Alrighty then. I have all the bits off the Sierra that I need to convert my Esccos to big turbo. My question is, is there a way to keep my distr. less system or will I deff. need to put in the distributer and plug wires? Thanks for any help.

 

USE the new SECS S8 ECU! Then you can keep the current phase sensor + coil pack arrangement.

Speak to Simon at SECS (may be best to PM him).

 

Thanks. I went to the site and it seems to be different than before (not as much info and pics) I'll try to get a hold of him.
