That lambda table has a LOT of resolution.. the lambda table in my Ecumaster BLACK is maybe one quarter the size...

From what I’ve learned about ITBs, resolution in the low throttle range is critical—small changes in throttle position can have a big impact on airflow and drivability.

Is that why I bought the Haltech R3? Honestly, no—I bought it because it was on sale. But I’m glad I did. I really like having all the power and I/O wiring integrated into the unit. It makes for a clean install and simplifies a lot of the setup.

So far, so good. The ECU has what feels like a million settings you can tweak. I’ll admit, it was a bit overwhelming at first. When I couldn’t find answers here, I leaned on AI to help me sort through some of it. Still, I’d like to get it to a professional tuner like Rivet at some point to really dial it in.
