Meinhof's map, low idle.

[Grim]

Hi, thought I would give it another go, found the idle dropped to 1000 at 521mv with the air screws closed.

Anyone else using this map, is it ok just just set the idle where I want it (C1100) using the left idle stop screw and not worry about the MV going up?

..Cylinders are in sync at idle and 3k.

Thanks

While not using this map, I recall agreeing with @Meinolf that, once all the other parameters are set (TPS at 157mv, CO fuel trim at zero, valves set, and throttle bodies balanced), you can put the idle wherever you (and the motor) are happiest.

Personally, I prefer somewhere 1250-1350 which varies on its own under various conditions.

Here are a couple of Meinolf's posts where he confirms the "opening at idle is not critical" . . .

"The opening at idle is not critical. It will be what results out of setting the required idle speed with both cylinders synchronized carefully."

"The value after reconnecting the linkage doesn't have to be 525mV. It can be 500 or 400mV. The ECU will interpolate anyway (unless you follow below procedure, then your idle setting is exactly at a break point). Set it so the specific bike idles best."

[docc added the emphasis.]

This is my closing statement in Step 6) Idle Speed of the "Decent Tune-up" . . .

"Don't worry over the *degrees of opening* or the TPS idle voltage; seriously, just put the idle where the motor idles nicely for your conditions and liking. Once Steps 1-5 are set, you can put the idle anywhere you want. But you cannot start here."

The idle MV setting is a "guide only" not a specific requirement. It's only so you can set the idle screw to a start point after you've had the Butterflys fully closed to set the TPS and have a rough idle position to begin the tuning process.
