No, you either have a VB921 internal or 4G63 external ignitor (if you're running spark control with a megasquirt).

well i made a post on msextra.com because my idle has a good a/f and then it progressivly gets leaner. someone said that he had that problem and it was his hei module. do you think my vb921 went bad?

IAT heatsoak? Post a datalog and your MSQ. Usually you can find the problem by looking at the sensor data.
