BenKey Posted September 26, 2006 Report Share Posted September 26, 2006 I've heard of people shifting @6900. Not on stock internals or tranny though. I shift at 6500 and I know 200 more rpms wouldn't be that big of a deal. Takes me out of my comfort zone though. Quote Link to comment Share on other sites More sharing options...

dounome Posted September 28, 2006 Author Report Share Posted September 28, 2006 (edited) Here is that damn log from the run that took my truck down. Ok maybe not anyone know how to post up a HPT log run on this site? Edited September 28, 2006 by dounome (see edit history) Quote Link to comment Share on other sites More sharing options...
zippy Posted September 28, 2006 Report Share Posted September 28, 2006 The easiest way is going to be to take a screenshot of it and post the picture. Quote Link to comment Share on other sites More sharing options...
dounome Posted September 28, 2006 Author Report Share Posted September 28, 2006 ah that sucks I was wanting to post the whole ten minute run and let the folks who use HPT see it. I will try the screen shot. Quote Link to comment Share on other sites More sharing options...
zippy Posted September 28, 2006 Report Share Posted September 28, 2006 You might be able to post it as an attatchment??? Never tried that with a regular file though. Quote Link to comment Share on other sites More sharing options...
TurbochargedBerserker Posted September 28, 2006 Report Share Posted September 28, 2006 (edited) Lucky # 7 why is that the cylinder that always seems to get toasted? <{POST_SNAPBACK}> Because of the manifold's tendancy to flow more air to #7 and being too close to the edge AFR wise.

SS_bnoon_SS Posted October 7, 2006 Report Share Posted October 7, 2006 Sorry about the slow response to posting your log file. I don't check my bnmotorsports.com email very often any more... Anyway, here's the log file http://www.bnmotorsports.com/20060606_Zipp...e3drivelog2.hpl Quote Link to comment Share on other sites More sharing options...
04CHASE Posted October 7, 2006 Report Share Posted October 7, 2006 where is the part where it went to 6700 rpms? can it read more than 8 degrees of kr?? that did happen very quiclkly . Quote Link to comment Share on other sites More sharing options...
SS_bnoon_SS Posted October 11, 2006 Report Share Posted October 11, 2006 (edited) The failure wasn't spark related at all from the looks of that scan as there wasn't one degree of KR until after he lifted the throttle, then it stayed steady until the end of the scan. From looking at that, something let go in the engine and broken bits of metal bouncing around is what is being read as steady KR until the end of the scan. If the KR had happened during 100% TPS somewhere, then yes, it would have been knock related, but not after letting off. Courisous as the the A/F ratio... Did you have a wideband? Do you have a config file to read/scan it in HPT? Edited October 11, 2006 by SS_bnoon_SS (see edit history) Quote Link to comment Share on other sites More sharing options...
zippy Posted October 11, 2006 Report Share Posted October 11, 2006 I also noticed the lack of KR* until after the throttle was lifted. What I did notice though is that when he went through first gear there just before the spot you just posted there is a dip in the maf and rpm as well as the O2 readings hit zero (not like a loss of communication, but a loss of fuel pressure). It almost appears that there was a fuel pressure loss in first gear and then it came back. If that was the case, that would be where the problem actually was, it just didn't break until the next kickdown. If it were just lean in the programming it should have had KR* the whole time also.
