[QUOTE="decipha, post: 15608173, member: 74327"] uhh no, there is no tp mapping, every time u turn the key on the ecu sets the lowest throttle voltage it sees to a relative throttle voltage of 0 this is called RATCH before you can dial in tip in fuel u need to dial in base fuel, get the fuel dialed so the fuel error is as near 0 as to u can get it then dial in inferred load / pct_load / totldst / LWFM table, whichever name your tuning software calls it tell your tuning pal to then set the max aircharge correction ARCANTCOR to 1.000 (note thats not the same scalar as ARCWOTCOR which is the wot correction) if that doesnt fix it, tell your tuner to start swinging the manifold volume scalar around, if its a lean tip in reduce, if rich increase if that doesnt do it, check the maf voltage on a tip in, it should be smooth and not jump around nor spike, if it does youll need to install a few screens on it to make it flow less turbulent all the info u will ever need to know can be found here [URL]http://www.efidynotuning.com[/URL] [/QUOTE]
