Couldn't find anybody locally that had a new distributor cap in stock on Saturday morning, so I decided to pull my plans forward and fit a wasted spark ignition system using a six pack coil. Originally I was going to do this after the 10CR but I got carried away.
Managed to pick up a couple of second hand coil packs and leads on eBay, I used a Mondeo V6 coil and cut the leads to suit.
Dead easy to wire in and set up, just a couple of extra wires to the ECU and then reconfigure the software to run a wasted spark system.
The most time consuming part was making a new bracket for the coil and blanking off the distributor hole.
I basically hacksawed my old distributor mounting casting, this was loctited in place leaving a small clearance to the oil pump drive shaft. I then made a plate, sealed it with RTV and bolted it in place.
Following a test drive, this seems to have cured my 6000 Rpm ignition issue, I now seem to have another issue up around 6800 - 6900 Rpm. Not sure if I need to fit stronger valve springs or I'm having issues with the crank trigger signal.
My trigger wheel is mounted on the back of my crank damper, not sure if the damper is resonating and causing an issue, I think this is unlikely as I'm able to log all the engine signals and all appear to seem OK - I need to investigate further............
My valve springs were bought from Chris Witor, I'll give him a call in the morning a see what he thinks.
