Wiring For Engine Harness
 

OK
I know this thread went a little off target but I need a little advice:
I'm going to try to get my stock 3.0 running on a stand to monitor pressures, idle speed and afr.
The frame is sorted out, as is the oil tank.
The starter will be activated using a remote starter switch.
The fuel pump will be operated separately with switched power too.

What do I do with the 14 pin connector?
Do I run a switched 12v to the +ve of the coil?
How will the WUR and AAR get their 12v or are they already supplied by the engine harness when it is connected to the starter motor/battery?

Any assistance appreciated.

Well, with a little help from a couple of guys here, it turned out it wasnt that hard at all.
Here's my engine running.

If anyone needs any help and I am able to provide, please don't hesitate to ask.

afr
 

Mike , they AFR is lean because the o2 sensor is not in the correct spot .
The way you have it mounted allows for ambient air to enter the o2 sensor .
The best fix is to weld the o2 bung just past the collector , or for a muffler style stick in you will have to make a shrouded system around the tip of the muffler and the sensor .
At the moment you are reading the mixing of fresh air with the exhaust.
My adjustable AFR sets the control pressure to any number you want , it is controlled by a knob in between the seats .
good luck

HI Ian
I'm interested in your adjustable WUR setup. How can I get more details, pricing, what's required etc.

Yes, I'm a little suspect of the sensor being so close to the exh. The Innovate clamp setup, I would have thought should be engineered to allow for the placement as such.

What do dyno tuners use to measure AFR on cars, that do not have built in WBO2?

^^^ Agree

You have to weld a bung between the collector and the muffler flange. The O2 sensor depends on heat, even a "heated sensor" is really only a "pre-heated sensor". The sensor needs something like 750F.
My testing shows an almost 200F difference between the collector and the muffler making the muffler itself not hot enough for a correct reading. The bung has to be welded into the header.

You can still make the O2 meter install temporary, they sell bung plugs.

BTW if you giggled at that....BAD DOG! :D
