fuel - tuning 1st column

ok I have finally gotten the hang of the hondata system and have gotten pretty good at it. The only thing I am having trouble with is tuning the first colum. I can never get the motor in that colum to get any readings on whats going on, even at idle. I am at about 280mb, 800rpms at idle.

The only reason I am concerned about this column is when let off the throttle, say in first gear at low rpms and start to apply throttle the car jumps. at around 1-4 % opening of the TPS it doesnt feel like the engine is doing anything then around 5-6 it just jumps.

Any advice would be appriciated

oh btw I have a stock JDM b18C

What is your TPS voltage at idle?

Try adjusting your TPS so that it reads .49 at idle. Also try disconnecting your idle control valve when the car is warm and idleing..it should idle at about 400-600rpm, if it does not you have an air leak.
