Nope MGP is all you will need, Assuming MAP and BAP are functioning correctly

It would use up the same amount of I/O as doing it internally. The ECU still has to have the 4 volt inputs and the 3 Aux channels in use for it to operate.

The catch with the ABS pick up is the frequency will be too high for the Di channels. You need much less teeth to keep the frequency below 500Hz at top speed. You can run a 5th speed input but its not needed as all functions will operate via the wheel speeds.

If you are measuring that voltage drop across the relay and using the same ground for each measurement then it is not ECU related. There is something up in that relay area.

Miss fire could be due to the crank polarity being incorrect. You need to swap the signal and ground at the sensor. Dwell will likely need to be lowered for the GTR coils. To arounds 2ms at 14V

Can you post your map, Make sure all motorsport features are off gear cut and launch in particular.

What is the terminal connection like on pin 5 of the relay if that was not making a good connection changing relay will have no effect as the issues is the actual terminal

Check the voltage across the ECCS relay it could be the relay

There is no trig 1 errors counting up during the log looks like a couple on start up but that is fine so I suspect the triggers are happy. What coils are you running as you have relatively high dwell numbers for a multi coil setup. Can you get a trigger scope capture at idle as well so we can check the sensor voltages and polarity.

MAP of 0 is 100% vacuum A typical idle MAP would be about 60 It will activate what any one condition is met. Using a virtual Aux is handy if you want a bunch of and conditions. The PC logging captures the data just prior to your logging request so that you can catch an event even if you didn't start with logging on.

Best to send an email to [email protected] and we can sort form there

Pull the start up steps to a smaller number ( on these a lower number will give a lower idle increase)

Most factory applications will have a suppressor on the power feed to the coils any factory one would be fine. (Its not really that critical) Oil pressure sensor should be fine assuming it is happy with a 12V feed. Regards Simon

Is it a stock tach? Was it originally driven from an ECU

Set the trigger 2 VVT to off (this is only used for fully variable cam control). Then use either cam level or cam x1, which ever gives you good stable RPM and not Trig 1 errors.

If you are getting trigger errors its not going to be fine. There will be some timing scatter happening. Both modes could be used but Level is the better option as it allows the engine to sync in half a cycle. Make sure your trig 1 edge is set to falling Trig 2 vvt should be off and the Aux should be Cam switched for the cam control (No VVT settings should be in use)

Nope you have to use drives 1-4.

You can wire to 12V or ground and then just configure the DI pullup to suit. Pullup will need to be on for a ground switch and off for a 12V input.

You should be following the power supply wiring information in the help file. There are a few variations depending on if you want to use ECU hold power or not. Head to the PC link help file then Wiring Information > Power and Ground Wiring > Power supplies

Can confirm it is a V44 based unit so no Knock control and no E throttle onboard.

Two sensors would be totally fine to that wire

From a Trigger side the ECU is seeing a sensible RPM and no trigger errors during crank. There are no ignition or fuel cuts active so from the ECU I would say it is trying to fire the engine up. Can you confirm if you have spark at the plugs, And there is fuel at the injectors / getting into the engine.

Yep that would be fine

Best way to fault find this would be to have a scope on the signal to see what is happening. You could also se the input on the ECU to a Frequency input and see if that gives an unstable frequency

You will have to fabricate something to suit. That pattern is not supported. I would look to removing that wheel and pressing on a 24 tooth wheel with a tooth removed.
