Just a data point on the MAP sensor issue above: there are two fueling strategies used in electronic fuel injection. One uses a MAF (Mass Air Flow) sensor as its main input, which provides actual airflow, air density, air temp and baro. The second is MAP (Manifold Absolute Pressure), which uses engine vacuum and then makes a guess on actual airflow based with TPS and RPM from a pre-programmed fuel table. MAF is way more accurate, but also more expensive. These bikes use the MAP strategy and it the MAP is unplugged or erratic you will get really funky idling and fuel delivery as it’s using the wrong fueling map for the actual conditions.
It was a little thin tube that went onto sensor, it was running really lumpy before I re-checked everything. Despite being 2015 I did also add the resistor, I happed to have one so didn't see any harm putting it on there.95% sure it was the MAP sensor. Was the module attached to the airbox? The tube plugged in the bottom of it?
