I have a K20a2 engine with ITB, Je piston rc 12, Toda A2 camshaft, PRA ecu and Kpro III.
The engine run fine, idle ok at 1100 rpm and i use Alpha N setup. at light % of tps (3-4%) i have a fuel cut at 2000 rpm..if i use a little more % tps (>5 %) the engine rev normally..
The map sensor is installed and plugged in a runner, i have no IACV installed on the harness.The TPS sensors is a new Ktuned. i have check the wire and it's ok.
I have try with a PRA kal, and only for test a PRB kal (hondata Alpha N)
I have set the protection at 0 Kpa for disable them..
I attach the datalog of issue and the kalibration.

Re: ITB and fuel cut with low % tps
Disable the idle valve.
Fix or disable the o2 sensor.
Set the Overrun Cutoff tables (Advanced tab) to 15 kPa or so.
Rotate the TPS sensor so that the minimum value is closer to 0%.
Something looks odd about the MAP sensor. 30 kPa at idle is low for a ITB setup, and the way the MAP doesn't increase with rpm seems odd too.
