So since im not running a IAC valve I need to try to have as stable as a idle I can. Before the external regulator, Megasquirt was seeing 13v-13.6. So, I installed my regulator sanded paint down and grounded it on my firewall. I started the car and megasquirt displayed 14.2v-14.6v, I was ecstatic but then maybe a hour after of messing with my idle/tunning. I relized my voltage slowly started declining back to what it was. Anyone have a similar experience or know my problem?
