ss430....

ive been using 316l without a  whole lot of issues, generally using spaced coils; with the exception lf my crius. 

i just rceived some 438 from a  uddy of mine and for whatever reason is cant get them to stabilize adter theuve been at rest for a while.

ive tried 0.00138 amd 0.00170 S tcr values and 138 did seem to run gppd for the longest period of time;  but, does anyone have an idea on how o can make this work?
I have a spaced build an Aeolus v2 on a vapor shark -dual coil 0.14- 10wraos of 23g on a 3mm rod
I have a contact build on another setup that is identical contact coils.
