Is there any literature on concepts of tuning? I've always wanted to deepen my understanding of whats going on with my car.
I fixed it, I was basing my statement on fuel, not air, which is what the maf xfer table actually is. tis corrected now. however if you were using wideband readings you would definately use the 12.0/14.64 (again, theoretical numbers) and mult by that.
I still believe its increasing the fuel when your increasing airflow. I just got done tuning my gt500 which was running rich according to the wideband. I reduced airflow numbers and it leaned it out. When i tune i use stft for the bottom half of the maf curve and wideband readings for the top half 600+ counts (open loop)
Greg Banish has a few books you can pick up from amazon ($20 each) and an expensive CD (~$200). You can also get Don Lasota's book if you don't have it.
Maybe it is just me, but I trust the computer in closed loop (adaptive off) way more than I do a 200ish dollar wideband and I feel it is easier. Hate even relying on it in WOT, but I dont have thousands for a retarded expensive wideband.
this is correct in a sense. the base fuel tables will base their commands off of the maf xfer table. if you tell the car-hey, there's less air than you thought was coming through here- it'll put in less fuel etc. usually open loop occurs at 555 counts- did you change yours? (just wondering out of interest)
I found the banish stuff to be ok- but not great. I like the lasotta stuff cause it was more applicable to the prp software which I use.
If adaptive is off, closed loop isn't achieving anything really for you. plus with a wideband you can watch what's happening. an expensive wideband is not necessary at all. all it gives you is a reading- so as long as it's calibrated correctly, they're all the same. now bosch vs ntk sensor is a different argument for a different day.
