I found a working TCR to use TC with this platinum wire: 0.01042. The number I kept finding was 0.00392 but that doesn't work when programmed into my RX200, most likely because that's the TCR for 100% pure platinum, and I'm using 95% platinum, which has a higher resistance. The TCR of 0.01042 I got off an engineering paper about thermocouples and the use of platinum in temperature sensor applications.



Using TC is greatly increasing the interval between coil cleanings; in straight power mode, I had to degunk the coils every other day. While this just meant pulling the wick, dry firing for 5 seconds, then rewicking, the longer I can stretch the interval between cleanings, the more the benefit of using platinum coils becomes evident in terms of saving time and maintenance, while also remaining the cleanest tasting wire I've come across.
