MBE 967 ecu

On the MBE967 ecu, pins 1 and 26 are listed as Fuel Trim and Ignition Trim.

I know these pins can used to allow the ecu to communicate with dataloggers/computers, but based on their pin names, is it possible to use them to remotely trim Fuel/Ignition during operation?

Those pins work with a dedicated "mapping" controller used when the engine is tuned on the dyno. I believe they are only active when the Easimap software is connected, and a map is open and enabled for live editing. They certainly wouldn't do anything without the computer attached, based on my experience with MBE software.

OK, thank you!
