GTTuner Posted December 8, 2006 Share Posted December 8, 2006 I dont think it's a map issue. All my car needed was a thinner gasket on the neutral switch. Works perfectly now. Link to comment Share on other sites More sharing options...
CombatCQB Posted December 8, 2006 Share Posted December 8, 2006 ^2nd that Shimmed my neutral switch and no problems since. I have a rev D ecu for the radiator fan fix and AP stage1. Link to comment Share on other sites More sharing options...
phoenix96 Posted December 10, 2006 Share Posted December 10, 2006 I dont think it's a map issue. All my car needed was a thinner gasket on the neutral switch. Works perfectly now. Maybe there are different problems? I logged my car and it is a NPS issue (shows up as ON almost all the time, so cruise control will never activate). I didn't try trimming the gasket/washer on the switch, but I did replace the switch and it made no difference. Maybe it is worth pulling it out again. phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

phoenix96 Posted December 12, 2006 Share Posted December 12, 2006 His post is 50% misinformation AP V2 will not have this issue Is that because the new base maps that the AP V2 uses have the fix already included? Or does it somehow just apply the tuning changes to your car's existing software? (Because clearly I don't have the Subaru OEM software 'fix', I'm wondering if I switched to an AP V2 if it would solve the problem or if I would have to take the car to the dealership to get the ECU flashed first) phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

No, the new switch comes with the thinner gasket required. I think the gasket is also avail separate. Let me know if you need an PN for it. It MAY be a TSB, not sure.

Let me know if you need an PN for it. It MAY be a TSB, not sure. That could be helpful, actually. I replaced the switch but the new part I got was exactly identical to the old one, so maybe I inadvertently bought an old-style NPS. phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

Max Capacity Posted January 5, 2007 Share Posted January 5, 2007 My early 2005 GT Wagon has a newer ECU because of the fans sticking on. I have had AP installed since Dec. 04. Last month my car began dropping out of cruise sometimes. Seems to happen mostly after going down a long hill. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

pdw Posted May 1, 2007 Share Posted May 1, 2007 Has anyone attempted to fix this problem by short circuiting the neutral postion switch? So, hack the switch so it always tells teh ECU that the shifter is in gear? I ask this because the dealer has a flash that will just ignore the switch. However, there seems to be a problem with the AP overwriting that flash. Any thoughts? Link to comment Share on other sites More sharing options...

However, there seems to be a problem with the AP overwriting that flash. Any thoughts? That might be my next attempt. Any negatives? Obviously, if the cruise control was set and you somehow got into neutral that wouldn't be good - but there's also a clutch sensor that should disengage the cruise control, right? phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

Yes, there is definitely a clutch sensor. Also, I suspect your worried that the revs will climb as if it's floored in neutral. They won't, trust me. They'll climb much more gradually.

They won't, trust me. They'll climb much more gradually. That's good to know. The other question, I guess, is how exactly to short out the switch so that the car thinks it is never in neutral? phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

As soon as I can find the time to jack the car up and pull the switch, I'll figure that out. Or, I should say, I'll pull the switch and bring it to my dad. He has an EE degree from MIT so I think he can figure it out. Link to comment Share on other sites More sharing options...

Or, I should say, I'll pull the switch and bring it to my dad. He has an EE degree from MIT so I think he can figure it out. The switch is a simple two-wire deal. It seems to be an open circuit when the nub end of the switch is not pressed in, and a closed circuit when it is. The problem I've identified by logging the car's computer is that the NPS reports "1" almost all of the time, indicating the car is in neutral when it is not and thus preventing the cruise control from activating. Maybe simply unplugging the switch would be enough to make the car's computer think it is in the "0" state all the time and therefore fix the problem? That seems too simple. phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

phoenix96 Posted May 9, 2007 Share Posted May 9, 2007 Will the car start when it isn't in neutral? Yes - the car won't start unless the clutch is in. The clutch sensor is separate from the transmission's neutral position switch so it shouldn't matter if the NPS thinks the car is in gear. phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

That'd be sweet if it works. So just unplug and zip tie the plug to something so it's not flapping around. I *might* have time for that this weekend.

I *might* have time for that this weekend. I tried it this afternoon. The bad news is that it did not fix the problem. Of course, it does make sense that when the switch is not pressed in, it would be in neutral - that way if the switch were to fail, cruise control would shut off. I guess it's back to shorting it - stick a resistor in the connector? phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...
