Hondata

Sry, My English is not good...

I have this problem if you drive at a steady cruise A / F goes up and down. Open loop is when I use all the normal.

The engine is a turbo B18C6
Precision sc61
RC 750cc
8.5:1
Hondata S300, Innovate WideBand LC-1 XD-16
WideBand input EGRL D12

if anyone can help?

CLOSED LOOP when driving A/F is ok, but if you ride Open Loop A/F goes down to 13.6-16.1
I use the original O2 sensor and the WideBand

This looks pretty normal, the datalog freezes after about 2 minutes 50 seconds

Why driving is a closed loop A/F 14.7 normal but open loop A/F 13.6-16.1 up and down.
I'll make a new datalog which is to better understand.

Has it been tuned on the dyno?

Maximum power is set to dyno but crusie is set by driving on the street

If you feel there is a probelm withteh part throttle tuning then take it back to the tuner that tuned it for you.
