Fl. Their number is 888-593-2262. See if they can help you.

yeah let us know what they charging

And what is your car doing that you think the ECM is the problem?

It has an intermittent misfire. It runs great and then it loses a cylinder. I replaced the ignition module first and all injectors plugs and wires. Still did it, so I pulled the ECM and had it run in another ZR1 with no problems and it duplicated the misfire after about 10 mins of running. Sure hope this is the problem.

I had a very sililar problem some years ago. In my case it was caused by me back probing the injector pins at the ECM plug. Big no no.
