Where would I get a "wideband" o2 sensor? Can't find any, and would both need to be wideband sensors?

These have a data logger output.

Autometer and AEM also have wideband O2's, but I don't know that the price or quality is really any better.

The PCM just needs an NTK O2.

This is the one I have. It comes with its own O2 sensor.

 

The GlowShift also have the sensor, controller and harness... the same Bosch sensor I believe, and $59 less.

 

As for 24# injectors... I'm using a 23.7lbs/hr@49psi Bosch 4 Port injector (#0280155784).
That should be enough... Oh, it's an EV6, so I used an EV1-EV6 Adapter from Ford Racing (M-14464-A8).

 

My stocks clutch has held 500 ft/lbs for a long time.

 

Ok so the wideband o2 goes in separate from the PCM o2 sensors, before the cat correct?

Spillage, are you running a 408? And with the stock fuel pump? I was looking to the accel injectors from Hughes. 24s enough for the 408? I just wanna do it right the first time. I haven't done any performance builds with fuel injection yet. Would there be any benefits to running a 30 lb injector?

 

With injectors, going bigger isn't necessarily going to help you. They have a range that they are designed to operate in. The trick is, you want to be able to feed the engine enough fuel at WOT, and keep the injector at around 80% duty cycle or less. (this is where going bigger could help), but, the caveat here is, they need to be able to inject just enough fuel at slightly above minimum pulse width at idle, so you aren't running incredibly rich when idling. 30 lb injectors MIGHT be able to do that.... but, only way to find out is to test it.

Yep, wideband goes in separate, before the cat.

 

I went with 24# injectors because that's what the tuner recommended.


Mine is just a little on the rich side at WOT and a hair lean at idle and steady rpm driving.

 

If you plan on spraying nitrous I would venture a guess that you will need a pump with a larger cube engine especially if your pump has any age on it. I took the gamble with my Trans ams stock fuel system on a 150 shot. After the fuel it needed for motor we couldn't get enough fuel for a safe hit. Just my $.02

Edit: TA was stock cube with bolt ons and a cam, I wouldn't chance it on an engine I spent money on
