Brent, I've just done the TPS calibration for my new carbs - it was a very easy process, but it left me with a puzzle. Where are the settings stored? I saved the settings to a file when the calibration was complete, but I had expected to have to save them to the MJ unit's memory too, as I thought th...

That picture was lifted from the web pages of Vehicle Wiring Products , but mine came from another source that's now gone ebay and they're almost impossible to find nowadays. VWP are a top-notch company that I can strongly recommend. They also have other types, from cheapies up to expensive ones. Th...

I have a ratchet crimp tool, similar to the one in the picture below. Effective, and really does give a good connection. http://www.vehicle-wiring-products.eu/VWP-onlinestore/terminalsnonins/images/pr4.gif It has 3 spaces for different-sized connectors. The Molex pins fit in the smallest one - make ...

One problem is when you insert the terminal into your crimping tool incorrectly. There are 3 tabs sticking out: 1 holds the sleeving, the second one holds the bare wire, and the 3rd guides the terminal in the casing. If you crimp all three then it won't stay in place - you have to leave the 3rd one ...

I saw similar problems on my car - I even posted a similar question on this forum. The answer (for me anyway) was quite simple. The EDIS coil is wired to fire 2 spark plugs at the same time. One spark gets a negative polarity impulse, the other gets a positive one. My timing light has a clip that go...

Regarding C14 - things to think about are:

Was it soldered in the correct way round?

Was it the correct voltage rating? (if it's from a kit, it was probably OK)

Did it get overheated when you soldered it into place?

Lee,

You might find this thread very interesting and useful...

In the end I used a knock sensor to drive an amplifier, then into a pair of ear-protector headphones.

The standard Ford coil has the cylinder numbers written next to the connectors. 1 and 4 fire together, then 2 and 3 I believe. On my Ford X-flow, cylinder 1 is at the front (fan end).

Just bear in mind that the trigger-wheels stuff has got heavy-duty sleeving that's reasonably oil- and fuel-resistant - I'm not sure that you could say the same about Maplin's stuff.

If you get stuck, http://trigger-wheels.com/store/ sells proper vehicle-quality shielded twin cable. I can testify that it's good cable!

Alexander,

Don't forget that double flash is normal! The system fires on both the compression AND the exhaust stroke.

The half-speed flash is the one to worry about...

David

Strange that your results with a timing light are similar to mine (1 lead twice as much flash as the other). In my case the strobe gave silly results, but the engine ran properly regardless!

In the end I decided to ignore the strobe... it was easier that way...

David

Alexander, I've had very similar symptoms to you regarding 2 plugs showing a good flash, while the other 2 don't. Does your timing light have a sensor that clips over the plug lead? The type that has an arrow indicating which way to put it on the lead? If so, could you try an experiment? On the lead...

was this measured with the car stationary? i think that would explain it all. if not, let us know so i can publicly disavow most of what i have said above :). regards alexander. Prepare to disavow! :P It was taken on a short run up and down the road. As for the 'ported' theory, someone else did a g...

I thought 1086cc was a bit of an odd size!
