7deg of knock retard
 

At WOT i was getting from 0.0 to about 2.0 but right when it shifted into 3rd it jumped to 6.9 degrees then back down.... Could vibrations cause false knock? Ever since i had my gears installed ive had alot of vibrations over 80.. and the 6.9 degrees of knock came in at 86mph.. I have an LT4 KM BTW

BTW Do all these other readings look ok?

MAP 99.3
AFGS 238.63
Fuel Trim Cell 15
Inj BPW Left 19.32
Inj BPW Right 19.29
Left O2 mV 941
Right O2 mV 932
TPS % 100
IAC Pos 51
IAC Tgt 32
Inj DC Left 71.2%
Inj DC Right 71.1%
TPS Volts 4.55

They look like mine

TPS 100%
TPS volts 4.56
Left O2 mv around 940
Right 02mv around 940
Fuel trim cell 15
Injectors pulse rate 17.40 - 18.90 milliseconds

Only thing I am curios about is the IAC
my scanner reports

learned idle position 22
Idle air Mtr position 22- 121 ***


*** in my intructions manual Idle air Mtr position say "the idle air motor is a throttle bypass that meters air during the idling of fuel injectec vehicles. the lower the number the lower the air flow. As loads are applied to the engine the reading will increase"

Thats exactly what I see in my logs... during WOT it goes from 22 all the way to 121 right before I end the Wot run. I have never take my Test WOTs beyond 70mph (I use and empty road).


I see on your post that your IAC positio is 51 but I dont see any numbers for IAC tgt.


My AFGS with everthing connected Stock is 228 grm/sec (restrictive OEM ducting)


so my readings are pretty much the same... my injectors pulse rate is less than yours but then my car is in-gesting less air so that makes sense.

my car currently is showing 0* knock retard with the MAF disconected and 3* knock retard with MAF connected.

At one point I did have upto 14* knock retard... since then I changed the MAP sensor because it was giving me some strange readings in the BARO at WOT. It was acurately measuring the engine vacum but I changed it anyways.

fixed the IAC tgt... still curious about my KR... Like to hear some others AFGS also... pretty interesting stuff

ive been getting 5-9 deg of retard with a lt4 km? i am clueless as well. i also have datamaster logs as well if anyone could take a look at them for me.
