It's working now, as long as I bypass the wiring from the vehicle and use test leads. So something is now up with the wiring. What does the switch condition set at 0.24 change if the value is changed?

I have it switching correctly now but it's still not activating the solenoid. Resistance when set at 2k on a multimeter is showing .040

It doesn't need to have a switch positive but it does need an earth. It has two wires, when wired up as you suggested in the above diagram nothing happens. Whereas if I give it either a permanent earth and switched live or permanent live and switched earth it operates. I hope that makes sense. I am running a g4+ storm.

I've bench tested one solenoid I have which does work like this but this just keeps the Vic's on. Whereas the other solenoid I have requires an earth and then a live feed to active and does what is required. Is there a way to get this one to work at a set rpm?

Sorry to bring this topic back up again as the process seems very simple, however on my G4+. I can't seem to get it to work. If I use a power probe with the car running I can get the solenoid and vac elements to work correctly however, if I wire this up to Aux 3 or Aux 5. The live wire earth's out until I disconnect the earth wire off the solenoid where the feed from the aux wire goes back to live. Either way nothing happens. Any ideas?

Probably something really simple but I am getting digital input 1 showing as active but off. However the input is not actually wired to anything. It has no affect on anything. More curious as to why it might be showing the above.

Thinking about this further, If I returned the crank wheel from 36-2 to the stock wheel, I could run a stock MX5 basemap which would be simpler? We replaced the stock though as whilst we were getting a good scope pattern we were not getting fuel or spark but when requested to fire as a test both would work. I am guessing this could be down to the fact that prior to going COP, the MX5 ran a wasted spark system. I know/think that elimination of the cam sensor would mean having to change the injection mode away from sequential to multipoint group (I think that would be the appropriate setting) but by grinding the two teeth of the cam wheel will this have any effect or can I still run the injection mode as sequential?

Brilliant, I kept it as MX5 due to being previously told to leave it, but will change. As I am running coil on plug due to limited space, I think I will need to grind the cam down to one tooth but will look at running it with a wasted spark system. I will have a play and see what works best, out of the options given.

A bit of a delay but some progress has been made: 1) Spark is present 2) Fuel is present 3) Crank Sensor is getting readings 4) Wiring replaced including plug for cam sensor 5) Cam sensor is new However, It its trying to start but doesn't, just checking to see if something is still amiss with sensors or settings within the ecu. I have attached a log. Chris Trigger Scope Log 2021-05-7 5;46;14 pm.llg

I have checked the settings and ran some trigger scopes. I managed to get spark on the last two but the timing isn't right as after the engine was not cranked, spark continued for a second or two at most Attached are todays scopes with the settings given above.

I have got the scope to read signals now and have attached a few samples for you. I changed the trigger and if the sensor was a optical/hall each time for the crank but not the cam. I am still not getting any spark or injectors working on cranking. Also, for some reason Digital input 1 is showing as off but active, however it appears that this is not connected to anything when I locate the pin on the ecu. Not sure what is going on here. I spoke to my friend who did the majority of the wiring and he was informed to swap the polarity of the crank sensor by someone at Link incase this gives any strange scope readings (however I am not sure why he was told to do this) Trigger Scope Log 2021-04-5 1;14;03 pm mazda MX5 - Reluctor.llg Trigger Scope Log 2021-04-5 1;15;29 pm mazda MX5 optical-hall.llg Trigger Scope Log 2021-04-5 1;16;58 pm 36-2 optical-hall.llg Trigger Scope Log 2021-04-5 1;17;58 pm UZFE VVTi optical-hall.llg Trigger Scope Log 2021-04-5 1;57;35 pm 1JZ VVTi - reluctor.llg Trigger Scope Log 2021-04-5 2;00;00 pm 1JZ optical-hall - rising edge.llg Trigger Scope Log 2021-04-5 2;00;00 pm 1JZ VVTi optical-hall - falling edge.llg Trigger Scope Log 2021-04-5 12;44;45 pm - 36-2 trigger - Reluctor.llg Trigger Scope Log 2021-04-5 12;47;57 pm -UZFE vvti Reluctor.llg Trigger Scope Log 2021-04-5 12;56;47 pm UZFE.llg

Hello, This has probably been done to death but I can't quite find the right answer. I have a 1.8 MX5 engine in a Vauxhall Firenza. I can get the coil packs (as it's converted to coil on plug) to fire on demand and the injectors to fire on demand but not when cranking the engine. The original pickup is now replaced with a 32-2 trigger wheel but nothing registers on the scope. I've set up the trigger to reflect this but nothing seems to work. Have I overlooked a setting somewhere? I get the feeling it's probably some very simple but not sure what. Any advice would be helpful.
