WOT knock and lean

[phantom_19]

Hi

I have a 1993 awd talon with a good ECU, 2G maf,880cc and a FPR 255 wally.
Today I did a 3rd gear pull up to about 6K because I was scared of going further. I knock about 7-9 degrees at 4-6K. I am really scared. My base timing is correct at 5 degrees at idle.

Can anyone look at my log and see what needs to be done? I also have a WBlog.

Looks to me you need to start adding fuel at 3.5k all the way to 6k and beyond.

I noticed that the boost keeps rising after 4.5K. I have a autometer gauge and it shows 12 psi from 3K till 4.5K then rises to almost 18 psi. It should be constant right?
I have the WG from my big 16G mhi hooked up to a nipple on the throttle body

I did add some fuel in the fuel tab, only about 6% max. When I checked it just got leaner by a min of 0.2 on each rpm row

The boost is likely creeping because that turbo cant flow enough exhaust out the wastegate to hold boost that low, and also, the line youve got from the wastegate to the tb is way too long, causing delayed response. You really want this line as short as possible, and ideally, as close to the compressor cover as possible. You can weld a 1/8" NPT bung to the j- pipe, screw in a 1/8" npt nipple for a 3/16" hose, then hook that to the wastegate if you dont have a boost controller- this is the proper way to do this, but the boost will still increase with RPM, so if youve got a FMIC, just get the AFR at WOT in check and the timing advance, and shoot for 20psi boost with a boost controller and itll hold better.
The following is copied and pasted from your log. In this area, you are way too lean (unless youre running E85, then its still too lean) and theres too much timing advance in this area as well. If this is on 93 pump, dont even go WOT until youve got the lean condition under control or youre going to melt something. Hows your maf comp? Do you have it so that boost est is on par with the boost youre running? Make sure your global setting for the injectors is correct for the manufacturer's injectors, not just the advertised size, and set the deadtime the same way, make sure your base fuel pressure is correct. Then, play with the fuel and timing maps on the DA tables. If youre on pump, start out with 10.5:1 in the load cells youre hitting at wot, if your maf comp and injector settings are close, the wideband will read at near what youve set your cells to. Why not just download the EVO timing map from the ECMLINK site and tune from there? The EVO timing map, or even a 2G timing map would be a good start and should eliminate knock due to too much timing.
