The question is when you wire the LM-1 output to the ECU (7730) what pin do you land it on.

The EGO (O2 sensor) wire. I'm running my 89 MAF car that way right now (works fine, just remember to turn the meter on and off). It's strapped to the dyno as I type (trying to figure out a bug with our dyno's speed sensor cutting out at high speed). Also, take the analog ground (bare shield wire) and connect it into sensor ground (any sensor should work, such as TPS or MAP. Make sure you know which analog wire to use (red or white), or reprogram the LM1 to have the same output (use the setup that is .1 to .9 volts) on both wires - but use only one.

 

The text file with Mike Davis stuff says to go to "A3" on the 730, and "C18" on the 7727.
That would be TPS2 A/D channel 0, and the WB will display as "commanded AFR".
I wrote that down when I saw it.

Just re-quote, not my info.

Edit: That was for the DIY-WB, not the LM-1. Not sure if the tables are the same.

 

Oops, guess I didn't fully understand the question. I thought you just wanted to run your engine off the LM1, not datalogging it through some other channel. Hope it didn't cause you any grief.
