Assuming you are on the base map and wiring is stock neither of those will be an issue when it comes to starting.
You will however have to change the trigger settings to suit the Kiggly 12 tooth crank trigger. The cam wheel for trig 2 will also need a tooth removed.
Trigger Mode will need to be changed to Multi tooth.
And settings for trig 1 set to the 12 tooth crank and trig 2 to CAM x1
-
To confirm if the issue is internal put a volt meter between an ECU ground pin and the 14V in back probing the header and check if meter matches ECU or not.
-
Keep it to under 500mA and you will be fine on the 5V out.
Yes the ground is common.

Trig 2 falling to rising is worth a shot. I suspect its not going to be better but it is something you can try easy

Looking at your trigger scope closer today I notice your trigger 2 signal is inverted compared to what the ecu is expecting. How sure are you that it is the LH Inlet cam sensor that is connected to trigger 2 pin? The reason I ask is from what I can tell, the LH exhaust signal is meant to be inverted like your trigger 2. So maybe the inlet/exhaust are wired to the wrong pins? Or maybe the exhaust/inlet sensors are fitted in the wrong holes? (I dont know if they are the same part number/interchangable?)
Im not sure if this is the problem or not yet but many VVT trigger modes use a "level" for sync rather than the edge so it may not be just as simple as changing the edge setting to rising.
@Simon, could you confirm with engineering if this scope would work correctly with the EZ36 triggermode - trigg 2 is inverted compared to the sim and Link documentation, seems to loose sync when the cam advances? I suspect this decoder may use a level sync or edge count that is failing due to the inverted signal. Will swapping trigger 2 edge setting work for this mode?
You could try changing the edge on trig 2 but that trigger scope looks almost spot on to what is expected. (EZ30 differs in polarity but falling edge is in same spot)
-
The EZ motor needs the 12V the EJ sensors shown above are different to your application.
You need 12V supply
-
One possibility is you are 360 out on the offset so you are firing on the exhaust stroke.
The other is the fuel needs adjusting to get it to fire.
-
Being plugin start with the V7-9 map as this will have the I/O configured correctly. Then change the triggers to suit the later motor.

Hi, what directory have you installed PCLink to?
When PC link was installed did you put it in the default locations?

Good work not an easy task adding a tooth.
-
It could well be hardware related. As the ECU temp rises it will expand and if there is a suspect joint its likely to cause issues.
There is no firmware control around temp on the Ignition switch input
-
There might be others that have this down.But I know on some of the earlier BMW applications the BMW mini can stream worked for a lot of the dash data. (e46)
-
Temp 1 and 2 have selectable pullups 3 and 4 don't. But if your temp is reading correct you are good to go
-
The Id is user defined. The stream layout can be found in the PC linkhelp file. There are a few different options.

Will be a slight increase in price. Trim correction is on the wishlist so not there currently but likely to happen.
-
Just need to have 5.6.7.3631firmware installed in the ECU. You can check current firmware but connecting to ECU and then going to the Help tab and then ECU info.

Aux 11, through to 16 are not connected to an external connector.

You will need a free temp or AN volt channel. On side of the sensor to sensor ground and the other to the input.
If using a AN volt you will also need an external pullup to 5V on the singnal
-
So do you have a serial link currently? (they are still available)
Not all G1 units were able to be PC tuned and it is dependent on the firmware. TO check this see if you can see a sticker on the main micro and put those details up and we can advise.
-
The Offset figure will depend on which cam tooth has been removed. But this can be found relatively quickly when doing the timing calibration.
Also note that you will need to change the wiring for the Tacho to a available Aux output on the ECU as in stock format it is driven from the crank signal on our plugin.
-
It comes down to the coil as to what the needed dwell is going to be. I would assume that table is for stock coils.
If the dwell is too short you loose spark energy. If it is too long you risk overheating the coils.
I would try increased dwell time and see if it improves. While keeping an eye on the coil temps.
-
Unfortunately there is nothing existing for that. The other Rover patterns are 3 teeth missing at uneven spacing.
Maybe adding a tooth back so it becomes 36-1?

Number of and type of I/O will be mostly unchanged. Most of the changes will be firmware based.

That one needs the CAM sync.
