turbo c5 wot knock
turbo c5 wot knock 2001 c5 LQ4 iron block 10:1 with 317 heads, 234-236@.50 .612 .612 lift 115 lsa, ngk-7 gapped at 28, new msd wires, 102 tb 102 intake m-10 water injection nozzle coming on at 7 psi full at 10psi, precission billet 76 turbo air to air intercooler.
Ok so I have a knock issue at 4k, yesterday I thought I fixed it after doing some tuning but today on the way to work it came back. Yesterday I did 3 logs and all showed 0 counts of knock today I had 2 counts on my way to work(laptop died and lost that 0 knock log) so I logged timing on the way home today to see if I could notice anything unusual and I didn't see anything. It knocks every time starting at 4k I am sure it is in the tune I am just over looking something. I have tried it with and without the water injection makes no difference, I have tested the meth system and it does work. I have also raised the timing as far as 16 and have gone as low as 8 afr wot I have tried 10.5 to 11.5.
