yes I got that far but with just the middle connected it reads half of what it should be. ex. if the analog gauge and logworks shows 14:1 afr, smanager shows 7:1 afr in the sensor overlay with it changed to digital 0 as the sensor overlay.

just with the middle of the 2.5mm jack connected to IN- I get a reading in smanager but it's only half of what the analog gauge and logworks reads.

This is what I got so far...

2.5mm connector - S300 digital pin
tip - out
middle - in-
base - GND

configured like this I finally got a reading but it's showing 6:1 AFR in smanager while the analog gauge shows 13:1 AFR. I connected the serial out to my pc and confirmed that the values are the same ...

It's amazing that nobody knows exactly how to connect the lc-1 serial out to the s300 digital input...

I connected the Tx wire from the LC-1 Serial out connector to the S300 N- pin and the ground from the LC-1 serial out to the S300 ground pin. I do not get any reading. What am I missing?

I found a diagram of the LC-1 serial connector stating that the tip of the 2.5mm stereo plug was Tx, the next ...

Hmm... I think I can answer my own question...

I need to connect the serial out from the LC-1 to the Digital input on the S300 right?

so ground would go to GND on the s300, receive would go to the out pin on the s300, and transmit would go to the in+ pin.

if this is correct I need a 2.5mm jack ...

I just recently upgraded my S300 to the version 2. I had my LC-1 connected to D12 (EGR) on my P28 it worked fine. I want to connect the LC-1 to the digital input for datalogging. The help file only refers to connecting it to the "N" Pin, There is nothing labeled "N" in the digital pin area just gnd ...

I tried it out and the fuel pump does not prime and the CEL stays on. if I remove the wire I soldered on the fuel pump primes but of course the car wont start since the s300 does not have the correct fuel map programmed for my car. I can connect to the ECU with my laptop, the s300 manager says ...

I bought a used S300 for $80 shipped on a car forum. The reason for the price was there was a burnt trace on the S300 board. I figured it was a good deal IF i could get it to work. This is the Seller's story:

His friend was testing some sensors with the car running and grounded out a wire and the ...
