I was curious, I took my DIS Module off a while back and noticed it had some sort of white greasy compound on the back of it and I was wondering if any of you know what it is? Im putting a new DIS on my car real soon so I need to know what to put on the back, is it some sort of thermal compound like you'd use on a computer processor between the processor and the fan/heatsink or is it just some like white lithium grease?
