Ok, I have a jrsc on a b18c in my hatch. Hondata s300 running a jrsc basemap for my setup. The car when turned on revs up to 3k before settling down to an idle of 900 rpm's. This is when the car is cold. Before settling in at 900, the revs move up and down for a few seconds. When warmed up, the car is idling around 1500 rpm's. Randomly, the idle will jump up to 2k, and more recently, 4k!!! Any idea?
