Selective clutch %

[Addicted]

Hello Lance,

I've searched the docs but cannot find an explanation to why my 2 selective clutches show up on datalogs as a percentage?

I'm just starting to tune the shift and, for instance, the shift from 1 to 2 feels quite hard, I then checked the datalog to ensure that the selective clutch was actual operating during shifts. It is. However it varies between 25-65%. This isn't PWM'd output so I expected a digital response of 1 or 0

Martin,

Selective Clutch: Output is ON (PWM% from 12x1 table for spare port 1 and 2, from the 16x9 table for spare port 0) while shifting AND Clutch Output1 Pattern is ON for target gear, OFF otherwise.

This is here: http://www.msgpio.com/manuals/mshift/spareport.html, near the bottom.

This is saying that the PWM table is used whenever the output is on, so the controller reports the current PWM%. If you want an ON/OFF digital output, set the entire PWM% table to 100% (or 0% if your output is inverted and you have 100% as the off value, for example).

Lance.

Excellent! thanks Lance.

May I suggest that this:

If you want an ON/OFF digital output, set the entire PWM% table to 100%

Is added to the manual, just to hit us users across the face with it as I had read that section of the manual numerous times today I never realised it meant me, this is because in the 'spare port function' window one of the options is 'PWM Mode', but because I had selected 'Selective clutch' instead I didn't realise the PWM stuff was relevant to me. Does that make sense?

Thanks again.. (its all going well so far!!)

Good idea, it has been done.
