ECMlink Cant get rid of knock!!!

[94Jettameowpsst]

When there's "no power" but little to no knock its usually a bad knock sensor or o2 sensor. Whats the stats on your timing when it feels like theres nothing behing your right foot? And what are your o2 voltages at idle?

think i found my calprit....i have vertually gotten rid of knock bye doing a tune up and advancing timing on my dsmlink....my problem now is the car falling on its face in third gear up....im thinking its because my injecters are too small...my injecter duties are going over 90% and from what ive herd anything over 80 is pushing it....im not pulling timing when this happens...timing goes from 14 degrees and increases all the way to the red line...there is no low spots or dips in it..do you think my car falling on its face is from the injecters?,,,the only reason i dont know is because my a/f ratios are still ok...let me know what you think..and im sorry i have been trying to follow your advice illeagl.

If you can post some of your DSMlink logs. It will be alot easier to look at.

and i let off there....car was doing about 94mph....let me know what you guys think of this log

stupid computer didnt line them up right.

If you post the actual .dat file as an atttchment we can see what your settings are also.

That log doesn't look bad. Are your timing sliders zero'd out? I would probably pull a few degrees where its knocking. Also, is that the calculated A/F ratio or the wideband reading? Injector duties are getting up there but I still don't see why third is falling on its face. What rpm in third does it happen at.

 

[RacethisTSI]

no thats the calculated value by dsmlink...ill try advancing the timeing more...but do you see any reason that there would be a power loss in third?

 

[RacethisTSI]

wow ok guys...advanced timing alittle bit and the car runs beautiflly...thanks for eveyones help and ill keep you posted when i go to the dyno tommrow
