Maik Maier Posted April 11, 2015 Report Share Posted April 11, 2015 Hi,  I have a problem with my 2000 Mazda Miata and my Link G4 Xtreme. Right now I'm in the progess of setting up the ECU. But I have a major problem with the Trigger Signal. I'm using a 2000 1.8 BP Engine Block with a 2004 VVT Head. For best sensorical performance I use a 36-2 trigger wheel. I setted up the car with MultiTooth/Missing Trigger wheel 1. Using double wasted spark the engine fires up, as it should. But when setting up Trigger 2 and Sync the sensor Signal mess up showing RPM's up to 18.000 rpm while cranking. The is caused by a wrong Sync Mode. I used 'Cam Pulse 1x', but the VVT Miata head has a Trigger wheel with 1 tooth and 2 thooth 180° opposite. Is there a way to change the Sync mode? I really want to use direct spark and the VVT, so I need the right setting.Is there a way to realise it? I really don't want to use the genuine 4 tooth trigger wheel with the prepared setting. I attached the actual Trigger settings and the trigger signal the way the should be (see picture: Red: Cranksignal; Green: Cam/Sync-Signal; Blue: Igniter).Thanks in advance.Maik  Trigger Mode: MultiTooth / Missing Trigger Priority: Trig 1  Trigger 1 Type: Optical/Hall Trigger 1 Filtering: Level 2 Trigger 1 Pullup: On Trig 1 Edge: Rising Multi-Tooth Posn: Crank Thooth Count: 36 Missing Teeth: 2  Trigger 2 Type: Optical/Hall Trigger 2 Filtering: Level 2 Trigger 2 Pullup: On Trig 2 Edge: Rising Sync Mode: Cam Pulse 1x    Quote Link to comment Share on other sites More sharing options...
Simon Posted April 15, 2015 Report Share Posted April 15, 2015 Hi Maik  I think the easiest option is to go back to the stock crank sensor. The other way would be to add a single tooth cam trigger to the exhaust cam and use that for the RPM engine position combined with the crank trigger. You can then put the intake sensor signal into a Di and control the vvt then. Quote Link to comment Share on other sites More sharing options...
AN7 Posted August 4, 2021 Report Share Posted August 4, 2021 Sorry for Resurecting an old thread, As I have a miata with similar engine setup(1.8 vvt and sequential spark with cops) I was planning to go to 36-2 trigger wheel for better crank position resolution. So this is a no go without additional Triger? Quote Link to comment Share on other sites More sharing options...
dx4picco Posted August 4, 2021 Report Share Posted August 4, 2021 What ecu do you have? On older ecus you would not be able to run sequential without can trigger. But you would still be able to run wasted spark Quote Link to comment Share on other sites More sharing options...
AN7 Posted August 4, 2021 Report Share Posted August 4, 2021 G4 storm There is a cam trigger but its a weird one, i am already running sequential with the original trigger setup (4tooth crank wheel). Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 5, 2021 Report Share Posted August 5, 2021 Im 90% certain the toyota 2GR trigger mode will work with this 36-2 + 3tooth cam combo but I dont know if anyone has tried with a G4. I cant really test in house so it would be a "suck it and see" at your risk. AN7 1 Quote Link to comment Share on other sites More sharing options...
AN7 Posted August 5, 2021 Report Share Posted August 5, 2021 Hm, interesting. Do the new G4X ECUs support that out of the box? Quote Link to comment Share on other sites More sharing options...
