I ran the new 3D mapping today and it worked well. However, I did see Det on 10.0-10.5lbs with 3.5gallons of race today. I lowered the boost to 9lbs and it went away. I later went back and added fuel to 8300hi and 8500hi and ran 10lbs and it worked well and had no Det again. I still need some time on it, but it seemed good. It was very icy today so hard conditions to test in. Today is the first day I was able to turn it this high and not have Det. I will say that I have seen some Det issues before this program, mainly on long WOT pulls on the hill. It was periodic, but it did happen......so Inkedrider......there was some truth to what you said previously. While it did not happen all the time, and only happend under a load at WOT, it did happen. However, this new tune seems to be good, and possibly the real deal. One problem I am having is our fuel out here has Ethanol in it so I know that affects things. I am going to add a little more race fuel next time out and see how high I can turn the boost....probably 11-11.5. I am not sure how much the Ethanol affects things....if anyone can chime in on this I am all ears.
