Default Check your LC-1 defaults

Just a heads up:

Innovative's documentation shows that the LC-1 should be pnp out of the box, assuming gasoline engine, 0-1 NB on analog 1 and 0-5v out on analog 2. So if installed correctly, the default programming is to send data to an XD-16 gauge via the serial out, simulate nb via a1, and send data to a logger on a2.
Initially, my lc/xd showed false afrs around 5:1, caused stubling and poor acceleration, and a CEL.

Installation: wb sensor in standard Greddy dp location, LC-1 sending data to XD-16 gauge and simulating NB to ecu
Symptoms: Display showing 5:1 afr, 5k rpm stuble, CEL, poor acceleration
Problem 1: default AFR multiplier set to a random value
Problem 2: default analog out 1 values set to 0V at 14:1 and 1V at 15:1
Solution: Correct values with LM Programmer
Lesson: Always check default settings

Because of this, I would not recommend this "stand alone" system to anyone who does not own or have access to a laptop.
