Cut and Pasted together some of Ray's wiring diagrams. How does this look?



Here are the three I used as a guide:






Thanks.

With the dynotune lean shut down switch there is no need for a fpss.

I assume you have a wideband you are hooking to the dynotune lean shut down switch.

Yes Wideband is going in at the same time...so just eliminate the FPSS and run the TT directly to the Dynotune?

hate to say this...but your diagram won't work properly...the timing tuner must see the resistence of the relay coil between the black and grey wires.

something like this...

I was using the Timing Tuner as a Window Switch as well.

How would you suggest the wiring using everything I have on mine...if extra relays are needed, it is not a problem.

I disagree. They both do two very different jobs. The fuel pressure safety switch is designed to shut the system off in case of fuel delivery issues before the system goes lean. A lean cust off switch is designed to shut the system off after the system has already went lean. So technically if the fuel pump were to fail the fpss would catch it before the system ever had a chance to go lean.

Now the lean cut off will be more precise in monituring airfuel as long as it is wired to a real wideband sensor. If it is wired to a narrow band sensor (stock 02 sensor) I would not even waist my time putting it on the car.

Bump?

Ray@Nitrous Outlet

I will look over it as soon as I can.....I need to get the Manufacturers suggested way to wire the Dynotune switch.

I appreciate it, thanks.

Any update?

Here are online instructions for the lean shut down switch.

So...according to this, I should run the A/F Lean Switch between the WOT Switch (Blue) and the 86 Port on the Relay (Yellow).

This leads to the problem of where to put the FPSS...can it be put in between the Timing Tuner and the 85 Port on the Relay?

I would still ditch the fpss. If you are dead set on running it put it between the lean shut down switch and the relay for the solenoid. Like inline on the white wire. To me that would be the most logical.

You're probably right, I have a Fuel Pressure gauge on my A-Pillar, so it's not like I'm not monitoring it anyway.

And if you have the lean shut down switch wired up to a wideband, then if you ever do loose fuel pressure and the system goes lean it will kill it fast.

Ray@Nitrous Outlet

I apologize for the delay in making this...I am not online every day...and do these in my spare time.



Thansk for you patience and understanding.

I did this one quickly so I apologize for the looks...I didn't have time to move stuff around to make it look better

No problem, it looks great and I can understand it.

One question though...would it be possible to switch the LSD and WOT in an attempt to save the wiring hassle of going from the activation button to the TB, back into the car to the LSD, and then back out of the car into the engine bay to the relay?

Ray@Nitrous Outlet

no problem...you can easily move the wot to either pin 85 or 86 on the relay

WS.666

iTrader: (28)

No no, I meant run the wiring like you have it but have it in this order:

Activation Button -> LSD -> WOT -> Relay

So you are going to put the red push button straight to the blue wire on the lsd, then put the wot switch inline with the yellow wire before the relay?

If so, you will be completing the circuit only when the system is armed, the button is pushed, the lsd is below the lean programmed afr, and the wot switch is activated.

This should work fine.
