LLM for ARL: Key Differences Explained

Hello everyone,
I wanted to get a new mass airflow sensor (MAF) for my 'friend.' However, there are two different versions, one with an 'A' and one with a 'B' after the part number. The one with the 'B' has a different grid pattern (a smaller grid within a larger one). The 'A' version is the same as the original one that came with my ARL engine (manufactured in 4/2001).

Is the B variant an improved version? Has anyone logged any data or gained any experience with it?

'How does it work with your ARL engines? In mine, the fuel injection amount is limited by the rev limiter up to 1700 RPM. However, I've seen diagrams online where the torque limiter seems to be the limiting factor.'

Best regards,
