Some EFIlive runs ???? about timing and KR I did a 30 min run with EFIlive and got @ 1,900 data points collected and I am trying to get my LTFTs down and I have pretty much accomplished this but have some other data that I am unsure about. Basically I have MAC headers and a VIG3200 for major mods with Stock MAF. First off I know the 01-02s have less timing at WOT but does my timing data look correct. Below are summary numbers collected.
Ignition Timing Advance Data running 94 OCTANE gas
--------------------------------------
Datapoints Under Load 1,236
Datapoints Under WOT 690
Average Load Timing 27.3
Average WOT Timing 19.4...... This car has not be adjusted or played with a lot, this is pretty much what it looked like last year stock.
Below is the ignition timing with KR hits in RPM range with 690 WOT data points collected.
RPM..........3600-4000.......4000-4400......4400-4800.......4800-5200
Data points......14...................48............... .210...................209
Timing............17.8................18.8........ .....18.7..................18.5
KR events.........2....................17............ ...30.....................118
AVG KR...........1.7.....................1.2.......... ....1.5..................1.6 with 20 hits at over 3
KR drops right off after 5200 RPM. Also when I look at the data points the KR between 4800-5200 is not in each data point. One point will have 0.5 and the next point will have .01 and then 3.1 and then 1.8 and then nothing for a few data points and then it cycles like that all over again but no back to back data points with large KR ????????? Could this be the KR sensors?????
Also my O2 avg at WOT is b1 .897 & b2 .895 with 20 KR hits above 3 out off 690 WOT data points with the highest being 3.69 fuel looks good but the KR has me baffled.... I really don't want to add fuel as I don't see this as my issue and the low timing certainly doesn't look like the issue.
I have the CSV file if any one would like to take a peek but it is a 1 MEG in size
