I got the same thing, I have gone as far as twisting the wires togather and still no signal. when i was first looking at buying it i remember someone else having the same problem but, now I cant find the thread:bang::bang:
Thunder Heart is saying to go into the module and change the tach calibration. Having alot of trouble with this module. Any other adjustable ignitions out there any one can recommend?
How did you get your computer to connect.
I have tried two different brands of USB to RS-232 and I still cannot get the software to link to the module.
