iv got a few tuning questions
iv got a few tuning questions im using tunercats
im curious what my knock settings should be at to eliminate false knock. as soon as i open my cutouts, my knock sensor goes nuts.
my extended spark table says i should be at 32 degrees advanced at wot. datalogger says its at 36 degrees. i cant find out where the other 4 degrees is comming from

ElkySS - go to your Max knock retard vs. RPM (in PE) table and make sure anything above 4K is set to 0. Then go to your Max KR vs. MAP (not in PE) and set all tables (MAP reading where you are picking up knock - from your log) to 0. Lastly, go to your Burst Knock Retard vs. Coolant Temp and change all cells from -40-68 deg to 0. That should cover you and I'd recc. getting a LT4 km to help out with that false knock. You know how to reach me so call me if you need any help or have any questions.

Probably from countless tuning threads where people were trying to find timing advance that was seemingly unaccounted for by known tables. Why are you jumping on the guy when this question has been around for a long time?
Shbox - I highly doubt there is a hidden table in there somewhere. If so why has it never been shown or proven and the LT1 has been out for almost 20 years now?

Verdad Gallardo im not seeing any knock at all at wot with the cutouts closed but im only at 36 degrees. havent tried it with them open yet. im seeing random small retard. like less than a degree in most places. the biggest knock i see is in a high gear, low rpm when i hit the gas.

I'm just saying that there is some advance that no one have been able to find where it comes from. Those discussions have been around for years. 
I would make a track tune for your car and just set all the Kock tables to zero like stated. load it up and make a run, see what happens.
Cut outs are for the track, your good with them closed and on the street so that would be my soloution. Or just limit what can be puledl. Max it out to like 2?

what if i used the knock sensor to add timing with the cutouts closed. then when i hit knock, back it off 2 degrees and then disable the knock sensor under wot.
Have you ever even tuned or tweaked on a tune for the LT1? Where the heck did you get that bit of wonderful information?
