I've had my MegaJolt installed on my air cooled VW motor for a little more than a year. I have NEVER gotten all the bugs worked out.... Now I have more issues.
The software suddenly stops "talking" to the MegaJolt. I can start the motor and the software will display the RPM etc for about 10-15 secs and then it says it cannot find the port.
I have tried uninstalling and reinstalling the software and I do not see any improvement.
This is after pulling my hair out over a continuous misfire that I can't explain or eliminate...
I'm real close to going back to a distributor.....
Any suggestions?

Sorry you're experiencing problems.
So we have seen cases where USB to Serial adapters get interference from the ignition system of the vehicle, causing them to 'lock up' and lose signal as you've described.
People have solved this by switching to a different brand USB to Serial adapter (typically a higher quality one), or; physically extending the computer *away* from the engine by using a serial extension cable.
Also, if you have access to a laptop with a real built in serial port where you don't need a USB-Serial adapter that seems to solve these types of problems as well.
