OK, so the idle issue is still the same?

Yes, idle still rises above set speed with 91 anned tune.
I loaded my I2 modified stock tune. No idle issues, but with this the catalyst monitor becomes "not available". The other 7 monitors are there and appear to be unaffected.

I will need to flasb it again as I put my working tune (modified stock) back. (Daily driver)
FYI, that custom tune is with CAI, and currently I have a stock 2013 airbox on the car.

Car would not stay running after initial flash. I had to reduce mass air to get it to run and not max out short term adaptives.

This is the modified stock tune that has no drivability or idle issues. Adjustments made using the "modify stock tune" option from the I2 menu. This runs very well, but,

The two issues with this are:
1, disables the Catalyst monitor. Only have 7 of 8 OBD monitors.
2 Cannot make any adjustments to cam timing, device crashes/ generates error when clicking "apply". (see my other threads on both of these issues.

Additional info: My I1000 behaves exactly the same.

This is the last tune written, the 91 Custom.
This has all 8 monitors, runs great, but idle is above set speed. (same as loading 91canned) Check engine light will come on after about 50 miles with "idle control, idle speed too high. I think it was P0504 or 505.
It only idles high when the vehicle is stopped. As long as idle control is "dashpot', idle is at set 650. 7 seconds after coming to a stop, idle control switches to "learn", and idle rises to +100.
