What kind of timing are you commanding/ getting?

stock timing. Just scanned again and it is 3-4 and it spikes 11 right before the 2nd gear shift and goes back to 3
11-03-2009
just scanned a final time 0-75mph run, 0 kr !! This is what i wanted to see. Im gonna get a tune next and scan again.
11-03-2009
From 11* to 0* Amazing! lol How much timing with the last run with 0 KR?
11-03-2009
I am surprized you only have 11*. Depending on how you got on the abuse mods could work different and give you different levels of kr.
11-03-2009
spark advance on the last run was 34 degrees. 01gtp, i have no knock now
11-04-2009
may sound stupid but just trying to help. Could it be false knock?
11-04-2009
i had 10* when i started tuning my car. not too bad for that much done and you not doing a stitch of tuning.
11-04-2009
Well like i said it has no knock now, dont know what was going on.
11-04-2009
Bad gas me thinks
11-04-2009
different weather, different this different that.. you still have 11 degrees.
Time to tune or kill the motor. It's a matter of time and choices.
11-04-2009
Yeah...I was going to say weather...changes A LOT of things with boosted cars.
11-04-2009
Well it was scanned a couple times, 0 kr. I think what was happening was i was looking at the wrong kr. Under steady full throttle its 0 and when i let off right at 75 it spiked for a second then went down, but thats off the throttle.
11-04-2009
Like Oh4CompG said bad gas. What octane are u running?
11-04-2009
93 octane. All runs were made within 10 minutes of each other, no changes. Like i said before, it was spike knock after i had let off the throttle. It was a misunderstanding and looking at it closer and on the time line on the scanner it revealed no knock on acceleration. (using a Snap-On Ethos scanner)
11-04-2009
so now the question is, how do you have 0* knock on a stock tune?
11-04-2009
i find it very hard to belive your not going to knock with the stock tune. my car does and im still on the stock pulley. your on a 3.4 with higher compession and no tuning. these cars knock in stock form. something seems a little off.
11-04-2009
i have lots of flow mods look at my sig. I get a max of 7 psi on the 3.4. The scanner doesnt lie.
