Rossogy Posted May 2, 2022 Report Share Posted May 2, 2022 Hi guys, Just off the dyno with a mates car and we are having bad trigger issues so im looking for advice. We have changes both crank & cam wires to shielded wires & checked all earth points. this all made it alot better but there is still something holding us back from reaching our rpm limiter. i will attach my tune & Log for advice. you will see the weird spike in rpm reaching 11-12000 rpm. Any advice on where to go from here would be appreciated. We have ordered a new crank trigger wheel which is our next port of call. Thanks guys. 1.5JZ trigger issue.pclr callum trigger issue 6600.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 2, 2022 Report Share Posted May 2, 2022 Will need some triggerscopes doing at high RPM. I would drop trigger 1 filtering down to level 1, level 3 is possibly too high for a high tooth count wheel. Quote Link to comment Share on other sites More sharing options...
Rossogy Posted May 3, 2022 Author Report Share Posted May 3, 2022 Hi Adam, attached logs with filter level 3 & then filter level 1. Let me know what you think. Cheers 5000rpm.llg 6000rpm.llg 5000rpm filter 1.llg 6000rmp filter 1.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 3, 2022 Report Share Posted May 3, 2022 Definately the voltage improves a lot with the filter reduced so that could potentially be the cause of the problem. So leave the filter on level one and drop the arming threshold at 7000 back to 3V. Let us know if that helps. Quote Link to comment Share on other sites More sharing options...
