The injector scaling is quite off it seems. The PCM is doing all that it can to pull fuel to get you back on target (+/-32) is the most I have ever seen on the gauge. I went through this earlier this year.
When I first got my first map from AGP, the car ran but the trims where all jacked up like yours is now in the -32 range. Turns out that my map was scaled for RC 750's and not the DW 750's that I am running. There is quite a big difference between the two. I got a new map with different scaling and viola I was back within +/- 10.
damn thanks bor im gonna need to check that the wred think is that yesterday wen i was cheking my car i unplog my map sensor wen the car was on then i connect it turn the car on and my long trim star working fine wtf
thanks bro im gonna check with the guy that do my tune see if my rescale is for dw or rc

Did you load the tune then start the car cold? If so, it takes 170 degrees before the idle trim will start to adjust. This is why we tell all our customers to load tunes with the car warm. Seems pretty odd that the fuel trims adjusted after you messed with the sensor. Any idea what the sensor readings are? That might lead us to a different problem.
whats up john the car was warm like u told me and i log 3 minutes but the long trim stay at -32 so i dont know if thats the reason why im knocking at high rpms
IMO I wouldn't hammer on the car just yet with the fueltrims that messed up. I would wait until that was resolved before doing any WOT runs.
yeah man my car is knocking really bad but weird is just from 5500 till 7000 rpms is just spike from 0 knock till 6 knock at 5500 i dont know what to do i think im just gonna sell everything

Ah, don't give up so quick on it. If it is a tune someone made for you I am sure they will get you squared away. Get in touch with the tuner and give them a chance to correct it for you before you make the choice to give up.

I adjusted that for you last night and sent over another tune. This is the first time I had tried to adjust this part of your tune, so it should be better now. If I would have had a idle datalog to look at sooner... I would have adjusted it when I saw the issues with it.

I addressed this with the tune last night as well. I don't know why your ST knock counts are so high, but I dissabled them to see "if" this fixes it. Do not run the car WOT on this tune... you must datalog this tune to see if the knock goes away (one WOT pass). If it does then we know that there is a problem with the motor knocking or you have other issues that are causing the knock. How many miles do you have on your motor?

Older DW 750, which were just drilled out stockers, are a pita to scale. I'd avoid using them.
Whenever you have a maxed out LTFT and have a new tune to flash or Injector rescale, CLEAR fuel trims to 0 by disconnecting the battery. Thats gives the new tune a fresh start without having to fight against old jacked up fuel trims.

Problem being, we are tring to fix his tune that he got from another shop. We were addressing the knock and the knock only. It wasn't until last last week when I caught a quick shot of his idle fuel trims running at -32 . That is when I asked for a idle datalog.
What I am not understanding is the knock. No matter what timing change I make, or how much I change the knock sensor settings he is still getting the knock in ST that goes up to 5 or 6 counts. I am really starting to believe that he actually has knock in his new motor, which could be bad. I will be waiting for him to return another log to us (idle and 1 WOT pull) to verify if the problem is resolved.
