arttunedph Posted August 22, 2021 Report Share Posted August 22, 2021 (edited) 2JZ VVTI Hello! Anybody here having issues with unstable triggers for 2JZ VVTI on a G4X ? No start, trigger 1 does not remain a steady green and rpm fluctuates. Prior to installing the 2JZ VVTI was using a 2JZ Non VVTI on the same harness and ECU, no problems at all. Also inspected the trigger wheel 36-2 and tried different sensors still the same problem. checked CAM for trigger 2 all good, tried different cam sensors still the same problem. inverted possitive and negative wires for tirggers, ran new wires and sockets for cam and crank outside the vehicle still same problem. Adjusted the filters and voltage references still the same. finally replaced the storm with a different one and still the same.

Adamw Posted August 22, 2021 Report Share Posted August 22, 2021 Please do a trigger scope while cranking and attach that and a copy of your tune. Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 22, 2021 Report Share Posted August 22, 2021 Your trigger voltages are below your arming threshold. Try 0.2V in the first cell in both trig 1 & 2 arming threshold tables. Trig 2 threshold table needs fixing at 4000RPM and above too. Adjust all orange cells to look like mine below. Quote Link to comment Share on other sites More sharing options...
