BMW M54B30 - Engine set up/injector phase

After a few hours on the dyno today we have been trying to explore the lack of throttle response from the engine which wasn’t there in V2 this is combined with some strange fueling issues as though the fuel isn’t being delivered at the correct time within the engine on throttle inputs, initially we thought possible in correct injection phase.

Below are some basics and screenshots from both V2 and V3. Hopefully you can have a look over and check.

Wiring - Coils and injectors are wired in numerical order - eg Cylinder 3 is wired to output 3 etc

V2 config - Had a similar issue when mapping on V2 and fixed by changing the offset to 5 as shown.

V3 config - We have experimented with injection angle control, both start of ignition event and end of injection hasn’t made a difference to the response.

I have commented in the main software thread regarding tuning the acceleration enrichment with a suggestion for a compensation table to possibly help with this too if the above appears correct.

Attached log - Approx 30 minutes into the log you can see various throttle inputs. Have had to compromise with the numbers for the acc enrichment as different amounts are needed depending on engine load.

Did you get this working?

correct firing order 1-5, 3-6, 2-4

I am still using the above settings, with the initial v3 bugs ironed out with the enrichment it works a lot better now. This dyno session was very early on in the v3 releases.

The firing order is as said above 1 5 3 6 2 4

I have the firing order offset as in v2 there was an offset setting.

Is anyone else has any other M54 configurations please share and I will compare and test.

Thanks
I notice we are using quite different primary trigger settings.
Mine are:
60
First trigger 45
Trigger angle 54 (set with timing light)

Will give your settings ago and see if it makes any difference.

Do you have a scope file of a running engine just to compare it?

here i made it today
and timing is checked with timing light

Looks similar but the base trigger settings different.
I have attached a scope and screen shot, let me know what you think.
