Anthony Parle Posted October 4, 2016 Report Share Posted October 4, 2016 Hi Guys, Link G4+ Thunder I want to run Bosch coils on plug and they require 73mA each to run them I will run 6 of. Is that with in the ability of the Link ECU to run them. Attached is the tech doc from Bosch in case I have read something incorrectly.

Scott Posted October 5, 2016 Report Share Posted October 5, 2016 Hi Tony,Each ignition output on the Link ECUs will put out pulses at ~ +5V and can provide up to 20 mA of current. I think this will work fine with the Bosch coils you are looking at as the say:Scott TTP 1 Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted October 19, 2016 Author Report Share Posted October 19, 2016 Hi Scott,I am getting old and I can't remember if I asked or ment to ask,When you have the ECU in test mode for spark at what rate does it fire the spark?

Scott Posted October 19, 2016 Report Share Posted October 19, 2016 Hi Tony, the Ignition Test function occurs at 10 Hz and the pulse is 5mS.Scott. Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted October 19, 2016 Author Report Share Posted October 19, 2016 Hi Scott,This might sound like a dumb suggestion but it maybe worth you guys letting the tuner adjust that number if they want.The reason would be that at that rate a 4 stroke engine is doing 1,200, if the tuner could adjust it he would be able to check if the spark is still good at higher rpm. If he suspect he has a problem with a coil it would be a method to check it. In my case I believe the plug coils I have are not making the grade but can't confirm that.

Scott Posted October 19, 2016 Report Share Posted October 19, 2016 Hi Tony,Having things more controllable by the user is a good suggestion, there could be a number of times having the ignition test customisable could be useful. I will ask the engineers to consider adding this to the wishlist.One difference that could have an effect between testing the ignition system at high frequency and actual running is the in cylinder pressure. Maybe some other tuners on the forum will add their thoughts on this.Scott. Quote Link to comment Share on other sites More sharing options...
Rossobianconero Posted October 26, 2016 Report Share Posted October 26, 2016 One difference that could have an effect between testing the ignition system at high frequency and actual running is the in cylinder pressure. Maybe some other tuners on the forum will add their thoughts on this.Scott.Scott is right about the effect of the cylinder pressure on the ignition system, you could be running 1 bar of boost without problems, and then turn the boost up and you start having misfire on the engine at the same RPM that you were fine before (but at less boost). So the cylinder pressure is a big factor in the ignition system. Quote Link to comment Share on other sites More sharing options...
