New mod, Kev?

BTW, does the Stillen kit come with a regular or Super FMU? If regular, wouldn't you be able to tune the A/F curve withOUT the need of the SAFC by upgrading to the SFMU?

Like Stillen would ever give out the better of two products that have the same function.

16 points, 8 for hi-throttle and 8 for lo-throttle. Per Keven97se, don't adjust the lo-throttle points because the ECU will relearn itself.

So you have 8 RPM points and you can do them in 500 RPM increments... so you can pick points like this:
1000
2000
3000
4000
5000
5500
6000
6500
which gives you 8 points.

Ok that makes sense. But I thought you have adjusted the low to like -29 or -40%. Or was that the High (the lowest point on high?) So when if the a/f is too rich at that level and you want to decrease it? do you just do everything on the high setting and leave low flat?

Not give out, but you may be able to "upgrade" if asked/paid for.

Regular FMU. Super FMU is $278.

With the SFMU, you can get only get a general a/f curve... meaning, if at 6000 you are 11.6:1 but the other points are 12.4:1, you can't do squat about it.

Nope, you're thinking about something else. There's a hi-throttle point and lo-throttle point you can adjust. Let's say I set lo-throttle to 30% and hi-throttle to 60% (the numbers are made up, don't use these). If your throttle percentage (basically, how much you mash the accelerator) is between 0 to 30%, the AFC will not do anything. From 30% to 60%, it will use the lo-throttle settings. If you mash the pedal hard enough and go over 60%, the AFC will use your hi-throttle settings.

To get around the ECU assimilating the adjusted a/f, 39% for lo-throttle and 40% for hi-throttle should be used, per Keven97se.

Yes, when a/f is rich, you want to decrease the number.

Yes, adjust the hi-throttle points and leave all the lo-throttle points at 0.
