exileperformance Posted July 23, 2018 Report Share Posted July 23, 2018 Has anyone setup ecu to control automatic shift functions? I have search a little and haven't found much. I would think it would be a matter of getting inputs and outputs setup, if someone has something I can work off of that would be great or I will end up smoking a few transmissions but I will share the results lol. Thanks for any help. Quote Link to comment Share on other sites More sharing options...
JayGow Posted July 23, 2018 Report Share Posted July 23, 2018 I have been running shift solenoid control for a while now (BTR 4 speed), with torque limiting during shifts as I don't bother with line pressure solenoid control. Works great! Obviously factory style automatic shifts would be a challenge to set up and time consuming, but setup for full manual control is simple enough.

Drexal Posted July 23, 2018 Report Share Posted July 23, 2018 Id be interested in this as well, I'm currently running a Re4r03b gearbox with a R34 Skyline trans controller. It seems to work but would be much nicer to be able to get the Link to do the control. Quote Link to comment Share on other sites More sharing options...
exileperformance Posted July 24, 2018 Author Report Share Posted July 24, 2018 I think you could run line pressure based off the map sensor. and I feel like there will be some setup time but I think I can make it shift like stock. the 4l80e has 2 solenoids A and B for first gear A needs power for second all are off, for third B is on and for fourth both a and b are on. The you have the lockup and the line pressure. Quote Link to comment Share on other sites More sharing options...

exileperformance Posted July 24, 2018 Author Report Share Posted July 24, 2018 I would like to be able to setup a tps and rpm table to control shifts. is that possible? Quote Link to comment Share on other sites More sharing options...

Sorry, no we dont have any functionality that will do this cleanly. Quote Link to comment Share on other sites More sharing options...
