mack85n Posted February 22, 2017 Report Share Posted February 22, 2017 Is it possible to configure an output that modulates up to 5V based on TPS and RPM Axis? I'm looking at ways to externally increase modulation line pressure to my Auto trans when I come on boost.Thanks, Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted February 22, 2017 Report Share Posted February 22, 2017 What are you using for transmission control? Quote Link to comment Share on other sites More sharing options...
Simon Posted February 22, 2017 Report Share Posted February 22, 2017 HI MackYep that can be done, we do this on the BMW plugin controlling the line pressure solenoid directly. Just using a GP PWM output.If its a voltage based control you might need an external pullup resistor. Quote Link to comment Share on other sites More sharing options...

Is there a 3D table that can be set-up for the GP PWM output or does is have a fixed output? What are you using for transmission control?Hi Brad,Just using the OEM Nissan TCU. I was told that after fitting a turbo there will be an issue created where the line pressure to the trans will be lower at lower loads as the TCU wouldn't expect a great deal of load on the drivetrain. When the turbo is fitted this all changes obviously. Have you found this before?Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted February 24, 2017 Report Share Posted February 24, 2017 Yes there is a 3D table that can be configured and the output adjusted. Quote Link to comment Share on other sites More sharing options...
mack85n Posted February 25, 2017 Author Report Share Posted February 25, 2017 Thanks Simon,Sorry I looked into it and its very straight forward. Quote Link to comment Share on other sites More sharing options...
