Frallam Posted September 10, 2017 Report Share Posted September 10, 2017 Hi!I have a problem with my car, a nissan 200sx s13 with a ca18det running a Link g4+ storm blue. It cuts the ignition(i think) when it reaches a certain rpm. First with the stock Cas (360 degrees) it would cut @ 4000rpm when in gear and around 5000rpm when in neutral standing still, i had a local tuner look at it and they said it was missing the trigger and suggested i change to a 24-1 dirc inside the cas instead, said and done. I change the trigger to multi tooth and calibrate the ignition timing with a light and it works fine. starts right up and runs good, i let it get warm and then i try and rev it, 6000rpm standing still, no problem so i decide to take it for a spin and it revs to 4500rpm and then it cuts and wont rev higher. (if your need more info about the car/engine just ask) i'll attach the MAP and the LOGs of the 2 testruns i did. . Any ideas?

Adamw Posted September 11, 2017 Report Share Posted September 11, 2017 I dont see too much signs of trigger error in either log. In "test 1" the dwell is a bit wobbly in a couple of areas which could indicate the trigger is not perfect but that effect is only very intermittent and I dont see it get worse with RPM etc. There are no limiters or "cuts" being activated at all. However, to be thorough, it would be worth doing a trigger scope at idle so we can check the edges look ok?I suspect the problem is external - Maybe ignition system?

Frallam Posted September 11, 2017 Author Report Share Posted September 11, 2017 How do i do a trigger scope? i might be blind but i cant find the option.I'm using ngk bcpr7es plugs and the "yellow jacket coil packs" controlled directly by the ecu, maybe thats the problem? Maybe i should rebuild it with VAG coils instead? Quote Link to comment Share on other sites More sharing options...
Frallam Posted September 11, 2017 Author Report Share Posted September 11, 2017 (edited) Here is the trigger scope logTrigger Scope Log 2017-09-11 10;35;24 pm.llg I dont se any trigger errors at all anymore, i can rev to 6500+ standing still but it still cuts at around 4500 when driving Edited September 11, 2017 by Frallam Quote Link to comment Share on other sites More sharing options...
Simon Posted September 12, 2017 Report Share Posted September 12, 2017 (edited) The trigger 1 signal is not pulling to ground fully I would check the ground to the CAS is 100% and maybe try another CASBut I more lean towards it being something else outside of the ECU as in the first logs there is no sign of a trigger issue or any limit / cut being applied by the ECU Edited September 13, 2017 by Simon typo Quote Link to comment Share on other sites More sharing options...
Frallam Posted September 13, 2017 Author Report Share Posted September 13, 2017 Yeah, reseted the ecu, updated the firmware and loaded the map again, still same issue. So now i have ordered VAG coils and i hope that will fix my problem Quote Link to comment Share on other sites More sharing options...
