1227808 ( AU Delco ) SPK:OUT:TIMLAG
Posted: Tue Dec 21, 2010 3:20 pm
Hi guys
I have a straight 6 engine running a factory Variable Reluctance Dizzy I have a Australian Camira HEI ignition module ( or chev V8 )
using a 1227808 Aussie ECM running kalmaker software
bottom left in this pic.
I have refrence angle set to 10 deg all is well all works well apart from the timing ( when viewed on a timing light ) sometimes go a little spastic ( like fixed at 20 deg as commanded by software and flickering to say 40 then back for a blink of the eye )
I was wondering how important this variable is
SPK:OUT:TIMLAG
Is the Kalmaker manual its regarded as distributor lag constant
V6 ( DIS ) , V8 DIzzy Hall effect, and 4 Cyl VR all use different refrence angles of course but also use different SPK:OUT:TIMLAG values.
The default camira lag may not match my dizzy as its not a 4 cyl camira dizzy
So my question is how important is this value ?
I was reading some book in relation to another make EFI system they state there timing lag variable ( that is fixed for a paticular dizzy/ crankfire setup )
must be setup correctly in the software ( to match your hardware ) or else your timing advance will not be correct over the entire rev range.
They say set the computer to say lock timing at 20 deg and with a timing light watch the timing as you go through the entire rev range in neutral.
If the timing varies or is not stable adjust the lag value until its correct..
anyone played with this before.
P.S
I believe I have the polarity of the VR sensor correct as if i invert it. It is very hard to keep running and if it does it cary's on and farts etc if I try and rev it.
The car revs cleanly to 6000rpm but I have always not been able to give it alot of timing and was wondering if its because this fantom just to 40 deg is causing some pinging and forcing me to lover the max advance.
the bottom line is my stock delco Australian Vn V6 commodore with factory everything Crank fire shows very stable timing on the timing light
I have tried 2 timing lights incase this is the problem.
P.P.S timing chain is new and back lash in dizzy to cam gear is also pretty sweet
