Anyone have any suggestions on what to look at to get my custom Sony remote interface to work more consistently? I have four buttons - two buttons work consistently and two buttons occasionally.
I’m using a Porsche tiptronic steering wheel (I don’t have a tiptronic) with resistors inline with the buttons to interface the empeg.

Here is what I have so far:
1. The empeg works fine with an actual Sony remote.
2. The resistor values are within the range in the FAQ.
3. I get a resistance value at the 3.5mm stereo plug every time I press one of the buttons.
4. The codes show up in Hijack Button Codes Display when the buttons are working.
5. I am using 2.0-13 and Hijack v300
6. I’ve read/searched the FAQ and the board but have not come across anything that helps.
