OK it's that time of year and I have a questions but first of all some explanation.
I am using twintec 2 and taking lot's of samples. I am playing around with sample time, filter and number of samples and I think getting the hang of things.
I have made some suggested changes to the rear and front VE tables on the 2002 to 2004 base map (SE mufflers and K&N) I loaded as a starting point for my 2003 VRSCA HDI model completely stock except I have gone topless and bottomless and have fitted a K&N air filter.
I join the club and prefer to set a 13.2 AFR instead of leaving in the AFR from the starting cal and using the command as target as from my point of view I look at the AFR recorded and if I know the command is 13.2 it's easy to see any differences. I know you can select % change but I still like to see the differences between what I measured and what I requested.
OK the reason for this post.
Assuming my VE tables are dialled in if I select colour regions view in mastertune I see a table with the various colours. I can also select 3D graph which is the same but in 3D. So if I put the AFR table back in to my working calibration (from my starting calibration) then select the Spark advance tables I believe I may be able to see some relationships if I print the various table out in colour.
I am now looking at the printout of the AFR for the starting calibration and comparing this to the colour printouts of the starting calibration for the front and rear VE and the starting calibration spark tables.
My thought is that I should see some correlation so that when I print out the colour front and rear VE for my working calibration I should be able to adjust the starting calibration AFR to suit where my peak torque is and use that for my working calibration. Moving on from that if I can see a correlation in the spark advance then I will also change that in my working calibration to suit my VE's and new AFR.
Am I completely off base here or going in the right direction? I hope you can understand my question.
