OMG am I reading this right?

This is not the stock evo 9 hi octane fuel map, right? This looks super-rich. This is the first read off of my ECU for me. I was looking around and reading the original nj1266 post on tuning and it looks like I'm driving a flame thrower.

Looks rich but actual AFR may differ, this tune seems done for a larger than stock turbo, if MAF and/or injectors are not properly scaled then a fuel map could look off as such. I suggest that you use a wideband to measure your actual AFR

^^^Definitely right! Just cuz it says that in the map doesn't mean much. Most times it's off a bit. Like foxbat said. Install a wideband O2 sensor and see what actual AFR is

I have a AEM Wideband (digital) and it's going on this week. So, you guys are saying is that this map could be off but it does have bearing on the AFR right?

It does have baring on the AFR. Check out the "how to tune an evo thread" there's a little talk about it in there. 9's and 10's could be 11's or maybe 12's it's in injector scaling and such.

Those values are not directly representing your actual AFR. Your gauge will give you a better representation.
