The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.
Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.
However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Feel free to search the forums for information, facts, and overview. While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. What has changed is that the method of MegaSquirt support today has rapidly moved to Facebook, this is where the vast majority of interaction is happening now. For those not on Facebook the msextra forums is another place for product support. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.

Once idle fuel is tuned properly, and idle speed is set correctly, there is no way MS can cause a higher idle speed unless it's opening a fast idle valve. Your engine must be getting a bunch of extra air from somewhere to idle above 2k. Vacuum leaks (as already mentioned, or a disconnected but leaking IAC valve might be to blame.

Roger.
My bad....the topic kind of took a turn in a different direction. The idle problem is solved (for the time being). The problem now is my either my IAC seems to be malfunctioning…or my ecu.
I may just end up posting up a new question if I don’t fine the answer after searching.
