Megajolt loosing spark!

[starmag]

I have an A series turbo mini using the last megajolt before the V4 using all the needed ford parts. I have just put my engine back together and had it driving fine last week. It was running rich but i seem to have sorted this by redoing my choke seals and resetting the fuel pressure.


The problem i have now is that i seem to be loosing my spark just as i come onto boost. The car revs ok when no boost is created.

I have checked to make sure i have power to the megajolt unit, edis and coil pack when it misfires which it has. I can see this as the timing light stops working. I have removed my Vr sensor and cleaned the plug out as well as checking the gap to the trigger wheel.

Ive cleaned and gapped all the plugs.

When the misfire occurs the megajolt software goes to 0 and the rev counter drops to zero. The car starts to run when the revs drop back down and will misfire again just as it comes back upto boost.

Does anybody have any ideas as im abit lost? Also is there any way of checking the coil pack, edis and Vr sensor with a multimeter?

I have removed my hardcut unit and set the rev limit to 10000rpm
