Not sure. I got the slim DDM kit for around 35 bucks direct from them and I am also using their error eliminator canbus harness on my car. They work perfect when its full ddm tuning stuff with my morimotor bulbs. No errors or any flickering.

The problem I am having is that i'm using the ddm canbus error eliminator harness with the 55watt morimotor kit. Supposidly the 55watt kit isn't getting enough power during warm up which is causing the light to flicker. I ordered the morimoto canbus harness now and waiting to try that. Basically i'll have one set of full ddm and one set of morimotor after this.

I'm skeptical about using the 55watt kit now because they are so damn bright. If the 3000k yellow bulbs are still too bright i may end up adding a light smoke tint over my fogs so it protects the lens from rocks and also tones down how crazy bright they are.
