As of current, MS cannot do varied dwell time based on load or rpm. I have asked for that feature, but have not heard anything (but as said, it has voltage compensation). Im running 3.7ms and just took out another set of plugs in 1000 miles. Ive been running a .030 gap, and talking to my MS goto guy says I need to actually open the gap up to about .035. That the coil is so powerful a smaller gap actually acts like shorting the coil out. He runs a .040 gap on a 900whp car.
Im going to try iridiums this time tho, one heat range lower at an 8, over the copper 7's I have been running.
Guys on SupraForums were charging the coils to 5ms, but a lot of people were getting the coil break down and advancing there timing and taking motors out. IIRC, its been tested to 4.2ms
JDMFreak, do you want to sell 2 of them coils? Im putting together a 22re and have 2 left over from my set, just need to more. Im doing MS2 on that one.
