Neutral position switch
Have been advised by a well known mapper that there is a fault on my neutral position switch. In his experience he suggests closing it instead of replacing it with a new one. This to me suggests it isn't a necessary component.
Has anyone else permanently closed/bypassed the switch?

Does a paperclip solution open the switch or close it? My guess is it fools the ecu into thinking you are always in gear. How does this affect the short term and long term running of the car?

Have a look at http://206.13.93.15/STi_Stuff/STi_Ma...%20Harness.pdf
During the remap, the switch was randomly triggering that the g/box was in neutral (i.e. pins 1 & 3 had < 1 Ohm resistance).
I assume the clip was placed across pins 1 & 3 so there was no chance of getting a very low (ie no connection) resistance.
I've got no idea what part the switch plays in the ECU and whether it affects engine running, but the wiring diagram shows it as part of the OBD2 port wiring.

Well what it seems to do is that it shows up as neutral when it's actually in neutral but it when you put it in gear it doesn't always switch off. In any gear you can give the gearstick a back and forth wiggle and it will toggle the neutral switch on and off whilst still definitely in gear.

I fitted a s/hand unit not long after - its only a 10 minute job on ramps.

I'm resurrecting this thread as I still have the problem. The very nice people at Carnetix tested my switch yesterday and my Neutral Position Switch is faulty [as previously diagnosed by mapper on laptop], testing as permanently open circuit.
To replace/bypass the switch on a JDM Sti version 7/8 is a pain as it is on the top of the gearbox not the side.
I'm not getting a CEL light and it's not causing any noticeable loss in performance it's just one of those pain-in-the-*** things you know is there but not sure what to do about it.
If I replace it then it isn't guaranteed to not fail again. But bypassing it seems to be an option. Has anyone out there bypassed their switch? How did you do it?
Does anyone have a source for a switch [other than Subaru] and how much are they?

This problem occured on my old 02 STI when Richard Bulmer was mapping it.
The switch was bypassed and the ecu was reset but I kept getting cel lights and a huge loss in performance. I got a new switch from Prosport for about £32 and after it was fitted and the ecu was reset the performance of the car was transformed and I got no more cels.

Interesting, cos it was Richard that told me that the switch was faulty and he suggested bypassing it. I don't get a CEL light and there is no noticeable drop in performance. However, I've ordered a new one from Xtreme Scoobies. There are two types, one has a long lead, so you'll need your VIN number when you order [unless you know which one you want].
I'll get the nice guys and girls at Carnetix to swop it for me.

Just need to add thanks to Becky and Glenn at CARNETIX for sorting this problem out for me. Top team.
Also probably needs pointing out that on a six speed box the switch is positioned on the top of the gearbox, so the gearbox needs dropping down slightly to access it. I don't think this is the case with a five speed box though. This is also why the six speed NP Switch has a longer lead that a five speed NP Switch.
