  • SAFC wiring issue.

    I am still trying to get this in my car right and I am looking at the instructions from TSN, but having no luck finding the ground I am looking for a tan/whte wire at pin 73 but pin 73 is empty and there is like 3 tan/white wires. can someone give me a good solution to this problem, I really don't want to put my car back together again just to have to take it apart later.

    Pin 76 and 77 should both be grounds and colored tan/white. Those will work in place of 73...pick one or the other. Pin 73 I don't beleive was landed on all 00's but should be on 01/02's.

        dude if you need a ground just ground it to the frame somewhere, that's simple shit so don't stress

            got it all in and setup now I need to tune it! there was a link on TSN on what others used for their vehicles, I remember 1 was same year I had with no mods I wanted to copy that as a start before my WB arrives. any ideas?

              wait for the wideband o2 if you want to play it safe, just a thought.

                yeah you are right! I was just reading around old articles and realized my knock sensor is reading exactly 100 over the recomended both at 1500 was 1: 126 and 2: 138 at 3500. anyone know why or if something is wrong?

                  I would highly suggest grounding it like the guide says using the PCM wire. without doing so you WILL have grounding problems and sensors not being exact because of that whole grounding 1 in apart thing.

                  You already did the calibrate? Drive for 10 minutes, put it in park and do the calibrate acording to the guide. When done at idle in park it should read like 0 - 2.

                    I'm not understanding this, why would it have grounding problems? I'm not saying you're wrong Alan, but I am not understanding this.

                      To get accurate sensor readings the A'Pexi manual states that you must have two grounds, one inch apart, using the same ground that the PCM uses. One ground wire goes on the PCM side, on goes on the actual car ground side. From how I understand it the SAFC uses the difference in readings from these two wires like a calibration factor for the sensor readings. Ground them to the same spot and you lose that calibration. When someone says the sensors arn't reading right 90% of the time they inproperly grounded the unit.

                        ah ok that makes sense

                        just for the record, if its for sensors and/or specific readings, I wouldn't ground them together, I was suggesting he use the frame with howeever many points he needed (thought I might have left that out).

                        thanks for clearing that up though.

                          yeah the 10 minute drive thing helped alot down to 60 and 73 respectvely, thanx. Haven't found a good mountng point so for now it is in the vent awaiting the WB then I'll figure out the mounting local.

                            I took the bracket, reversed the pivot and bent the one side. Then I painted it to match the car and mouted it with little bolts to the dash. The end of the wire has that big head on it so I made a big hole but its all hidden under the bracket:

                              sprint; I've been readng up on TSN all the work you put in to get the walkthrough in, great job it made the install real easy. I am liking where (yours is good) I placed the SAFC on top of the middle vent (for now). only big issue now is the color, how the hell do you change the white to blue like the box says but there is nothing mentioned in the instructions or scrolling through the menus.
