I bought an M & W Pro 12 CDi Ignition for my EVO 9. Does any person know how to switch the power output of the said Pro 12 ignition module from 115 mj to 150mj high output mode ? Much appreciate and thanks !

 

Have you looked the installation pdf that is on the M&W webpage?

 

yes, I have. My friend. But I do not undertand what they mean. It read rather awkward and take thing for granted that you ought to know what is happening. M & W is not willing to explain the instruction any further and the supplier Spark Tech would never reply your request. Disappointing. Can you explain to me how to do so ?

 

I noticed that the new manual isn't the same that I have, but the old manual states that:

 

The instruction from M & W is different from yours. (a) Power Level Switch : It said "ground the input through either a "Hobbs" style pressure switch or mapped ECU output when elevated energy levels are required.
Or (b) Two Spark Switch : "ground the input manually or through a mapped ECU output."

What do you thing ?

 

Do you actually need the high output mode? If so, I would do what M&W suggests. Like I said, the old model CDI's didn't have that kind of instructions so maybe they have changed the CDI module or maybe there have been some problems running the high mode on all the time.

 

I do, in my case. Due to its short duration at low rpm and its power ouput is shared by two coils with wasted spark system, and it is not multi-spark set up, the W & M does not burn the lean fuel misture in full. Its drivability is not up to usual standard. It occasionally has flat spot and hesitate then even stall before the red light. Overall, it cannot handle the extremely high output turbo engine in loe output mode. Now I has fitted the MSD DIS 2 HO wasted spark system and the result is excellent. Any comment to my job done ? Lastly, I would tell you that I waste a lot of money on the M & W and preparing to sell it out. Somebody who know it well definitely would want it.
