2jz vvti stock engine ignition drift question.

[Vidar]

Have a 2jz vvti with link fury g4+

Audi r8 coils

Link 1000cc injectors

Have det trigger setup as 1jz vvti,

Also cam control as 2jz vvti.

36-2 crank trigger and 3 cam trigger.

Offset main 199. Cam offset 171.

When i lock ignition it drift 10-15degress. When vvti activates.

Before and after vvti activation ignition is dead on. Checked with digital ign lamp.

Vvti table is set 5degress 2000rpm, 30 on 2500, 20 on 3000 and 5 on 3500. Rest is zero. When vvti is zero i have no ignition drift. 

Was checked after i had to retract ignition 12 degress with vvti aktive because of knock.

Can you give us a trigger scope with cam at zero and another with the cam advanced enough to cause the timing change.

The crank sensor is wired incorrect polarity, swap the +/- wires on it and your drift should be fixed.  The cam sensor is ok as is.

Thank you very much. I didnt see that myself.
