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.
A forum for discussing applications and implementations of the MegaShift transmission controller code for the GPIO from B&G. This can control up to 8-speeds and 6 shift solenoids (plus a 16x9 table for controlling a PWM line pressure valve). It has manual and fully automatic modes (16x9 load x speed table), with under and over rev-limit protection, and full data logging of all inputs and outputs (among many other abilities). A TransStim to test your completed board is also available.
I just installed this but slightly older version of tranny in my road runner behind my 440 and I have driven it a little just not into 4th on the highway yeat. I may need to upgrade to gripo for it we will see. I am lucky mine is the simple one without presure control and the lockup (although I would like the lockup.) looking forward to see how this works.
Any luck with the 47re control? being able to use a 46re, 47re, or 48re transmission would open up a lot more options than just a 1994 to 1995 46/47rh transmission for my 1972 Dodge Charger project.
I have this running/driving now, though I don't have the GPIO part completely implemented yet. I'm currently running the TCC, OD and GOV solenoids off the MS3X just to confirm it would work. I just received the rest of the parts to complete megashift today so hopefully I will have it working as it should be soon (as in a week, not 2 years!). Having a driveable car helps a lot with motivation.
Note: Running a RE trans without governor control results in 3rd and manual 2nd only. Manual low will not work.
Eric, Your reply is greatly appreciated. To begin, what GPIO board BOM should I buy to get started? Interestingly, I also have a 68rfe that I would like to use and I think I will start with the 47re. I just learned that the 45rfe, 545rfe and the 68rfe use the same valve body solenoid package and sensors. It looks like the 68rfe--6speed just uses different solenoid engagements than the other 5 speed trans. So, fyi, if your project is a street machine, the 6speed may be off interest. Too early here to even think of the new 8 speed!
