ah ic - I was not aware the J&S COULD function as timing device as well. Does it use an actual driver or is it piggybacking to the setup?

it actually uses an onboard MAP sensor to adjust the timing signal, it also allows for RPM based retard in increments of 2,4,6,8 degrees plus boost based retard...I think in all it will do 41-47 degrees of retard..

onboard MAP sensor would equal boost based retard

- neat feature, sort of like the MSD setup that came out years and years ago but this one seems more flexible and allows for more overall timing pull...neat safety margin

This unit is supposed to be DA Bomb..But I can not get miner to function properly..It operates on a waste spark system and when mine starts pulling timing it causes a misfire at 5800-6000 rpms like the rev limiter

John at J&Sw ants me to send it in for a reflash he thinks the DWELL needs to be adjusted..
