pulls timing with no knock at all
ive spoke to some people about this but dont understand how to tune around it, in the upper rpm ranges from like 6k on up i added timing in almost all the load cells, from 200 on up to 280, now the car will hit that timing(14 degrees) then pull about 3 degees out then about 300rpm later put it back in , there is no knock and the timing it goes to is no were on my map in any range at that rpms, it seems to do it every pull i make, i heard about the maf seeing to much air and pulling some timing but dont know how to tune around it, any advise? thank you
Mine does that from 3500 to 5000 rpm sometimes - flatening the adjacent load values helped a little.
There are other parameters (from MAF) that effect timing besides knock thight might be at play here

all adjacent load cell were smoothed, i even raised timing up more and smoothed out all load cells around it, it will still drop back to timing that is nowhere around the values i have set and have no knock
You are either over running the load columns or the ecu is seeing knock. I take it evoscan is reporting a knock count of 0? If so then you are overrunning the load columns most likely.

=5*513*(F217-0.435)/N217 is used to determine the load
it starts about 6700 rpm(id 242). Jumps from 14 to 11 to 14....
Unless its switching timing maps for one reason, I'm not sure why it's doing this.

This MAY be something to do with the ECU doing noise judgement routines. It may also be to do with boost/RPM limits for knock control as well - there is processing in the ECU related to both of the above.
On a separate note, there is a step enrichment at 7000 RPM on this ECU. AFRMAP and IPW go up together (one before the other which explains the blip in load at 7000 RPM down then up.... This is exactly like a lean spool disable feature on my ECU - I move it to 7500 RPM just before the 7606 rev limiter. I still think this sort of code may well be active on the US Evo IX as well as UK/JDM.

Will need to inspect US code for lean spool stuff then...
The range of noise judgement retard appears to be 1-3 degrees. 3 degrees retard on the log above, maybe it heard a noise and was testing to see if it was knock. Needs more work...

Ahhh, I see, well that looks kinda like the load flopping i have been seeing for some time now, looks kinda like it was jumping from one load cell to another on a diaganol. as in 6500, 260 load and 7000 240 load or something. Did you happen to log the maf reading? If it was maxed over 1600 it won't be of any use though.
So this happens even after reflashing?
If your map is asking to run an extreem amount of timing at unusual loads, it might pull timing before knock ever happens.
Could also be wiring or a problem with the MAF circuit that wont show up with logging.
One question, how did you log the load? Was it calculated by yourself from excel or did you get it to log like we did the OCT number

as discussed in another post im wondering if my conical style filter is affecting my load tables up so high in the rpm were i wouldnt expect the load to be and that is why it might be pulling some timing, the only column i have much lower timing is in the 300 load cells
