I don't have direct control over the ignition right now, apart from resetting the ECU so that the max advance 'targets' are re-established.

It is interesting that a 0.4mm is more effective.
I've got the 0.5mm now, datalogged some runs on the accelerometer.
More boost too, 18-19psi
Haven't transfered the results yet.

I am sure the vacuum will make it flow more.

I wonder if we can use the pressure formula we use for fuel injectors:

If the ERL pump operates at 10bar normally, we could say that at 1 bar the pressure across the nozzle is 9 bar.
Precompressor, the equivalent pressure would be 10.5bar perhaps.

Any ideas why the above thinking might be wrong?
