I wanted to use the USB/Serial converter as I have more confidence in my new computer. I wondered what would happen if I connected the USB to Serial Converter to the serial cable and then connected the serial cable to the MJLJ. Doing this allowed me to move the USB serial converter away from the MJL...

I had my race car (1969 BMW 2002) at the track this weekend for the first time with the Megajolt setup. It ran great. The engine pulled happily to 8000 RPM which it would not do with the MSD system. The car ran very well and went faster than it ever has. However, I was exiting onto the front straigh...

I will be in Spokane next week to do a track day and hopefully get the car on a dyno.

Any thoughts on where I might find one of the USB adaptors that is known to work??

Thanks

I am trying to understand why ignition advance values typically stop increasing at somewhere between 3,000 and 4,000 RPM. If the timing is correct at say 38 degrees advance at 4,000 how can that still be the correct advance at 8,000 RPM? The time it takes the piston to travel from BDC to TDC at 8000...

I did not get to work on the car any more yesterday due to family committments. Today will be the same. I have to get a serial cable from somewhere before I can try the other cpu. I was wondering if there is some way to shield the USB cable. I expect the chip etc is in the serial connector itself. I...

There are VCP drivers that offer Virtual Control of the serial port and

D2XX drivers that allow dll's to directly control the USB.

Which should I be using?

Thanks

The Driver is v.2.0.0 5/19/2006

Is this the FTDI that is supposed to work?

THanks

Yes I have flashed the new version. Worked perfectly. The only difference is that before the screen would freeze immediately when the engine started. Now I get 20 to 30 seconds before it freezes.

The USB to Serial is a generic made in China one from the local Circuit City/Radio Shack store. It is all I can buy locally. THe other computer runs Win 98 and I don't have a serial cable so I have to go buy one at the same store. Should I be looking for a better USB to Serial cable? Any ideas? Jeff

Hi I have just installed an MLJ on my BMW 2002 racing car. The car starts and runs so the install appears functional. The problem is with the PC Connection. I can connect to the MLJ and read and write data to it. It communicates fine when the engine is not running. When I start the engine the run-ti...
