Hi, I am trying to eliminate rev hang on my CR-Z by reducing the "Overrun fuel cut delay" but when I tried uploading the calibration there is an error code "P2467 - VTEC Oil Pressure Switch Circuit High Voltage" and my dash panel gives me "CHECK EMISSION SYSTEM" message until I revert it back to stock ECU setting.
Question is:
- Am I doing correctly t oeliminate rev hang by reducing the "Overrun fuel cut delay"?
- Is there any parameter to change in order to eliminate rev hang on CR-Z?
- What needs to be done to correct the error code P2467?
Thank you Guys!

Re: Rev Hang for Asia CR-Z
Thank you for your response. I am using stock ECU and uploading Flashpro "CRZ-Asia-1" base calibration.
Re: Rev Hang for Asia CR-Z
The fuel overrun cutoff delay values are 60ms - you can try reducing these to see if it makes the rev hang better.
Does your vehicle have a VTEC oil pressure switch? If not, disable the test under VTEC / Options.

Re: Rev Hang for Asia CR-Z
I'll check whether there is VTEC oil pressure switch on my model. Is this not a standard for VTEC engine?
I tried reducing the Overrun fuel cut delay until 10 ms and I got rev hang almost eliminated. Will this value be bad to the engine?

Re: Rev Hang for Asia CR-Z
Not all engines have VTEC oil pressure.
This will not hurt anything, it just makes it more drivable.
