Alfa 2.0 V6 turbo

[lost]

Making progress.
now car idles at 850rpm , when i rev it to lets say 2000rpm and lift throttle, it dies.

Witch setting to look at to fix it?

[MWfire]

if you have bosch IAC, then put min pwm 37%
put to ref table 45%

Connected secondary trigger today, it works, im getting some trigger errors, maybe its becouse little loose sensor. (now fixed sensor mount+changer to falling edge trigger=no errors)
its hall from webshop, primary is 60-2 vr
alfa v6 fire order: 1,4,2,5,3,6

teeth order is set to: 20,40,60,80,100,0
COP's are paired on stepper output A B C like this:






Can someone take a look at the log/ config and suggest me injector fire order,injector spray angle and take a look at sec trigger settings. as guage jumps from 0 to 360degree sometimes.

Here is LOG:

If someone is so good to change it, you could mail me config to: [email protected]
THX!!

What problems do you have?
I`m not shure how does wasted spark works when you have secondary trigger,but i think your h[2] table is not ok.
It should be reversed (from bottom to top,as you can see in the dialog box)

If you wired cops like in picture then the outputs should look like:

A
C
B
A
C
B 

because youre firing order is  1-4-2-5-3-6

Thats how it works on VR 60-2 without Hall sensor....

it's (i posted wrong screenshot  :-[ )
And cops are connected like on posted picture
B
A
C
B
A
C

if i change it to
A
C
B
A
C
B

then it backfires

I dont understand what you want to know.
Isnt it starting?

On same VE , and same spark advance lambda fluctuates. 0,95-1,05 for example on idle. it seems like there is unburned fuel.
And when driving it it smells really bad from exhaust, fuel consumption is almost double than it should be.

Is your TS diode in place?
Sounds like injector control needs addressing, and quite possibly the injector sequence.
Best to inject at the same time as the cylinder is firing, the fuel then hits the back of a hot valve and evaporates nicely.

I had same problem at one cilinder when hot, .
Turn out to be a bad solder joint at cilinder one flyback diode path.
Sound like all injectors are to slow check flyback wire,
but first turn injector opening rampup to zero
with big injectors this can be to much fuel to stabelize.
This fuel is added to the calculated amount.
Check plugs, check ignition dwell if spark is not strong enough you get carbon build up and this gives a bad ignition to.

Resume:
Check voltage flyback and coils
Put rampup to zero
Dwell 4ms
Clean plug
Start engine
Still lots off fuel check accelleration enrichment
Carrefully recheck combined flyback
And for voltage pulldowns because off to much load on a wire
Goodluck

does anyone know why one of the three spark plugs on the front head is brown? :)
I also get missfire/backfire in intake on high load above 4000rpm

1-4-2-5-3-6  with camsync, it should be in sync now?
stepper B =1&5
stepper C =4&3
stepper A =2&6


angle curve is 400 is that ok?

trigger:






Why individual power 1 and 4 are always higher?

Any tips on Siemens injector 980cc HighZ settings. traditional / simplifed?

You can use the built-in report tool to publish triggerlog, config and log files. See the Help menu. It will produce a link that you can post here.

You may have your trigger sensor polarity reversed, that causes one cylinder pair to be a bit offset.

Here it is, triggerlog is included in "other" folder...

edit:
Just check injector connector with dvm in diode setting and got around 1800mV on all six.
On ec36 connector side,with injectors connected it was around 14.5ohm for all six of them.
