Thanks Jim.
The problem with my coding plug is that the 5sp plug has an extra pin that the auto plug doesn't have. I opened it up and the wiring already exists for the pin that's needed, and it would be easy enough to solder. But I don't have a pin. So I figure for the $10 or so I'd pay 928 int'l for a new plug, it's worth it to not have to try to chase one down.
I guess what I need to do is more logs. Lots more logs.
One more question--I have several cells that aren't ever touched by the sharktuner at the highest loads. I'm assuming that permits tuning/expansion for even higher horsepower cars that are running an even greater amount of air/fuel through them? I ended up moving the 13 AFRs higher up in the target map since I wasn't ever seeing loads in the lower rows...

Hello Brian,
The SMAF maps are designed for a very high power capabilty. Also, the law of airflow vs row is not linear, it becomes cramped as the load increases. So there's a big diffience in airflow between the last few rows.
When John Juhn was tuning his twin turbo with SMAf he was getting onto parts of the bottom row at 575rwhp. (about 660crank HP.)
