Genuine Digital TCI Unit (Ignition Module) for Royal Enfield Bullet 350 UCE / Classic 350 / Thunderbird 350 / Electra | 592238/B

If your Royal Enfield is facing no-spark, misfiring, sudden cut-off, hard starting, or erratic ignition, the Digital TCI Unit (592238/B) is a critical part to check. This is the OEM/Genuine Royal Enfield Digital TCI Unit used on select 350cc UCE-era and older carb/TCI-ignition models (not ECU/BS6 systems). It controls ignition timing and spark triggering—so a weak or failing unit can feel like a “fuel problem,” but the root cause is ignition control.

Unlike generic aftermarket ignition boxes that often cause inconsistent pickup timing and repeat failures, this part is intended to match the factory electrical behavior and restore reliable running. This listing is optimized to reduce wrong orders: please match your current unit/part number and model from the compatibility table before checkout.

Common references seen in the market include “Digital TCI Unit 570607 / 592238-B” depending on catalog format.

FAQs 

1) How do I confirm this is the correct TCI for my bike?
Check your existing unit for the printed part number / label. If your old unit references 592238/B (or 592238-B / 570607), this is the correct match. 

2) Will this fit Classic 350 Reborn / Meteor / Hunter / BS6 bikes?
No—those are ECU-controlled platforms and typically do not use this Digital TCI unit.

3) My bike is stalling and misfiring—does that mean the TCI is bad?
It’s a common cause, but not the only one. Rule out spark plug, ignition coil, pickup sensor, and wiring. If you have no spark or random cut-outs, TCI is a strong suspect.

4) Is this CDI or TCI?
This listing is for Digital TCI Unit (as named in catalog listings). 

5) Can I install it myself?
If you can access the stock unit and swap connectors securely, yes. Avoid pinched wiring and ensure couplers are fully locked.
