Assembling a MS II w/V3.0
Have VR sensor & MSD 6A ignition
V3.0 assembly Guide step 65 note: says if using a high current driver circuit, you likely need to add a pull-up resistor.
DIYAutoTune.com/tech_articles_common MegaSquirt modifications_adding pull up resistor, says VR sensors always put out an AC signal and do not need this mod.
Any suggestions?

I was under the impression that you use the high current driver circuit if you intend to drive a coil straight from the MS itself (relegging the need for an ignitor like the MSD 6A).

How many tooth VR does your engine have?

And what engine is it for?

Neither one of these calls fora pull up resistor.

Thank You
