Edis 4 send short 25500 rpm peak signal to Ms.Whats wrong?

Post by Jonas N »

Hi

Have a Edis 4 and MS V2.2

And when connect power to the Edis module it send a short high rpm (25500 rpm) signal to Ms. For about one second.Then it dissaper for 2 seconds.And so on.

The injector runs at 170% and the pulse width is same as Cranking value. Somtimes littel higer.
Baecause the high rpm the injectors runs over ther limit.

If i wait to long this process destroy the sparkpluggs. If i start it up directly it dissapear and the enginge runs normal. And no more high rpm pulses.

I also Run the fuel pumps from MS control. Prime pulse higer then zero. Then the pumps should runs 3 second if things normal.

My fuel pump never stops. Ms Gets signals that the engine is running every two seconds they never shut down.

Tried have the VR sensor not connect to Edis module. No diffrent

Anyone have the same problem.

Dont want to change any more sparkpluggs :evil:
