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.
My CHevy Beretta has a MAP sensor and is not listed in the megatune list I think.
When I set the sensor in the ini file and in MT on 115, then it reads about 115 kPa.
When i add vacuum on the sensor it drops values till very low.
How do I get info about my sensor. It have 2 of them now and both same number on top : 466 and the GM logo.
Found on Eric's site the 3 bar version and this is reading all wrong ( above 300 kPa )
Think I have a 1 bar version or some like because the value shows up at 115 kPa at sealevel ( should be about 100 kPa now here )
Yes, removed the 4250 sensor and wired the GM on onto the board testing.
Just measured the output and it gives about 4,96 volt at 100 kPa.
Think it is a 1 bar absolute type.
Also reviewed the lookuptables, but can't get how it is build exactly.
