Sometimes a bit more measurements are needed than usual.
The worst is the low-toothcount VR.
- With the 135 tooth audi it's only sectrig that's problematic (and we have very good recipe that works on factory systems and most tweakes systems as well).
- with subaru both the primary and secondary VR are the problematic low-toothcount VR: like MembersPage/SkassaSubaruNewtrigger
- this page was made after the shocking revelation of the extremely long (and therefore suspicious) MembersPage/SkassaSubaruNewtrigger where 30 deg gap > 90 deg !
Without finding out what is happening, there is little hope.
The following measurement is recommended, simultaneously
- soundcard record the input VR (divide by 10 to 100 should be fine)
- we want to see if the anomaly we've seen in the mde40 log can be seen in this as well
- we accept that the signal is possibly inverted (either both or none). For VR polarity, we have other measurements anyway.
- optional: scope record the output of the LM1815 (both channels)
- Manmde40 triggerlog (or with new nightly VT Tools/Triggerlog, save ) with 1.1.78 so we see the sectrig pulses too
Than start cranking. We'll syncronise the data if necessary. Take at least 8 seconds. (or 5+5 seconds)
Until this gets into the nightly VemsTune,
some executables are here: http://www.vems.hu/filethingie.php?subdir=pacsa
- for capturing mde40 log from Tools/Record-Analyze Triggerlog
- the scope version has realtime update
- still a bit crude, but much less keystrokes needed after any HW-change (sometimes just adjusting a potentiometer variable resistor) than earlier.
- unzip, and the exe (usually vemsTune-c.exe ) can be dropped into recent, installed nightly vemstune (and make sure to run the vemsTune-c of course).
