The spread sheet is based of the $51 VS tune. Let me re-work it to suit VT.Zero values
zero these values to ( I missed this in the first read)

n/a you won't get into this table at all, that is boost territory where you need a bigger MAF to be able to measure airflow that highSmall increase up here also ( maybe in vein as I dont know what a NA can really pull in MGC at WOT )
There is no point in modifying this table as it makes no difference when you are at WOT as the tune will operate in PE mode. That open loop table is really only used during cold starts and if there is a fault that forces the PCM out of closed loop mode (like a faulty O2 sensor).My Closed loop fuel ratio is unchanged at 14.76:1I have smothed the edges slightly as not to go from 14 to 13/12 in a cell ( heard big jumps were bad )

Does the transmission shift at the appropriate times or are you shifting it manually?What transmission do you run? diff ratio?
4L60E and standard rodeo read diff 4.55 from google (RA 2004 Rodeo Petrol originally)

- Im not logging data and dont know how (via pcm) I am however using a drag race app ( I had made) to log runs after changes to the tune. (to no good as nothing i change seems to make much appreciable difference)
I don't think a theoretical number based on displacement is relevant as there are so many variables that can alter the number. Ideally you need to run a datalog and then you can see exactly where in the map/tables the engine runs and adjust from there.[/quote]Can I confirm in the AFR/MGC/RPM that is indeed MGC of air? only one post I found says it matter of fact... then 3.8L/6 is .633L or 774mg of "air" approx so even WOT means 774mgc at best case.
* I have no idea what I am doing and just blundering through going down rabbit hole after rabbit hole. (somewhat frustrated)
If you are running stock injectors leave the calculation as is, there are a few different number listed on the web for 777 injectors and the data in the tune is correct.I will post pics of my tune but be gentle I have no idea.
Base rate injector comes standard at 361ms/gram the Kinjflow calc with the 777 injectors saying 26.35lb/hr say it should be 305msec/gram --( should I change this as 361 was probably set for a reason)
The stroke engine cycle requires 2 full rotations to complete one cycle so you really need to think of it as a 720° cycle (360° + 360°) so the 408° is correct but other then that I can't explain it much better, The1 who wrote the enhanced software can give more details, there is also more info in the PDF file.- End of injector target set to 408deg is that normal also? I have seen the cam profiles in the commodore books talk about 300ish deg but again unsure and rabbit holes scare me now.
[/quote]Photo explanation
My pea-brain assumes that the fuel map lets say on a hard static launch would go like in the image
WOT - High load therefore high MGC at say 1000RPM
Higher RPM less load as momentum is built
11seconds later bam let off 100kph or 660ft. (both splits recorded on my app)
