DIY exhaust emulator questions......

[gunut75]

I'm planning on making an exhaust emulator. Using the schematic in 150 links for Buell, etc, I had no problem getting the 10k resistor, but what does the "1K2" reference mean? 1.2K Ohms?
Also, the transistor, BC337. A listed substitute is the 2N4401. Will the 4401 work without issues? Thanks in advance.

Have you considered turning the option off with ECMSpy - it's permanent and you won't have to worry about the emulator failing and giving you a CEL (as they've been known to do).

I need to get busy and start practicing with EMC Spy. I would love to turn off that servo and check my maps out.
