I wanna do some logs with the cable and bov and see if there is any negative side effects to 50/50 rec, full rec. and 100% atmos. venting blow off valves.
I'll save you the hassle. Every time you shift with a 100% atmospheric, the wideband goes to 9.2:1 and then back to where it's supposed to be in relation to throttle/boost..... Recirc takes the same plunge towards the rich side, but not as far. More like 10.2:1 or so, or so my bro's Innovate says.
And the 9.2:1 varies. I have gotten richer, and leaner. Pretty much stays in that area though. That's with a HKS SSQV on a 2003 WRX. WOTV's Map. <---KTHX----<<
