Dsmlink logs after quick cruise and Pull Cel comes on under wot 10 degrees of knock

[Norcalgsx707]

So I just did a quick cruise and pull on my 1995 gsx Cel light comes on under wide open throttle if I take it off it goes away looks like knock goes up to 10 degrees during wot anyone want to help me tune this thing im sitting in it right now

Degrees is counts of knock.who tuned your car? Are you on stock injectors? How much boost you running? Do you have wideband? What's your air/fuel ratio under wot?

 

[Norcalgsx707]

I tuned it Im new to this I need help haha the air fuel ratio is deff running rich I think my afpr is running the normal 47 im running 680's all that info is in my profile, no wide band only dsm link, and my boost is running about 14 lbs just a guess old mbc hallman halfway down on a big 16g

First of all, are you sure your base ignition timing is properly set?

 

[Norcalgsx707]

I had everything dialed in at one time realy though Idk in the long log i posted it has my idle I did it the way the ecmlink site says to do it

I was out doing some pulls got the knock down by 2 but I cant see it going down anothe 7 thats crAYZEE and the more I tune the knock the more power seems to be lost

Okay its back up to 8 this is crazy Idk im starting to think my timing is screwed up

PTE/ Delphi 680's actually flow more like 640/650's.

Your CombFT's are sitting in the high 6% area at idle. Your Global Fuel trims need to drop to about the 30% ish mark and then refigure your dead times. This is compounding the fact that you ECU is thinking that it's flowing 680cc worth of fuel causing more than likely a lean condition... However, you can't really tell because you don't have a way to check without a WBO2. Do yourself a favor and get a wideband in there before you do any WOT tuning, that sort of feed back is essential to making accurate assessments in regards to your AFR's and deciding what course to take if you encounter knock.

New base tune still looks a little off

Actually, CombFT looks fairly good. If you're feeling picky you could add a little more deadtime in there to get it closer to zero... I'd relook at the MAFcomp adjustment due to changing the CombFT's and revert back to the stock timing tables, then watch for knock.

I feel like a jackass im guessing when I took off the positive to my battery a month ago to install my new system it reset everything hence giving me knock issues because it wasnt tuned well I dialed in the basic tune today And my knock issue is gone wondering if I should go ahead and grab a nice wot log now and try tunning some more
