So I have decided to go for the Stock HALL trigger in the HEI distributor.
I have a V3.3 genboard, What do i have to change?
So I have to reconfigure My hardware from Primary VR to Primary HALL..
- I got hold of this site but my circut board doesn't look like the same
- but don't worry, SJ2 and SJ6 (that you care about) are the same
- R30 pullup that is missing or weak (22k or higher) with VR, should be strong (1k .. 22k) with HALL (but external pullup is also possible, of course, the effective value counts )
This is what i did..
SJ2 changed from open to closed
SJ6 changed from closed to open
R30 2.2k resistor (just took one thats bigger than 2k)
R56 18k keept because R30 is 4k7 or lower.
- measure DC voltage between SJ2 and GND (with board powered, but HALL sensor not connected or inactive): must be higher than 3V
