i have opened up the suspect ecu. 700

well i had another used ecu put in last week and so far 100 miles with no problems.

so today i decided to open up the ecu and see if i could see a bad solder joint or something.

i immediately noticed upon getting it open that on the right side (plug facing forward) there is a 1" x 2" board that appears to be coated in silicon with these two raised pyramid things on it that have a black cross across the top of them. on one of them the surface is broken a bit and there appears to be a hole in it (the metal cross is exposed). could this be the cause of my ecu woes? i am guess it should not be like this.

if i can find my torx bits i will remove the board to look for cracked solder joints on the other side.

i will try to take a picture later tonight.
