You say it doesn't do it with the blue box off? Maybe its possible the BlueBox and the EZ are confusing each other? Does the BlueBox have a built in Boost module? I know the EZ does so maybe they are both trying to talk to the ECM at the same time? Just ideas... ... . As long as your connection is tight it should be fine. Does it only do it with the EZ and BB both connected and on???

Need to isolate which box is causing it and then go from there.

As far as I know you need both boxes connected to the map sensor in someway for both of them to work properly. I do not have any personal experience with the BlueBox which is why I asked if it had a boost module in it.

I am betting thats where your trouble is. Need to "rethink" or rework how you are attaching to the MAP sensor. Might call Brett at Edge and ask him the bestway to piggyback the MAP sensor with another box.

Thats my suggestion.

Mass,

Unhook the ez and try it again. If you still have a miss it is the conection to the injection pump. Use a scoth lock with alittle silicon. You wont have any more problems. The green wire lets the box know how much boost you are making. If you leave it unhooked the box wont wait to see boost before it starts adding fuel. With a ez i would leave it hooked up. Keep you from over fueling the engine.

I second the idea of a call to Brett. We have a NW BOMBer here that is on his second EZ box... a stumble! He called Brett and I believe, is now returning for a refund.

I have never run anything but my BB. The addition of the EZ counts me out for advice.
