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.
