Cool article showing installing O2 sensors for each runner

 

Whoever does this, how long does the O2 sensor last?

 

Thank ou guys to post something interesting!!!

Looks to be SUB_C9F8 in 9563XXX6?

Was there another thread on ignition trim per cylinder somewhere?

General question, I assume it is setup to handle 6 cylinders in that sub?

 

Appears to be mentioned sporadically through the forum, most recently here:
https://www.evolutionm.net/forums/ec...ncrements.html

Mostly this thread by JCSBanks is referred to:

Then there's this thread on cylinder index:
https://www.evolutionm.net/forums/ec...dex-found.html

It seems to me that individual cylinder knock detection (logging) and control (active feedback and mapping) would be about the most useful new feature to the most number of users out here (everyone). Frankly I'd be stoked giving up resolution in the main maps to gain some course per cylinder 3d corrections. Think of all those duplicate rows and columns out there...

Consider how sensitive the tune is to timing, where often 1-2 deg makes a ton of difference in knock counts. Now think about how loose AF is run to run with the same settings, and how the car is relatively much more tolerant to these variations. If it's just one sensitive cylinder bringing you down a couple degrees, that could represent quite a bit of power.

It seems like just a bookkeeping task to note the active cylinder and write knock counts to an indexed table. [ME waving his SW hands in the air here]. Compared to a J&S box Mitsu has done all the windowing, load qualifying, thresholding, etc already. mrfred has mentioned a couple times it wouldn't be hard!

Token anecdotal J&S testing on a supercharged Ford. If you read the whole thread it sounds like they did some thorough testing:

I had seen a video that I can't seem to find now with John in the passenger seat of Stew's truck doing pulls. They were getting like -8deg consistently on one cylinder with much less randomly on some others.

 

Bumping this old thread. Just wondering if this has been figured out yet. Thanks.
