Steve Posted November 18, 2016 Report Share Posted November 18, 2016 The best and only way I personaly recoment to fix this is with a crankfitted triggerwheel.However time is of the essense in your case.You should install that AEM disk in the cas and you will be good. You will still have timingscatter in real life but your ecu will not notice it so much causing it to hit the RPM limiter (your limiter is set to 9000 and the rpm spikes goes higher that that) and also will likely fix the trigger errors you get at that area. This will be your quick fix. You set it up as multi thooth in the trigger 1 settings and camx1 in the trigger 2 settings.You could also, just to try it out, set the low res mode to on in your triggersettings.But again. Real cranktrigger is your only real solution. This also applies to the Haltech... milton r33 1 Quote Link to comment Share on other sites More sharing options...

Top Tune NZ Posted November 18, 2016 Report Share Posted November 18, 2016 (edited) Hi milton it is a cas problem you are seeing have had it happen many many times the some times it is caused by timing belt whip and may not be directly a cas fault the link is sensitive to trigger isues at times on rb engines also make sure you have 12volt going to the cas at least, we have in the past i have fitted a triggger kit from nzwiring on my customers cars with great success also have you tuned the ignition map as retarded timin under boost can also cause the top end rpm to unstable 25 years of tuning rb engines trust me Edited November 18, 2016 by dobsondynotune Quote Link to comment Share on other sites More sharing options...

The stock cas got 360 small slots and 6 bigger ones?Not entierly sure i get your question...D could you check the log file and let me know ?i dont think this tuner is very cluey with the link set up ?i will check for 12v at the cas good point ..no the timing is set to 10% no timing yet. but i will mention it.. timing belt is tight but will check ..its a new engine so all parts a new..

Steve Posted November 18, 2016 Report Share Posted November 18, 2016 Ah. you just changed from the Nissan 360 opto trigger that was in your file to multithooth.You just change that number to whatever thoothcount you have. Just need to set the settings to whats right for your application. Quote Link to comment Share on other sites More sharing options...
