With it in limp mode with the TPS unplugged you should be able to get a timing light on it and get your base timing set too. I noticed your distributor bolts are all the way loose and it's fully clockwise.

There are some pictures on a timing chain replacement on a KA24E complete with distributor installation.

Lastly, most people aren't willing to dig through your old posts to find out what all you did to your car up to this point. You never said anything about replacing the TPS in this thread and I believe that IS significant. Whether you succeeded in fixing the issue or not. The inputs your car uses for the closed loop maps are coolant temperature, throttle position, engine speed, and airflow from the MAF. There are lots of other small things like the knock sensor that can change the tables too.

The point being, while it didn't help YOU fix the problem, it helps the people you're asking for help understand what has been done up to this point. Also, if someone has this issue again and does a google or forum search, the chances they hit one of the 'uncompleted' threads is likely. Why not retain your issue to a single location so that others can benefit from the solution too?
