Why is my engine retarding ignition?

[Zaffy_Boy]

Hi guys, please help me with my Zafira OPC Z20LEH.
Why is my engine retarding ignition?

I have always felt i was missing top end power so i logged my car with opcom (from ebay), and found out the ecu is retarding ignition.
This was on the EDS IPF 315ps map, i then uploaded the original map, and it is also retarding.

On 3 gear pull, knockcontrol becomes active at about 4300 rpm, 0,9 bar boost and retards ignition upto 12 degrees all the way to redline.
Outside temp was 4 degrees, inlet temp was max 27 degrees.
Car is running on Shell V-power 99 oct

My current setup:
Vectra C air intake pipe
Cdti airbox, KN filter
AET hybrid turbo
EDS front mountet intercooler
Custom powerpipe
EDS intake cam
EDS tophat
EDS turbo downpipe
Cobra 63mm sportskat
Milltek 63mm exhaust system
NGK iridium plugs (new)


Does anybody have any suggestions?

Thanx
Kasper from Denmark

knock control sensor ok?

 

[24-7]

Any DTC in ECU exisitng?
Fuel pump /fuel pressure.
Or check ignition coil module.

Any display for AFR in your car? can you log the lambda sensor?

Hi, i can see the knocksensor value in volts, in the opcom log.
It start at 4V and goes up to 65V along with the rpm.
I was going to change the knocksensor, but spoke to the main opel dealer, they have never sold one before!?
I dont want to spend money on parts if iam not sure they are broken.

I dont know what the normal knock value are, if anyone know, please tell me...

Hi there is no errorcodes present, if that what you mean by DTC.

I havent checked the fuel pressure, but i belive its a bit on the rich side.
Can it cause knock if its running to rich??

The log reads, on full load the lambda reads 840-930 mv.

How can i check the ignition coil module?
