  1. Hi there Todd, I'm not sure i understood this correctly, but you are saying that you have been using an aftermarket controller in order to control the variocam lift solenoid... I have done the same, and would really like to know what made you give up on it and preffer to go through this solution. What is it that you observed with the aftermarket controller? (poor idling, delayed return in low valve lift when rpms drop etc). If those were your symptoms do you think it was due to that controller's quality or what? i'm asking 'cause i'm looking for a better quality controller myself, one that has a quicker response in activating and especially deactivating the solenoids. I believe the whole problem is caused by the lack of throttle pedal position input signal to this controller. By the way, did you used to get the engine speed signal from the cluster, or from another source? Please suggest a specific brand of controller if you have something in mind. One last question: do you believe that the returnless fuel system is actually mandatory as Loren suggested earlier in the beginning of this forum? Happy holidays by the way, to you and everyone in the forum! (this would also include a wish for no more problematic conversions lol)
  2. Hi there! was curious to know what happened with your upgrade... Since you haven't replied yet, this is worrying! Please give us some feedback on your results when you can. Thanks
  3. Hallo Todd Is it possible to tell me what moifications you made in order to run your boxter with the 7.8 DME.I remind you that I put an 3.6 engine to a Carrera 4 3.4.I am still have problems with the Vario cams.I control the valve lifts with an external circuit but I cannot correctly control the cam timing.With the solenoids of variable timing connected, the car has a constand fluctuation on the RPM's.When I dicconnect them it is kind of slow at low RPM's but it's ok at high RPM's.So now I am thinking of replace the 7.2 DME to a 7.8 in order to have the correct solenoid controls.The only difficulty is that I have to have the engine head dismount in order to change again the ignition cam disk to an 3.6 original one because the one that I use now its converted(cutted) like the 3.4 engine. So Todd what would you do in my case?If you have any idea how I may do this engine to work correctly I would appreciate it and of course if you are able to sell me any documantation of the convertion it would be fine.Thank you
