The injectors were constantly swelling...we didn't go all out. The car was on the dyno for over two hours with Nigel doing partial-pulls. As soon as the a/f would display a value that wasn't where we wanted it to be he would let off the throttle.

I know you're not trying to be smart or an ass but it really does seem like you're trying to chalk up my injector failure on negligence. I can assure you that was not the case. On the last couple pulls that were done before cylinder three popped a/f readings were healthy right where we wanted them.

Just asked simple question. I trust Nigel. Thing is what if every time it went lean was bc that one cylinder. And adding fuel did nothing for that cylinder but only added extra fuel to the other 3 and adding so much at the AFr was rich with one cyl real lean.

If you read my post I said I was taking Nothing away from yall i just said mistakes happen.

What I mean is let's call 12.0 AFr 100% accurate fuel AFr.

If
1 was at 130%
2 was at 130%
3 was at 50%
4 was at 130%

(Again number are not scaled)

This would of giving you a rich overall AFr.

That's the correct way of thinking. It was making the other three rich to give us our targeted overall a/f reading that we were commanding.

Nice video. Looks like its pretty easy to set up and change.

That thing looks pretty versatile....I really like the graphic table it uses on the laptop....looks worth the investment.

Did you end up using your original o2 sensor and harness or did you rerun the new one?

[underSRTarmor]

Oh ya it's not the same hook up at the gauge. All new stuff went on car all old stuff came out.

The one thing that would've been cool to see is the gauge showing boost/vac and afrs simultaneously. Ah well, still awesome as it is.

What are you using to trigger the fail safe ?

Is a ground on or off

I'm gonna use ground off and use it on the ground side of the boost solenoid.

I just need to figure out what load the solenoid uses. I'm sure it's less than 1.5. That's all the gauge can do. If not ill have to use a relay.

The PC program does and shows rpm. All three at once.
