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.

Im sure Ive seen threads on this before but cant find them . Someone can probably answer this quick enough anyway.
Is it normal for duty cycle in datalogs to be > 100% (if injectors are too small). I spent the day retuning for a new injector/cam combo and reviewing the logs the duty cycle is up to 128%.
Not sure if this is normal (eg - 128 is what would be required which doesnt seem likely considering the cam/injectors) or if I've stuffed a setting up somewhere.
Thanks,
Mark.

Stock,
Yes and no. It is an indication of too small injectors, but only if your VE table, accel enrichments, etc., are perfect for your combination. If your VE table and accel are too rich, then tuning them will bring the duty cycle down, possibly below 100% if your injector flow rate is adequate.
