[QUOTE="Pro60modman, post: 15501261, member: 183885"] The Lasota manuals are very helpful. He goes into the step-by-step to set the car up for open or closed loop MAF tuning. I had a customer give me all his tuning gear after he gave up trying to tune his car and I read through his SCT manual. I could have spent $75 years ago and not gone through the days of BS figuring out SCT. The decipha guy who posted above also wrote some killer write ups that helped me a lot. Knowing what to adjust and what order is one thing but LaSota and Decipha's manuals fully explain the why. Fully understanding the Why saves you time solving problems and saves a LOT of frustration. Get your MAF transfer function perfect before getting into the other stuff. If you have the manual I would recommend using the open loop method, tuning the curve with the timing locked, get it really perfect, then go to method 2 using STFT and unlock the timing, put the base fuel table back the way it was, and turn on your closed loop. Log it all over again and readjust your MAF transfer. Make sure you have your open/closed loop switch parameters in your head and pay attention to your logs so you don't mistakenly adjust MAF to far up the function when STFT tuning. Glad your getting it all worked out! Tuning your own vehicle is always something to be proud of. Tuning is my absolute favorite thing to do. [/QUOTE]
