3 Ohm Primaries and 4.5 Ohm secondaries, LINK have already calculated and supplied me 4.7 Ohm 25 watt resistors (they are anodized gold alloy mini heat sink type). On the further trace's ......When I rev'd the car and also when the car near stalled and the pulse width went well past 2m/s (closer to 3m/s range the patterns did not change from what I pictured) .

Wish me luck tomorrow, my patience is running out after doing such a marathon job building this car :sad: On a positive note the WI is working well and I have used about 2 liters so far and by accident ran 20 psi boost ops: due to a wrong setting on the boost controller :roll: but the 10.4:1 AFR and WI means she took it in her stride. I guess I should be thankful that my ECU drivers still work and my engine is in one piece since it looks like the FJO is faulty, will know if the problems magically disappear.when I test I take the injector plug off and use a pico 2pin bosch plug female/male and do the current clamp to it and voltage supply to the other, so its what is coming from the FJO output
