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.
So the Toyota IS300 has separate wires for EACH shifter selection that all go high (12v). For the standard 4 inputs on the Megashift I built simple voltage dividers to bring it down to something more PCB friendly, but the wiring of it has me a bit confused. The toyota ECU has the following shift selector options:
P
R
N
D
2
L
All of which have their OWN wire that goes high when in gear. The others remain low. They also are responsible for running the gear position indicator on the dash. I'm not exactly sure how to configure this?
Right now I have it wired with only 3 inputs (all I built so far).
You only absolutely need PNR. You can shift to the lower forward gears whenever in drive by using the shift buttons (this is the way the code expects you to shift, using the lever can cause all sort of niggling problems, like indeterminate shift lever states).
