Changing to Crane Electronic Ignitition

I have a 1972 280se 108.067 4.5 Mercedes. I had a problem with the
Ignition COntrol Unit and placed a wire in the car's plugin recepticle
(to ICU) connecting 2 of the plugins tabs. Thus bypassing the ICU
completely. I have tried a new ICU and it didn't solve my problem. It
runs??
My question is, by installing a Crane Electronic Ignition, will this
eleviate the ICU problem and improve the car's performance?
Thank you for reading this inquiry.
