Anyone that is running the zex 75 shot on thier 2.2, what did you do about your timing. The reason im asking is that i've heard that our timing is electronically controlled, is this true?...If so, what can be done? May be buy adjustable cam gears?

 

it is ignition timing that needs to be retarded not cam timing

it can be done by an MSD DIS 2 but other than that it can't really be changed

 

Thats right. Thanks for catching that. Do you the DIS installed?

 

no, I don't know anyone with an Ion or Cobalt 2.2 who is actually running it.

I'm sure it might be beneficial but you don't necessarily "need" it

 

I am running a 75 shot on my 2.2 and did not change a thing, but the plugs.
