When i look at triggerlog it looks like its fireing 1-6-5-4-3-2 ignition, it shuld it be 1-4-2-5-3-6 like my engine real fire order is?

Hello Lost

When i look at triggerlog it looks like its fireing 1-6-5-4-3-2 ignition, it shuld it be 1-4-2-5-3-6 like my engine real fire order is?
Short answer: No.

Elaboration: The numbering in the triggerlog is after index (IGN0_Falling = Index 0) in the h[2] table (Ignition outputs, where you put the outputs in firing order and assign real cylinder number), internally the firmware uses sequential indexing (which is translated to actual cylinder number/output though the translation table h[2]).

Best regards, Dave

Thank you Dave for explainig.

I have checked with timing light cyl 5 and it alignes/strobes at the same time as cyl1, markings on engine and pulley aligns like when cyl1 is on TDC, i suppose its just one crankshaft rotation more, so its ok.
I counted and marked tooth  on pulley with paint and  cylinders 4-5-6 are exactly 120 degree apart (20 tooth), as i wrote before 1 aligns with 5. So it sould be 100% correct.

Does anyone know good dwell time for
vag vw cop 1.8t

06B905115R i think it has around 360ohm between pin 2 and 3 signal ground/signal+ on COP
I have them wired from ingnition outputs directly, one ignition output one cop, i have just added one 500ohm smd parralel to existing one on genboard.

Hello Lost,

Good to hear ignition timing is spot on now

Does anyone know good dwell time for
vag vw cop 1.8t 06B905115R
Good dwell for 115R VAG cops: 1.5-1.8ms,

Best regards, Dave

Could someone tell me inection angle curve to set in vemstune from this:


Engine is stock, has good idle, 14.7:1  but exhaust smell is terrible, really stinks, maybe injection angle would help or timing retard?
