how much spark advance is everyone else seeing? i'm seeing up to 40-42 degrees and only seeing KR at very low rpms in between 1500-2200. but its very small about .2 of a degree no more then that.

.2 degree is nothing really, could be bumps in the road or other mods like motor mounts.

^^btw dude

i'm pretty sure you should see more than 15 degrees advance above 6400... if i remember correctly, my advance was around 24degrees at 6400 and kept increasing the higher my RPMs got

I'll check it out today when I get out of work (and if I can liberate the laptop from my roommate)

If he hasn't, he needs to remove the spark ramp out numbers (set them to 65535).

I still have no spark ramp out in my software I contacted HPT but they haven't gotten back to me as of yet. Still having my speed limiter is the only thing i'm actually disapointed with from the HPT software

Im still waiting for 2.1.11, I have modified my Advance up to the default 6500, after that it pulls timeing and I cant edit values. My advance is 24 though in the 6000s, I rose advance to 27 and got 1 KR between 6100 and 6500, that was running 93 octane, so for now Im keeping it at 24. Im also running leaner than stock.

i turned my vcm off to detecting any knock. i never budges off 0 doesnt even hit 0.2KR.....check out these tables what i did was set everything to 0 and i havent seen see KR ever since.

Spark control> Spark Retard> Knock Retard Attack (ECT gain)(BARO Gain)(Base Retard)
Spark Control> Spark Retard> Max Knock Retard> (vs RPM PE)(vs VAC NON-PE)

...BTW i'm running 87 octane

uh... i would turn your knock sensor back on if i were you

if you advance timing up top just a little too far, and you start to detonate, it doesn't take long to do damage... and even if you don't hurt it right now, you're weakening it for down the road

tune the car so you don't get KR... I'd accept up to 1 degree of retard sparatically.. if you get it constantly, thats different

don't turn you're knock sensor off you're going to regret it.. especially on 87 octane... <slaps head>

please just friggin put super in the car.. especially with your KR turned off... cuz now, not only are you running fuel thats prone to detonate, you turned off the vcm's only way to detect and counter detonation (retard ignition timing)

two bad moves dude... seriously

Wow, where did you get the idea to do that? I desensitized mine slightly, but I would NEVER recommend zeroing out that table.
