LED check engine light w a GM ECM/harness?

GM LSX swap experts step in please:

I'm going to check it out tomorrow, but I was told not to run an LED check engine light with an LED. Seems the LED has no resistance and therefore the computer thinks it's out and goes nuts (limp mode).

Ever heard of this? The fix is to wire up a light bulb.
