2011 WRX STI Safe-Mode (Help)
Hello,
So I connected the orange wire to the pink wire as according to the instruction manual in order to use the safe-mode feature, and then set the failsafe pin to FS1. Failsafe is enabled by placing it on DHB. I turn on the car and it immediately went to safe-mode (indicated by the clicking noise and fan turning on and off). Even when the Aquamist system is on it is still on safe-mode. Starting the engine will display CEL also. I tried removing the CLP pin (which should mean it is now 8v) but still no good. That being said, I noticed around the area where the ECU is, there is an unplugged green socket. This is the socket to connect to turn on safe-mode from factory. So that means, when there is 0v (socket unplugged) then the safe-mode is disabled. But the Aquamist manual said, the orange wire by default is sending 4.7v under "no fault" and switch to 0v upon fail-safe activation or the gauge is switched off. Can anyone help how to use use this feature? Note: I still have the wastegate failsafe method wired but I supposed that is not an issue and allows me to choose between FS1 (if it work) and FS0? |

Oh, wait.
FS1 and FS0 is got nothing to do with signal channel is it? Is this more of 0-5v or 5-0v? |

Solved!
The switch to safe-mode during failsafe activation is working flawlessly. |

Hi Richard,
Yes I only realized it when i re-read the manual. https://scontent-xsp1-1.xx.fbcdn.net...f0&oe=5F4EBF93 No more boost to dump when the failsafe is triggered as the lowest boost setting is on wastegate pressure. https://scontent-xsp1-1.xx.fbcdn.net...78&oe=5F4C4D37 Timing immediately reduced when failsafe is triggered as Ignition Advance Multiplier drops to zero. |

Hi Richard,
I read your post at IWSTI forum: https://www.iwsti.com/threads/input-...-hfs-3.188058/ "However, you can use the relay output to actve the car's "safe-mode" instead of reducing boost. Don't forget "test-mode activation" will reduce boost anyway." Do you mean it is the brown/white cable to connect to the safe mode instead of the wastegate? If so, do I just splice the Pink (pin27, socket B) cable and connects both ends to the brown and white cable of the Aquamist? |
