scott87star Posted August 28, 2014 Report Share Posted August 28, 2014 You have two logic level spark signals out from your controller on the square weatherpak connector (four position). Looking AT the male connector with the lock tab up the upper left is spark A and the lower right spark B. You can just split each to the trigger input for two coils, spark A for 1&4, spark B for 2&3. Are they the coils with the heat sink built in? Those have severe dwell sensitivity. Link to comment Share on other sites More sharing options...

scott87star Posted August 28, 2014 Report Share Posted August 28, 2014 Most of the tuners I've spoken with won't touch those, anything over 3 mS and they randomly fire. Link to comment Share on other sites More sharing options...
stariondreams Posted August 30, 2014 Author Report Share Posted August 30, 2014 Wow sad to hear that I came across 2 sets a few yrs ago and people then were loving them because they are easy to install so what would you suggest? VW's please note I work at Lexus as a tech maybe any of the Toyota's or Lexus i have a ton of those laying around Link to comment Share on other sites More sharing options...
scott87star Posted August 30, 2014 Report Share Posted August 30, 2014 Any of the smart (4 wire) coils would be fine. Link to comment Share on other sites More sharing options...
