  1. I get 0.4 ohms Thanks for your help, I will fit a set of coils with built in ignitors.
  2. Do you have any information on the wiring of this Bosch coil?
  3. That is what this car is doing, it runs but very badly.
  4. So it's actually possible to get a spark out of the coil even though it doesn't have a built in ignitor? I'm not 100% sure, I didn't build or wire this one, it just came in for tuning. I hate it when they arrive on a tow truck! Just wired in a R8 coil I had laying about for testing and the spark is very strong.
  5. Hi I have a car in for tuning that runs very badly, at first I thought it was a trigger issue due to the cam and crank signals being at the same time. While swapping trigger edge for the cam I noticed the spark is so weak that I cannot get my timing light to trigger. Coils are BOSCH 0221504006. Testing the coil outputs in the software I have sparks that will barely jump a 2/3mm gap, Is this normal for the test mode or should I see full power?
