I also disabled LTFT and CL, i do my tuning in OL with STFT, except WOT and PE which require a wideband. I also disabled the MAF and set OL EQ to 1.0 after about 80 degrees, disabled DFCO and COT so there arent any fueling changes being made that you dont have control of. I removed most of your torque management settings so itll run better and probly spin the tires now lol. If it fires up and runs then let it warm up a couple of minutes and go get a good log, like 15-20 min of all types of driving, highway, in town, mid throttle, light throttle, off the line, acceleration while already going, ETC. Just dont get into PE or WOT! which i changed those settings so as long as you dont go past about 80% throttle you should be ok, and it really shouldnt come on even then. then apply that data to the VE table, make sure your lables on you histogram are the same as the lables in your VE table though. After applying the data to the VE DO NOT smooth the whole table. go through and interpolate any cells you did not get data for that are in between other cells of your data (see screenshot I used as an example) Be sure when using interpolate feature that the first and last cells you select are YOUR data, not something that was already there. Do these interpolations one at a time and not in big lumps and if there are any big transitions from one area to another then smooth that small area. Then go get more data and do this process a few times until your STFT is reading only about 1-2% error. Once youre happy with the VE then re enable MAF so it doesnt use VE and tune the MAF the same way. when that is done, then set dynamic air, MAF fail hertz, LTFT CL, PE, WOT, DFCO, and COT (IF YOU STILL HAVE CATS ONLY) back to factory and see how it runs. After all that is tuned then you can accurately tune the idle settings if you need to, however i alter a few of those as well, hopefully it fires right up and runs like a top. Let me know how it turns out, im off work til thursday night so ill be on here quite a bit if you need help.
P.S. do not forget to clear fuel trims in the special features of the scanner on the right side of the fuel tab, not the LTFT reset, before you log any data. if you do not then you will not get accurate data.
