I wanted to give a follow up since the last time I posted my PL data. If you are unfamiliar with my last post, I was having a bucking/stuttering issue at WOT during the only pull I made that night, which was 23psi. That spiked to nearly 32psi and I was looking for answers regarding the detonation I was getting up top and the bucking.
This time around as the title mentioned, I have installed an LS1 MAF sensor along with a MAF-T to replace the OEM MAF I had on the last time. I set the MAF-T to run 10% lean at idle and in hopes of doing away with the knock, I increased fuel at WOT 6%.
I am still getting a knock alert from my ATR box that beeps angrily when I accelerate, but it is only during hard acceleration on the way up. After I reach around 4k, it goes away. I searched through other posts on here and other boards and others who had this issue felt that it was a false reading. If this is the case, I would like to somehow get the car to ignore this false reading without actually setting my knock retard to 0.1 degrees. Any ideas?
Also, I don't have an aftermarket wideband installed yet, so the AFR you see is electrical.
Also, disclaimer, I have an audible exhaust leak which may be throwing things off a bit, so take that into consideration. I also only pulled to about 4900rpm duee to being on a public road.
First pull @ approx. 14.5psi (file titled low boost pull)
Second pull @ 18.5psi (file titled high boost pull)
Both pulls felt relatively smooth, but the higher boost felt more linear and natural. let me know what adjustments I could make to improve.
