OK Ladies and Gents.....

First of all, sorry for the lack of the Tom Brokaw or newscaster voice tone, but as Thumper would say, it's......Thumper Just ME.......By The Way.......if anybody has some shit to say about it..... ............. ....feel free to do so.

Second....for those of you out there that didn't believe the importance of the neutral switches circuit (failure code 67) for a proper idle control, prevent the infamous rolling/surging idle till it stalls condition, etc, etc........here is the proof. If this is not proof enough.....Sad Sigh....I only have two words ....................shock therapy.......  Whistling 

Third.....special thanks go to "Defacto_pr Productions"... Cheesy...  for providing the HW/SW we will use to "document" all the SBFTech/Fordstrokers/CI/Thumper/etc projects we have on the works for Jibaro's Project SOS, his FI SN95, and the long term plans for both under Quote-Unquote design right now.

Sooooo...w/out further adue .....here it is.

Joel, my car was an automatic and a t5 swap was done. I can start my car without engaging my clutch, so I think that switch isn't connected. Will it cause the same effect? I have had idle issues but it seems that a lot of iac cleaning and idle adjusting has minimized it.

It will depend on what pin 30 at the ECM is looking at....... if it's a ground signal pin 30 is registering, it shouldn't surge as a cause of the NSS. LUK

I have no idea. I did an A9L swap on there and removed the T4MO. I'm not sure if that affects anything, but since I don't have the car I was just wondering.

Yo-el! 

Hey, for lack of FUNDS...I have no soundcard in my computer so maybe I can just ask and you could "reply."...lmao!!

SO, I'm still seeing a few (read:more than I'd like to have) issues with idle, backfiring, throttle response...etc...

I have the Neutral Safety Switch "jumpered" with what appears to be a plug that just connects the two wires to complete the circuit. 

What the narrative reads to me is that this could cause some issues>??? 

My safety switch is gone from the car so would it behoove (sp?) me to buy one and set it up the correct way??

Thanks for the knowledge as always,
Ivan

To prevent damaging the SIGRTN circuit on the ECM PWB, as experienced at http://sbftech.com/index.php/topic,14708.0.html .... make sure you install the jumper wire to the white connector (the one for the ECM signal), and not between the two connectors of the clutch pedal switch assy...... or as shown below.

This may sound silly, but is this situation similar with AOD eqiuipped cars due to the NSS on an AOD?

joel knows way more about the fox ECM logic,  but im gonna take a stab at it Smiley

i know that the A9P (auto) and the A9L (manual) ECM's have a little differnt timming table that adjusts the timming when the AOD is in gear vs not in gear.  I think it is very possible that the A9P uses 1 table when the car is not in gear, and another timing table when the car is on gear, controlled by the NSS so the ECM knows its in gear or not.

i could be wrong, if i am sorry

Yep..... auto setups also use pin 30 as an input to ID/establish load condition.
