Re: 4l80e build; output solenoid A and B issues

Thanks for the super quick response. I went back though my datalogs and noticed that my PC% control on this current tune was lower than when I knew I was in first gear on that previous tune. So I upped the table range to bring the bring up the PC% at lower throttle openings. I also noticed I had the...

Re: 4l80e build; output solenoid A and B issues

I got a chance to do some more digging over the weekend. I have confirmed that the transmission is not able to get into first gear. I did this by wiring up the transmission solenoids A and B to toggle switches. I turned them on/off as per sequence in each gear. I successfully have gears 2, 3, and 4 ...

Re: 4l80e build; output solenoid A and B issues

OK, I did about the worst thing a person who is asking for advice can do, which is let the project sit for a while. But I finally was able to do some testing. Here's what I did: -I checked the voltage at the transistors and found 12 volts on the outside legs, so presumably the wiring from the trans ...

Re: 4l80e build; output solenoid A and B issues

I too started having canbus issues between MS and GPIO through Tunerstudio. I'll be interested to see what the fix is there. For now I added a DB9 to the GPIO, so I can keep working with it. I'll plan on upgrading to the current 5.201 code and see if that helps. I'll also check the voltages on the t...

Re: 4l80e build; output solenoid A and B issues

Thanks for the reply. I have not had a chance to check it out yet, although I don't have a signal generator so any troubleshooting I'll be doing will be on the vehicle. I was using a multimeter to check voltages and resistance in the legs of the transistor. I was careful to not touch multiple legs w...

4l80e build; output solenoid A and B issues

I have completed my Megashift build and install, but the output solenoids are not working as expected. I have jacked up the car and tested the trans, and have in some instances felt it shift through all 4 gears. But when I get on the road, the shifts do not seem to correspond with the shift table. I...

Re: Unable to get MSGPIO and MS2 communicating after TunerStudio Update

Please see attached my project file. Let me know if any of the CAN settings between MS and GPIO seem to be incorrect. Note that I changed the file extension from .tsproj to .pdf to allow it to be attached. For some reason the board would only allow files with certain extensions to be attached. This ...

Re: Unable to get MSGPIO and MS2 communicating after TunerStudio Update

Thanks rukavina. I checked under the project properties page but only found one area where the CANBUS settings can be activated, and that is on the CAN devices tab (page 3). I did not see anything under page 2, as you describe. I ensured that CANBUS communications were set to activated, but did not ...

Unable to get MSGPIO and MS2 communicating after TunerStudio Update

Hi Everyone, New to the forum but I haven't had to post as I've had great luck with my MS2 and Megashift combination - until now. I was running Code 2.920 and MShift 4.127 in my car, connecting using Tunderstuido 2.0.8. I had gotten the combo running 2 years ago, but didn't do much tuning due to an ...
