@scottleibrand Hi, thanks for replying. Autotune keeps raising the ISF value far above the amount I need, carb ratio can vary by 0.2 either way to the amount used before OpenAPS. My results are not as good as previously, initially with 0.5.2 they seemed better, then there were various rig and pump problems, then 0.6.0 + ill health, then F40H and the nback on humalog. Basal is good again but eating is more difficult unless it is low carb. Pre OpenAPS I put in about 10g worth of insulin roughly an hour before eating and then applied 'eating soon' with an omnipod + cgm - the results were good. On OpenAPS - a low temp target an hour before before eating and then a similar method putting in the full no of carbs with bout 30g worh of insulin when I eat and leavve the rig to deal with the remaining carbs the rig zero temps very early on for far too long and consequently by BG rises too high. I am dithering now, have changed settings, I did go with autotune settings but it became more difficult and so reerted back t ot the values I thought used to work. I can't seem to get around it and am even considering popping 10g in with a pen before a meal and retrospectively entering that value via nightscout a while into eating. I'm afraid at the moment my methods etc are rather haphazard. I can't seem to get anywhere near the flat lines others have.
Things have improved since reducing the numbers for ISF. Basal is almost identical to autotune and works well,
