Fuel pump percentage > 100??? Weird ... Load is also weird ...
Ha, yeah, can't answer the question on the fuel pump percentage. It has been consistently reading over 100 ever since I started data logging with the SCT. I thought that was strange, too.
Is one load particularly weird over another? For the 0-100 pull I was on a stretch of road that wasn't very flat. I'm thinking that variation might be the uphill/downhill. I've since started running just 0-60 on a flatter road section for improved consistency. I can re-run the 87P1 tune 0-60 on a flat stretch, if that will help.

When you see positive knock numbers it is pulling timing because it is sensing incipient knock..
When you see negative knock numbers it is adding timing until it senses incipient knock...
The knock sensor just searches for the beginning or the start of knock... It adds or removes timing accordingly..
Negative knock reading = good
Positive knock reading = bad
This was my impression based on the reading I had done, which is why I was confused that it was recommended to run the 87P tune over the 87P1 tune, since the 87P1 has much less KR at 60 mph.
Is there something else I'm missing on the 87P tune that would make it preferred over the 87P1? Thanks for the feedback, guys!
