Ben C34 Posted September 9, 2014 Share Posted September 9, 2014 Cheers for the explanation XKLABA. Ron, I can't see how when using the plug lead method you don't get an accurate reading. That's exactly how the timing guns are designed to work.

XKLABA Posted September 9, 2014 Share Posted September 9, 2014 Woot, on that flat smoky whitish face of the coil... Yeah, that bit, directly behind that whitish stuff is the part of the coil that makes the spark and the pick up in the light will pick up the coil firing Link to comment https://www.sau.com.au/forums/topic/446097-power-loss-on-downshifts-bouncing-idle-and-slight-hesitation-at-specific-rev-point-r34gtt/page/27/#findComment-7385845 Share on other sites More sharing options...

That's exactly how the timing guns are designed to work. This is right I just got lazy and didn't want to do that every time i set the timing after removing the Cas, adjusting the cam gear the replacing Cas set timing taking car for drive then repeat I think he meant the wire loop in the harness ?

rondofj Posted September 9, 2014 Author Share Posted September 9, 2014 OK just did what xklaba does - inductive pickup straight off no1 coil front face - 20-21 degrees on PFC commander AND harmonic balancer, so all good- this is the easiest n best method! Timings higher cos cars colder at 61 degrees water temp Link to comment https://www.sau.com.au/forums/topic/446097-power-loss-on-downshifts-bouncing-idle-and-slight-hesitation-at-specific-rev-point-r34gtt/page/27/#findComment-7385870 Share on other sites More sharing options...
rondofj Posted September 9, 2014 Author Share Posted September 9, 2014 (edited) The first time some weeks ago I didnt check the commander when setting cas to display 20 on harmonic balancer, I just assumed it would be 15 as thats what the idle always is on a hot engine, silly me didn't realize that on a slightly colder engine the commander would most likely have been displaying 20. And because 15 is the stock base timing that cemented the thought it WOULD be 15 displayed Edited September 9, 2014 by rondofj Link to comment https://www.sau.com.au/forums/topic/446097-power-loss-on-downshifts-bouncing-idle-and-slight-hesitation-at-specific-rev-point-r34gtt/page/27/#findComment-7385885 Share on other sites More sharing options...

rondofj Posted September 10, 2014 Author Share Posted September 10, 2014 Timings done n dusted. Fuel economy with new O2 sensor = 21l/100kms, same driving pattern as usual nothing new. Wideband with gauge on agenda, will that do on its own? Not wanting to get a datalogit etc, dont even have a laptop lolz but can borrow one. Option 2 is take to Unigroup n get an AFR log on dyno. Which is the better option?

rondofj Posted September 12, 2014 Author Share Posted September 12, 2014 Any other opinions on getting an afr log at the dyno vs getting own wideband with gauge?

rondofj Posted September 13, 2014 Author Share Posted September 13, 2014 Haha. Tuner will be seeing it soon. And what do u mean by actual fault Scotty? Fault of the temp power loss during shifts? Yep the bov entry could be the fault of that..but who cares..not worth fixing somethin that accounts for barely 2% of my driving. On a different note, see pics of my tacho/speedo combo in 5th, diff looks stock as far as I know and stock box of course. Something we spoke about once- pics to put it to rest.
