Yeah... I can't see myself doing that... I might play around with the numbers a bit to see if I can improve idle.

there are links to a bunch of different injector specs here:
(scroll down to the calibration summary links)
the applicable specification to MS is "MINPW (ms)", for the 42# injectors it's 1.13ms.
I think you can also use the battery v/offset curve but I don't quite know how to translate it into something MS can use.

I just noticed your ignition input capture is set to "falling edge". Have you taken a composite & tooth log? It's almost certainly not right, and could account for 3 degrees of timing error. How is your VR input wired? it should be through VOUT (not VROUTINV), with rising edge, VR+ connected to the MS input and VR- connected to ground. you would only use falling edge if it was wired backwards, which you don't really want to do.
you also have "90" in "oddfire small angle" but you don't need anything there, we don't have oddfire V6's. :p
you need to disable "odd fire" in the basic/load menu, change it to even fire..Last edited by nando; 10-28-2010, 09:41 AM.

Nando,
Thanks for the info - that fixed my knock - I can't believe I missed that setting.
As for the rising edge vs falling edge on the crank sensor - I am wired through VROUTINV by Goathumpers instructions. If I change it to VROUT and change my input capture to rising edge, that would be the correct way?1988 325 auto-x car
