Hello, I have a Teensy 4.1-based board that I designed myself, running the 202504-dev firmware on an NA Miata with a 4G63 trigger pattern. My question is: In Tuner Studio, why does the Advance Gauge (Spark Table 1) read 10 degrees higher than the value in the Spark Table? The same issue occurs when setting timing with Locked Timing—it always ends up 10 degrees higher than what the Spark Table shows. Is there an offset causing this, or is this expected behavior?

Regards,
AndyA

It's possibly something in your tune. Can you share it?

Thanks! You're probably right that my tune is off due to my bumbling around with it—assuming this isn't normal behaviour. I'll redo the tune from scratch and report back.

Ensure you load a base tune. Don't just key into TS.

Thanks, everyone! The problem was solved—it was due to the Flex Fuel being on.
