I have attached a link of this information for your review.

Bullfrog: Nice engine pic! I understood what you meant but I found the noise in the fan for cooling the ECU. It is at the front of the ECU black box and when it is making the noise I can actually grab the active fan and the noise changes, so it is just the fan itself. Thanks for the input. I'll let you know for sure when DC does the job.
