My bet is that you´ll get a number of different answers. So...here´s mine.
For the record i "map" engines for a living and have been part of developing the swedish stand alone EFI
For an NA engine i normaly shoot for an AFR of 12.7-12.8:1 for maximum torq and then a tad leaner,like 13.0-13.1:1,for maximum power.
(Supercharged engines of any sort is a VASTLY different animal)
It all can be dependant of fuel too. Around here sc E85 has been all the rage the past 10+yrs and alcohols in general...you get away with running a bit rich when on the wagon vs when using gasoline.
Economy in turn is MUCH harder as various different designs(combustion chambers especialy) burn a little different.
There´s those that claim that you will see no real benefit going beyond lambda 1. Ie-for gasoline 14.7:1 AFR.
On the other hand...companies like Nissan asf have been working on high stratosphere combchambers for quite some time to save fuel and have successfuly run down to 22:1.
I dunno...but for a bike...i at least think that going much past 14.7...what´s the point? It gets kind of detrimental as a bike in many ways is a recreational vehicle. More so even a sportsbike i guess.
Being one of those that do this for a living there´s a couple of pointers i´d like to ad.
First of all a dyno session of some sorts is an advantage. Not a neccesity if you know what you´re doing but it certainly helps and it certainly cuts down lead time.
Second of all the mainstay of mapping should be focused on idle,light load and coasting-out on the open road- as a fact is that for any vehicle using a number plate the mainstay of driving will be executed in that area.
To find out what happens at WOT...tbh..that is done rather quickly-all things compared.
Things like progression phases,vehicle dynamics aso aso however will affect how YOU drive and use the vehicle. Much more so than you might at first believe.
If you opt to use an EGT make sure you understand the physics involved in installing it. Then read up-intensly-how to interpret the info. EGT;s are a cause of much dispair as well as controverse....and the majority of hobbyist have no clue what the EGT REALLY tells and says.
If you can log the EGT with the rest of the info...that is a good thing.
Lastly loggin is your friend. You CAN NOT log to much.
