I applied the 58L TCI on my 31A bike and it runs flawless! It feels like I should have done this years earlier, but why should you, when it is not broken? For anyone in doubt to apply a 58L TCI on a 31A: Don’t hesitate! Thanks for your insights, Best regards, Martin Best regards,

I have a malfunctioning 31A TCI unit. The only affordable and available TCI is a 58L type. Is there any downside on using that newer TCI? Can it harm? I can't find any differences except this: HCP418 OEM TCI Ignitor Unit oem part # 31A-82305-10-00 small black label lettered: TYPE TID14-19 31A-10 (date code) 3 + 6 terminals Advance curve: 5* +/- 1* at 1050 rpms 7* at 1600 +/- 225 rpms 30* at 2900 +/- 300 rpms 33.5* +/- 2* at 3500 rpms 38.5* +/- 2* at 6000 rpms 39.5* +/- 2* at 6000 rpms 40* at 5500 rpms 36* at 9000 rpms Application: XJ900RK, RL HCP11857 OEM TCI Ignitor Unit oem part # 58L-82305-10-00 small yellow/golden label lettered: TYPE TID14-37 58L-10 (date code) Advance curve: unknown Application: XJ900 N, FN, F I hope someone can shine more light on this.
