s60 pro main map tuning

Postby gsxr2mil » Sat Aug 01, 2020 8:47 pm

Hey I have 4 1000cc Injectors in my Hayabusa and I was wondering do you know about how much percent of fuel I have to take away to change or add to change the air fuel ratio by 1 point.... example im at 12.5 afr i want to go to 13.5 afr I subtract 3.5% etc. Seeing if it was a rule of thumb out here for changing the afr 1 point. Thanks

-6.8 % roughly by my reckoning . . . . . . . . but its not an exact science LOL!

7% at idle, will be very different than 7% at max load...

There is no rule.

Just change the numbers as necessary

Stevieturbo & thats exactly as I have seen it to, lower rpms etc require a way less change and up top at high load the change is much different

Now you're adding additional parameters to a simple question! The calculation will still be the same if the ratio's are maintained wherever in the map, whether correct running can be maintained is an altogether different question!
