Likely to be a relay under there as the ecu has no moving parts unless you’re hearing electrical popping in which case you’d want to figure that out really quick I think?

Hi!

I've been trying to find out a lousy chattering noise from under the bench seat for a while now, and think I may have found it.

I have a 1990 Westy with an EJ22 conversion. On cold start, there's no noise from the back, but after the engine, then I start hearing a chattering noise. Thi happens at idle and low acceleration from idle. It sounds like it may be coming from the ECU. Has anybody else had this problem? Is this a way for the ECU to tell me it's about to fail?
?
Thanks!
