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.
Hello, as you may know I am new to this forum so if this is in the wrong place please delete it or move it. I am hoping to both rekindle the conversation about a 47RE controller and get information if anyone has used the GPIO-megashift to control one or what they have learned in the attempt. I spoke to a gentlemen from the tech support of DIY auto tune that told me Lance was the guy to talk to about this 47RE, the place to find him was here and that the "research" about building a standalone controller for this transmission ended in 2012. I have from both troubleshooting 47RE's and research determined the 47RE operates both electrically and it has a TV cable, with this said I think it would be a good idea to determine the exact function and purpose of the TV cable and how it can be correctly implemented when using a megashift to operate the electronics of the transmission. Anyways any help or knowledge would be greatly appreciated. My train of thought is to first get the 1-3 shifting properly then get the OD, Lockup functions working next.
Thanks in advance

I know quite a lot about the GPIO board and the MShift software that runs on, and I even know a little bit about automatic transmissions in general (and a fair bit about the 4L60e that was in my car). But I don't know anything at all about the 47RE except what has been posted here. The best starting place for what you will need to know is here: http://www.msgpio.com/manuals/mshift/newtrans.html and hopefully someone familiar with your trans can help fill in the unknown parameters.

A lot of the Mopar RWD automatics are a bit odd - instead of using discrete shift solenoids, they use a PWM circuit for the governor pressure, with closed loop feedback. It would require a code change to give an option of shifting by pressure control instead of solenoid patterns.
Its a fully hydraulic control body with the EC controlling the torque converter lock up, 3 to 4 shifts, and governor pressure. That all. The governor pressure is control at 1 psi to 1 mph .
The older 42RH - 48RH had a hydraulic governor and may be easier to make work.
