Simon Posted November 28, 2013 Report Share Posted November 28, 2013 There is a good chance you timing offset is out. With a distributor there are 4 offsets that will work each being 180deg apart from each other. You will need to check your timing on #1 cylinder and adjust the timing offset to suit.

bsh Posted November 29, 2013 Report Share Posted November 29, 2013 What kind of trigger pattern are you running in the dizzy? Are you running 2 trigger sensors? Remember if you are running 1 sensor, you must use a pattern with ie a missing tooth so the ecu knows where in the 720 egree cycle the engine are since you are running direct spark with 4 ign outputs. Are you running 2 triggers in dizzy, one of them are for sync. ie 4 teeth for trig1 and 1 tooth for trig 2. (like early Evo 1-3) Quote Link to comment Share on other sites More sharing options...

davidbek95 Posted November 30, 2013 Author Report Share Posted November 30, 2013 I have just gone through my wiring diagram for my triggers set up,this how it wired,A8,trigger1 is wired to cylinder pulse,A9 trigger2 is sync pulse, power,red/white is power supply,2 whites are sensor ground. regards david Quote Link to comment Share on other sites More sharing options...
bsh Posted November 30, 2013 Report Share Posted November 30, 2013 You must lock ignition and setup offset using a timing gun. Adjust offset till actual timing is the same as in software. If you dont know how to do this prosedure, see software for help. Help function in software is very, very good. How is trigger 2 setup? In runtime values(press R), triggers/limits do you see a steady 200 rpm while cranking and trig1 and trig2 signal "Yes"? Quote Link to comment Share on other sites More sharing options...

bsh Posted December 1, 2013 Report Share Posted December 1, 2013 email sent. I noticed after I sent the email, that I put abit low dwell in the 12-14V region. You can safely raise to about 4 ms. Quote Link to comment Share on other sites More sharing options...
