Running a rsx gen2 8.5 combo in my 2wd sct.
Truck runs great... Smooth on start up for roughly 6/7 minutes. At that time it cogs slightly from a dead stop. Once moving it is perfectly smooth even at a slow crawl. As the truck seldom comes to stop while on track it poses no drivability issue. Motor temps at mid 160's and esc at 105 after a 15 minute run. I've had the motor apart several times but all seems well.
Once the truck cools it will run smooth Again on start up for 6/7 minutes. Since this started the motor has a different tone to it in the middle rpm range, but not at low rpm and not at wot.
Thoughts??
