To correct my on self---Not 1/2 percent. Not real dumb just have AAAD. Age Activated Attention Disorder.
the ECM thru the O2 sensors, that are used from the factory, can be adjusted about 1/2 of a AFR number.
It can controll between 14.1-15-1. It is set at 14.6 and that is it's midpoint, but this is adjustable in the ECM.
The thing is, if yoy know the AFR at any time in the engine, then you can give those numbers to the ECM with the Tunners.
And to tell you something I have a SERT from Harley I would give away but it is locked to my ECM.
I replaced this with a TTS Mastertuner before the fix came in. Way much better. Lets you find out, using the O2 sensors, what the VE (volumetric efficency) is.
My bike is set where 95% of the time I am in closed loop. But with the TTS I know what the VE is outside closed loop and can give the engine what it needs when it ask for it. And be on the money.
Have been introduced all over again to this TTS becaused I but in a Woods TW400-6 over the Weekend.

Check out the TTS. Read up on it.
TTS people were the ones who designed the SERT, and apparently kept the design rights.
They then took The SERT and added to that program, which could already measure the O2 readings, and programed that to be able to give you the VE of each cilender with a sensor.
Simple whipout---
There is a extra tuning thing called the V-Tune. You take the program (Map) that you are using and on the AFR table put everything to 14.6. Program the ECM. Closed loop. Ride around a little and when you are thru you know exactly what the VE numbers are. Using that and some interpolation and you can be pretty close to what is really going on.
Then with those new numbers in the VE page of the Map put the AFR where you want.
The ECM used the VE tables to Calculate when outside 14.6, which is open loop.
If you have your SERT TTS will take it, they made it, and convert it to a TTS Module for a nominal sum. Last I heard about 100 Bucks.
