i was thinking if i wrote a zero to the fuel trims memory address using DMA. would that reset them. i ask this as i understand some mut addresses are actual memory addresses of the thing while others are calcualted. so if it the mut memory address for the trims was calculated then even if i overwrote it, it would reset back to what it was.

basically tuning injectors and pulling the ecu plug can be a pain.

 

so no one knows if the ram addresses in mut table are the actual addresses for fuel trims or derived ones?
