Stim for Wheel Died? (FIXED)

Post by shaodome »

This is the same old V2 stim I've had for a long time now. It always used to work with "stim for wheel" but on the last few squirts i've built it does NOT any more. The tach signal gets to "TachSelect" but MS just doesn't pick it up.

I know the VR circuit is good as tested by a VR equipped disty. I'm wondering if Glen changed the U7 IC to something else?

Any input would be awesome.

This issue turned out to be that the pots were adjusted for a VR sensor, rather than the stim.

The spec on U7 on the v3 board changed a while back when the original part became unavailable, but the new one was tested by Lance and approved by Bruce.
