Knockevents
Has anybody ever had some real knockevents showing on Datalogit of you Apexi Power FC?
It seems as my engine knocked yesterday, but the numbers in the log look perfectly the same as on some more runs, same gear same ignitionadvance and same AFR!
Here is the short log.
InjDuty/Ign/AirFlow/RPM/Speed/Boost/Knk/WtrT/AirT/AFR
44.0 32 4010 4598 72 79 3 83 28 12.079
49.0 27 4135 4716 74 84 2 83 28 11.580

85.0 28 4780 6918 105 172 7 83 28 11.272
84.0 28 4775 7035 107 171 8 83 28 11.374
44.0 29 4710 7109 109 170 6 83 28 11.402
Had the same gear and all parameters on a second run and no knock at all!
On the second run watertemp was 88°C and Airtemp 30°C, so even higher temps! Ignition and AFR are totally the same, but knock is only at 8, where you see 55 in the log above!
The TXS Knocklite did not show any knock as well...
Can anyone explain this phenomenon?
Many thanks for your inputs!
