When injecting Nitrous, a wideband will more than likely read richer than it really is. Be careful. For some reason nitrous makes the AFR's appear to be rich when they are a little on the lean side of the numbers shown.

 

Good stuff!! Now you got me thinking about just throwing my kit on the Evo dang you!!

I'll see you in 2 weeks. We gotta get a geek out going. Can you say umm... GSC cams??

Cheers-

P.S. How is that Flash mod working for you? No stupid orange light since? or

 

Poor results...
hope it really was the fact that your bottle was empty causing the car to run ridiculously rich..

With my evo 7..totally stock w/ 3" exhaust,apexi safc, hks twin disc and a 75hp shot of NOS I went 11.7secs@118mph

So there is much much more room improvement for you. Keep in mind that mine was throttle activated and was hit from 1st-4th.

 

I've never seen this before. AFR is AFR. Most factory jet pairs makes the mixture run about 10.5:1. When running race fuel I normally run one jet smaller on the fuel side. This provides about a 11:1 ratio. Fat but safe. Added protection in the event one cylinder is leaner than the others.

 

I just took a Zex kit off of my car...Its for sale if anyone wants to buy it!

Worked great
