hi i am just converting to fuel injection with a ms3 megasquirt but i cant find any info as to wether i need to fit separate ignition coil suppressors to the coil on plug coils in the instructions it said to fit one to a coil pack but nothing about cop,s any info would be gratefully received

I run Hayabusa COPs on my car running from an MS2 fitted with four spark outputs. I have a noise suppression cap and a ferrite on the common 12V supply but no other caps. Works fine.

I dont think they are needed for logic level coils on MS3.

Also, which manual are you using? Best off using the ones on http://www.msextra.com/ which also has a really good forum.

Hi Stuart I am using the efi extra wiring diagram

Not needed, I didn't use one when I used a ford coil pack with an MS2 using BIP373 high current driver.

Also not using one on Lexus 1UZ-FE ignitors

You'll be fine

Ok thanks will try without
