Hello
I tuned my car with S300 V3
My setup is nitrous dry with S300 manage the fuel from 425cc injectors .
While i did some pulls to fine tune the nitrous AFR i found at a datalog that nitrous in ON when i close the throttle to shift to next gear.
My TPS minimum for nitrous ON is 98% while this is ON at 47%
This makes me nervous as i am afraid for lean AFR conditions.
I use the 2.7.5.0 software version.
What i describe is happening at 54 sec of the attached datalog.I added also a comment there for reference.
An other query about the nitrous parameters is if i choose to disable nitrous at check engine light will it close also when shift light is on ??
Or shift light use other code not affected by check engine light ??
Let me know what you think for the issue at the datalog.
I can send the calibration by pm if anyone wants it.
Thanks

post your calibration as well.

calibration attached.

I think what you are seeing is slight(miliseconds) hysteresis, of it seeing the values being met to keep nitrous on, then it sees the values drop and it does in fact turn it off.

Then you think that this is acceptable and not a malfunction ?

It is only on for a single frame of the datalog, I would not worry about this.

If i choose to disable nitrous at check engine light will it close also when shift light is on ??
Or shift light use other code not affected by check engine light ??
I searched parameters help session but no info found.

More than likely anything that triggers the check engine light would cause it to cut out if that is how you have it set. I do not have a test bench to be able to test this. You can try it and see.
