Ok,I have been reading about inconsistent performance from the DIS module related to heat. I had a problem with the tach quiting after a few miles of driving. One of the guys on the board came up with the great idea of putting fresh heat transfer compound on the mounting surface and re-snugging it down. I did that, and it worked for a few days, and started doing the same thing again. I came up with the idea of building a heat sink under it, and useing longer bolts to mount it. This worked well until I let it get up to around 210 deg. and it quit again. I was just hanging out under the hood trying to figure out what went wrong when I noticed the the module itself was slightly bowed up in the middle. This would cause the contact between the heat sink and module to break leaving nowhere for the heat to go. I fabricated a small brace that goes across the module so that when the bolts are tightened the bow is pressed back to original. It is my guess that this is what is happening to alot of SC owners out there. I will take some pics of my heat sink and brace system tomorrow, and post it up. Oh yea, and my SC hasn't missed a beat since. Later
