He logged MISC-->"RAW TPS1", but its 0V at all times. The one I always used is under Throttle Sensor Input--> "THR POSN"
You're right then, I'm wrong. Sorry that type of stuff is hard because I do Ford, Dodge and GM so it's always a big $hit-storm in my head when it comes to datalogging.
aight thanks for the help so far guys, i'm gonna reset the pcm and find the right stuff to log and get back with u guys. anything else about the log stands out to you guys?
aight went out and reset my battery so my fuel trims would reset. still getting that p0172 code, dont know if theres a fix for that yet. went out and bought new plugs and gapped them to .028 and still getting that big ass back fire. thought about trying 26 tomorrow. i saw someone on here awhile back saying they had to gap down to 24, i don't know if thats safe or good or not. anyways got another log with the correct stuff this time, feel free to chime in. by the way i am pulling max fuel from 5k to 7k and only seeing low to mid 11's in afr's and 26 timing max.
Are you sure you cleared the fuel trims??? They are nearly IDENTICAL to your first log. LTFT -33%
Also you said you are "pulling max fuel from 5k to 7k and only seeing low to mid 11's in afr's and 26 timing max."
but your Open loop FA(A/F) from 5K-7K is also unchanged at 8.929:1, between the 2 logs.
Also, the Injector Pulse Width is unbelievably high for 750cc,,This is just a hunch because I haven't seen any other good logs to compare to, but 28454us at 5700rpm seems huge.
Imo,,it looks as if you've never flashed the PCM

you know what you may be on to something, i had the same idea, boy if i have messed this up i'll feel so stupid. ok when i went to reset my pcm the first time i hooked the battery back up and started the car. it acted it like it did the first time when i put the 750's in with out a flash yet. stumbled real bad and had a crazy loop then smoothed out after about 30 seconds r so. so i said to myself maybe i should reset it agin but flash the tune before i start it next time. did the same thing, thought maybe this is what happens when u reset the battery. now on to your theory, did i even flash my pcm at all. when i sent my last written tune to mindmelt he told to click on GET TUNE FROM FILE and click no and download tune. ok did that and he sent it back to me the same morning. when i went to click on SEND TUNE TO FILE and upload the tune it wouldnt let me untill i backed up my original tune or something like that. this is where i think i might have messed up. but idk cause the file he sent me is in my handheld and in custom tune section. do u think i upload the file wrong somehow and put in my original backup instead?

I'm not familiar enough with moving files around to instruct you off the top of my head. Maybe some one can chime in.
I can say that flashing the PCM does take a minute or two and you do have to cycle the key on/off, twice i think. Once at the beginning and again at the end. At the end of flashing the Predator will ask you to unplug it or Reboot. Does this some familiar?
Your "Last TUNE Written" will also share the exact file name Mindmelt sent you.
