The DMS4 EZI is one chip to stay clear of. Not because its a poor chip.... but the clip kits design is less then desirable. The EZI line of chips will eat your console for lunch. The solderless clips will bend and break the chip legs rendering your console useless.
I have had a few people now send me there EZI install in an attempt to save it after the damage the EZI has done to there console.
Here is a DMS4 EZI converted to a proper solder install. I was also able to save this console from the grave after the initial install.
Swap discs do suck and I would recommend being patent and doing it correctly.
