Is ECU wiring loom lenght important?
Posted: Tue Dec 26, 2017 6:04 am
Hi All,
I have a project where I am fitting a Mercedes M120 V12 out of '93 600SL into a '62 W111 Coupe. I would like to keep the original engine management system for now (2 ECUs - one per cylinder bank - and one ECU for electronic throttle actuation) and look into Megasquirt later, when I have worked out a new intake system and camshafts. I would like however to fit the ECUs in the trunk, together with the battery. That would mean lenghtening the original wiring loom. Will the lenght of the loom affect the nature or quality of the signals from the sensors? I guess Megasquirt versatility can compensate for this, but how will a stock system react to an additional 6 feet of wiring?
Thanks for the help, and Merry Christmas!
