Frequently Asked Questions

Can I use this while the engine is running?

Yes — the breakout box allows you to measure input and output signals with the engine running without shutting down the EFI module.

Do I need to disconnect anything permanently to use this?

No. The box inserts between the EFI module and wiring harness, then removes cleanly. Your bike continues to run normally while connected.

Will this work on my fuel-injected Harley or Indian?

If your bike has a 62-pin EFI connector, yes. Confirm your EFI module connector matches this pin count before ordering.

What tools do I need to install it?

Basic hand tools to access the EFI module connector. The breakout box plugs in — no soldering or cutting required.
