I have a fast wideband hooked up to my car and I have a speed density tune on the car. I have been tweaking on the ve table to try and make it right. I am only tuning part throttle right now. Problem is A/F ratio goes crazy. It goes from 14ish to 17ish. My buddy told me that on a big cammed car the A/F would not read right until after about 3k? So how do I know if its right or not? I heard you can tell by your STFTs, but I dont know what there supposed to read. I can post a tune or log if needed.
Thanks
