transitions, one easy way is to adjust the time delay for closed loop below:
Just set the right side to 10 x 60 x 60=36000 for 10 hours and you will always be in open loop. I’m sorry I don’t know how/where these tables are labeled/located in your software.
