Hello Have RPM Limit reached warning coming up in my vipec plugin, this happens when the engine has 5500rpm? Sombody had the same problem? Frode

Engine is running.

Checked the voltage thats goes in to the ecu when crancking today, its not under 11volts"., the powersuply is ok i think.

i used the xp proffesional on the first pc and now i installed the software on a com with vista home premium.

i installed the vipec software on another computer, im getting this warning that the usb drivers may not work properly, and ask me if i want to install anyway., when i click yes i get the message it was installed sucsessfully?

I just tried to crank the engine again, now with a strong optima batt. The com goes offline just when i start cranking, butt comes online again after 2 sekunds during cranking,,the sparkplugs is also firing the 2 sekunds its goes offline. Frode

hello, thanks for answers. it is R sparkplugs, and i use the original harness since it is a plugin., does the harness cut power to the original ECU? will check if the spark plugs is still firing if it goes offline now. Frode

thanks, the engine is not running, its backfires when i try starting it.. not possible to check the ignition when its go offline. ill try a new battery and install the software on another computer.

Vipec goes offline when cranking the engine?
