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.
. went to start and noticed I had lost tune. flashed .s19 and loaded tune. as I was checking all my settings I would open up the vss page and I would get a bunch of different cascading errors from can bus to protocol, then tuner studio would disconnect and when I would reconnect everything in gpio would be rubbish. I have removed and reloaded tuner studio from laptop, I have downloaded and reflashed s19 and ini several times. I posted on msextra tunerstudio forum at first thinking it was a ts issue. phil looked at my comm debug log and he thought it was the firmware. I redid it all again and nothing has worked. before I pull the trigger and order another gpio board can I get a second opinion and any other things I can try? is there a way to do a hardware memory check? here are some of the logs and the s19 I used
I went out today and reloaded everything. ms2 firmware and gpio firmware no matter what I do soon as I open the project with both controllers and open the vss configuration page all heck breaks loose, get a cascade of errors and ts shuts down comms with the gpio. then when I get back into the gpio all that is left of the tune is gibberish. both firmwares are new and tuner studio is the current version. there is a post in msextra/tunerstudio under the same topic. I am about to order another board but I would feel better knowing I have a bad board before I do
Both USB adapters are prolific ftdi adapters running 2008 drivers so they don't have the 2015 driver issues with the validation bit issue. I have had and used both on a regular basis with this. I went and built another board and am installing tomorrow. I had built a vss square wave adapter from one of these posts in 2014. This time I went and changed to a drac module and I need to add 1 wire to the trans loom. Will post results
I am posting in several locations in hopes someone can figure this out. same results. ordered new gpio from diy, built it, other than upgrading to a drac its the same setup that has been flawless for 3 years. so the issue was not a hardware issue with the board.-now I have a spare - I can load tune and configure thru serial directly. I can connect thru can and see data but soon as I open vss page I get can config errors ,corrupted data ( after today I think its in tuner studio only because when I reconnected back directly to gpio it had correct tune- need to verify that) main controller is 0 gpio is 1. I posted in msxtra/tuner studio and phil looked at some comm logs but nothing conclusive ........
so I have reloaded firmware on both the squirt and the gpio deleted and reinstalled tuner studio bought and built another gpio to eliminate a hardware issue redownloaded and reflashed the firmware for the gpio( its the same version for over a year and a half) so if its a firmware issue why all of a sudden and I have used the firmware from when I originally downloaded it and also did a fresh download at some point while trying to figure this out. I am at wits end of what to try and I have not seen a post from lance in awhile. the only one who chimed in over there was matt. I don't know what else to check
