[QUOTE="01yellercobra, post: 16692207, member: 35549"] [USER=8854]@MalcolmV8[/USER] I'd have to check my settings and get back to you. I'm actually running one sensor on the driver side. I wanted to run dual, but had issues trying to get the plugs out the ECU and got frustrated. I'm using a Bosch wideband sensor for the 3V 4.6. For the knock in I made a few WOT with low timing and E85 to see where it usually was. It hangs around 2.5 even at part throttle. I figure most of it is the exhaust at that point. I did some testing where I set the knock in below the threshold I was seeing and everytime crossed the threshold it pulled timing like I commanded. After that I had one instance where my tune went wonky and somehow my VE went lean at WOT. It was a short hit when I saw it, but looking at the log the knock sensor kicked in and pulled timing like it was supposed to. Is it perfect? Probably not. But I do feel better having it. The car does spend most of its time on E85 now though. And the pump gas side of things is extremely conservative. [/QUOTE]
