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.
This forum is for discussing ignition setup, tuning, and troubleshooting for MicroSquirt (TM)

Last September I upgraded from version 2.891 to version 3.780. Since then the AFR1 and egoV1 values don't change. The log shows egoV1 staying at a constant 1.00 and afr1 at .823 lambda. I noticed that the egoV2 value shows the voltage I would expect from the LC-1 for my running AFR. Did I do something wrong when I installed 3.780? I have attached the latest .msq.
The only thing I can think of is that you have to have engine synced and rpm above cranking. I ran your msq on the bench and when I change the ego1 pot the AFR gauge changes. The only other thing that affects it is the calibration. You lose your ego calibration on a new download.
