Amateur question; do oft tunes let the ecu hunt for knock by advancing ignition?

No they do not. Those sort of things are not done using a tune. Such a method involves a change in the algorithm inside the ECU

Here are some data logs of 3rd gear WOT after doing the BPB mod. I'm running 93 octane with the stage 2+ UEL map. I have a Perrin inlet tube, WORX drop in filter, Borla cat-back and headers. Hopefully, someone with more knowledge than me can tell me if everything looks ok. Thanks in advance.

there were a couple crazy spikes of flkc but it was at low rpm and partial throttle, not sure how serious that may be. it also seemed to take a while for the afr to lower as rpms increased. not an authority at interpreting all the numbers & implications but im interested to hear from someone more knowledgeable as well.

did you run a log prior to bpb to compare it against?

I didn't do any 3rd gear WOT pulls, but I have a 20 min log from my drive home from work the other day (pre-BPB mod). Not an apples to apples comparison, but might have some useful info.

I have read the tutorials. I am currently using V4.01 Stage2+ K00C Tune. What would the settings be if I use the power blocks on that tune? Provided if I used this tutorial?

It's been awhile since the original post and recommended tuning. Any changes that should be made?

There have been obvious changes to the standalone stage 1 and stage 2 for OFT OTS Tunes WITHOUT BPB.

One would guess that there should be changes to the OFT OTS tunes with BPB accordingly.

Would love to know thoughts on this. Its a week old and about 500 miles.

you have to remove ign timings from 5200 to redline because there is knock
afr looks good, but try to log "ltft"

[SnipeD]

Thanks, I think I took a degree out. This is after about a hundred miles. Any better?

So I'm looking to do similar modification of the v4 OFT tunes, specifically for the knock correction advance Max A map (as the other two are already all zeroes in this version). Leaning on the conservative side (?), I've made the following adjustments.

Being that these are mostly the same modified numbers as the v2.0XX instructions, I have a hard time thinking I'll blow up the engine, but any more informed opinions on the matter would be appreciated before I load it in

I just installed my BPB, my current tune is V4.0.3 Stage 2+. I have the same question as Hiko. Should I modify my "knock correction advance Max A" as Shiv's instruction back to 2014 or just leave it as original map with BPB?
Timing Compensation Per Cylinder A/B are both set to 0 in V4.0.3. Should have no concern in this part.

I did exactly that since the V4 was created, with no problem since

I'm an amateur here so take it easy on me.. I've got rom raider up and I'm looking at the "knock correction advance max A" and there is no difference in the files from Stage 1 through Stage 2+ (gas only no E85). Is that correct? Is this how aggressively the car adds timing? Should I just copy the 6000 row down as instructed in 2014?

Now for the "Timing compensation per cylinder" charts it looks like all of the charts are identical again. Should I just match what is recommended in the first chart by copying zeros across this entire chart?

As a side note, since this is pretty "simple" and the same for all cars it sounds like is there not an OFT tune that has this stuff already changed I could just go and grab for my car?
