Well they swapped Ian's and I'm sending mine in to be swapped. I don't know of any other D owners with the 3.57 box.

There guess it has to do with spark just makes me think the coil driver should not have shared the unit ground and should use a return (ground) connection external to the unit. I made this suggestion back when I first looked over the schematics. I would be willing to modify a unit with that change if you would like. Just to see if it would fix the problem.

I received my 3.57 box back today from DIY. They created a "solderless mod kit to change input inpedance" to match the 3.0 version. I put the box in the car and took it for a short drive. I can't get up to high speeds in my neighborhood but the car seemed to run well, except for a non-Megasquirt issue. When I got back home I put the car in park and revved the engine to close to redline with no sync loss. It appears that the problem has been fixed. I plan to spend more time on the car Saturday. Now for the fine tuning.

I've driven the car several times since I got the 3.57 box back with the change inside. I took the car out this evening and got up to 75 mph with no sync loss. I consider the problem fixed. I was having an issue with a sudden RPM drop while at a stop sign but that seems to have disappeared.
