PRA ECU and closed loop

When I disable closed loop in all euro CivicR's I have tuned, the AF ratio is still adjusted by the 02 sensor (giving me a short term correction and an AF ratio around 14.7:1 whatever changes I do to the tables). Is this a bug? It seems that the ECU cannot go into open loop.

Can you send a datalog with calibration?

I'll do as soon as I tune another CTR.

This is a datalog with closed loop disabled. THe calibration used is basically a 'Dyno tuned' for the PRA with closed loop disabled. However, as seen in the datalog, there is still short term fuel correction and fueling status is set to closed after a while.

I had the same problem when my PRA ECU worked
You must to put Minimum short term and Maximum at 0%
