Cartech FMU

Theres an adjustment bolt (hex) on top of a Cartech FMU I just got... Is letting the bolt out or tightening it up for enrichment?

Re:Cartech FMU

I would say tighten it in to make it richer. That will raise the fuel pressure to the injectors. But I'm not familiar with FMU's so maybe someone else will answer too.

Re:Cartech FMU

So threading/tightening the bolt into the FMU is rich. And letting the bolt out, is lean?
