efi megasquirt VR sensor help

[highboostin2K2]

To mount my VR sensor, the EDIS 36-1 wheel I have is mounted on the pulley kind of backwards, it's mounted 90 degrees AFTER TDC not before it, so where would I want to mount the sensor - I can set piston 1 at TDC but where would the VR sensor go in relation to the gap in the wheel?

at top dead center the the vr sensor should be 9 teeth (90*) ahead of the missing tooth. if your not able to get it in that posision you can always set a trigger offset in megatune

No problem at all. I have the same problem. I mounted my toothed wheel 180 degrees offset, just like you. Just switch the coils, or switch the leads from the EDIS to the coils.

It's a wasted spark system. Each coil fires a spark every rotation of the crank, and each coil is 180 deg offset from each other. So you either need to swap the coils, or fool the coils into thinking the first is the second and vice versa.

email me if you want me to talk you through it.
