I've been locking in mapped points and tuning the SD tables individually. As I started dialing them in, I began getting all this IPC error.
I've been using a method I found somewhere on the forum to tune the TQ maps and using the built in calculator to populate the inverse. This helped a lot, but not completely.
This morning I extended out the torque axis on my inverse table then used the built in Inverse calculator to populate the table. My IPC errors almost vanished, but it threw my SD table way out of wack. I'm going to try and bring it back in line tomorrow.
One thing I notice is that when I finally seem to get the SD tables dialed in, the engine starts to run away at low loads. Any suggestions on the cause and how to tune this out?
Thanks for any help, I'm learning as I go.
