Default Pull idle solenoid connector and idle goes UP?!

Tuning a friend's 1.6 AEM.... I pulled the connector to the IAC and the idle went UP instead of down? Thoughts?

The 1.6L idle valve has a failsafe that does this. Normal, but annoying for troubleshooting purposes.

MS Labs: Plug and Play Megasquirt ECUs for ANY 90-05 Miata (NA, NB1, NB2 w/VVT, MSM), including basemaps to get you started ASAP. PM me or email or details.
For support on MS Labs ECUs: Please email, be sure to include the unit's serial number and include a datalog and your current map.
