As the title says.... The evoscan display does not match my LC-1 DB gauge. My logs show .2 to .3 leaner vs the gauge at all RPMs and loads. Is it safe for me to assume that the serial output is a more correct number vs the guage?

 

Does the DB gauge work off the LC-1 analogue voltage output?

edit:

Answered my own question using the POWAH OF GOOGLE. Yes, it is analogue only. So you're not comparing "gauge to EvoScan" - you're comparing LC-1 "analogue to serial". And your analogue output relies on all that fun grounding stuff to be accurate. My guess is that your voltage reading is offset by a fixed amount. The serial reading will be the accurate one.

Try rejigging your DB wiring, eg. the earth connection - see if a different location gets you closer to the EvoScan display.

I actually ordered an Inno DB gauge. Right after I hit "buy", I noticed the "analog only" text, and pestered Innovate to change my order to a (much more expensive) XD-16... which works off the serial data connection. The funky tri-colour reprogrammable LEDs had nothing to do with my decision. Ahem.

Logworks will display the actual AFR serially

 

Not to a gauge on the dash though.

 

well, i was think that i would rather rely on my logs for tuning(serial output) and use the guage as the day to day monitor.

 

Say, why not just use Inno's LM Programmer utility to adjust the LC-1 analogue output voltage by a hair?

Just tell the LC-1 to send a slightly higher voltage across the entire range, ie. shift the graph line up a wee bit.

Tweak it so that your gauge and serial are exactly in line. Then you can be 100% confident in your day-to-day monitoring.
