One of my ASF MR-02 exhibits this unusual behaviour. Any help is appreciated.
First, this particular chassis will not run straight with the steering trim centered. I must set my EX-I UR to R-2 to get the car to track straight. But what is more frustrating is that the left and right turning radius is different. The left turning radius is smaller than the right. This makes the car a lot better at turning left than right. Unfortunately at our track we run clockwise with more right turns.
Is this something that can be adjusted on the ASF board? If so, what do I need to do?
I don't know if this is a fix for your problem, but my car had the same issue. The left to right turning radius was way off. My right steering was fine but when turning to the left it had about half the radius of the right wheel. I was told by a local expert that I should replace the pot... I soldered in a new Kyosho pot and my problem was immediately fixed... I hope this helps..
Thanks for the responses guys! I've tried different tie rods to no avail.
The reason I asked about the board is because on the Gen1 XMODS boards you can adjust the steering pot with a screwdriver. I believe this is true for the MR-02 AM boards as well, but I never had to adjust any. Wondering if there is a screw adjustment on the ASF board for this.
I have a new pot laying around, but was going to see if there were other solutions before swapping that part out.

The AM boards have a small pot on the board that you can use to center the wheels. I am 99% sure ASF cars don't have this adjustment. See the photos in this post.
A bad or dirty POT could be causing your problem, but what are the end point adjustments set to? Did you try what B-main suggested?
Does your car make any funny noise when you turn the car all the way to the right?

There is nothing wrong with having to set your endpoinsts slightly different L to R. This is the reason why you got a high-end digital transmitter. No 2 boards are exact, as well as the parts that are made. If your steerig is off 3-8 clicks to the right or left, this is perfectly normal. Same with steering throw.
One other thing you can try is to replace your servo saver. They have been known to cause erratic behavior on the steering. As somebody mentioned, make sure the wires from the pot are routed properly and that they are not binding the steering mechanism in no way. I sometimes have to recess the servo plates so that the wires can make it around from the pot to the board without jamming anything up.
