this only happens when I lower the cranking value to say 800rpm when the engine is running and then pretty quickly the engine stumbles and stalls (appreciate that I should have included this earlier to give it context).
I’ll try your suggestions around alternate banks whist cranking and see what happens, if the issue continues I’ll get it to 80degrees and set the warm up values to 100 to see if it eliminates the issue. Will log both and see what happens.
